[@mikelarsen7594]

You did a good job on your video, You mentioned replacing the spring clamp for a hose with a screw clamp. The reason spring type clamps are used is so they can expand and contract a temperature changes. Over the log term the fixed tension screw clamp will get loose and may leak. tightening the screw and the thermal expansion and contraction will eventually make the rubber hard and may crack. So using those spring clamps that seem cheap is better for hose life. Screw clamps are also available with built in springs.

[@motorsportfactory]

hey thanks for the comment Mike. yes i agree with the spring clamps and what they are meant for. i choose to use screw clamps for myself because it just becomes easier to access in the future

[@mean1flyer]

Motorsport Factory thank you, my Altima is a 96, kinda old but i like it cause we have never had a problem with it until now, it really deserves to be fixed, the egr is good now it was a bad vacuum hose

+Motorsport Factory So I installed new idle air control valve and the new one is whistling loudly??? why is this? aside from that, my car is still idling wrong though before I installed the new one I took off the old one and cleaned it and it worked great for one day. so why am I not getting the same results from the new IAC ?????? please help!

[@motorsportfactory]

you could be having other issues. that may not be really coming from the iac. things to check is do you have a cel?.... its really hard to say whats going on with your car without diagnosing it. because if you are getting same results from either iac... also make sure that the iac is adjusted correctly too. ill help as we go along with this

[@motorsportfactory]

the other thing is did you use a new gasket? if not then thats probably why its whistling more . also check other things such as tps sensor,oil in the distributor.

Your IAC has the "square" mounting flange. There is also a version with a smaller rhomboid shaped flange requiring more disassembly in order to have clearance to the upper bolt closest to the head.

What was wrong with it? Why did you replace the IAC? My Nissan stalls when I turn on the AC.

[@motorsportfactory]

@@urielmunoz1011 well i did notice it was clooged with carbon. main reason why i changed it was cuase car started hesitating on acceleration. but come to find out i had to change other things too like the distributor and stuff. if you having these issues check plugs,wires, cap, rotor,distributor,check CEL codes ,check for vacuum leaks

[@ralphreyes2440]

Great video If I turn on my air conditioning and or just the fan the engine dies is this the cause also? please advice thanks!!

[@motorsportfactory]

it could be. but it always better to diagnose the car . just cause the symptom is the same dont mean it caused by the same issue. check for CEL codes. check vacuum leaks. and go from there

[@82thunderlegacy85]

having the same issue noticed u mentioned a coolantbsensor is on the valve,would that explain why my coolant gauge fluctuates back in fort with the rpms? and if so is the part bad or just the sensor?

[@motorsportfactory]

well you have to test everything to see what is really causing it. its really case by case . it could be the sensor itself. but i believe i said the coolant sensor is by the valve not on the valve itself. the main things to look for is vacuum leaks,check ignition system, fuel system, mas sensor, check to see if you have stored codes. its best to diagnose the car before replacing anything

[@danielmejia6166]

Hi, I got a 98' Altima and it has a lot of problems like you mentioned, vibration, the AC didn't work properly and sometimes the car wants to shut down, do you know if the same steps needs to be done to replace the IAC on the 98' model? sorry for my English

[@motorsportfactory]

every car that has the same issues may not be all coming from the same area. always check everything on your car to verify what it could be. check for all ignition parts to make sure they are in working order, check the fuel system ,check for stored codes , if you have a check engine light then check what those codes are then go from there

[@prime_era_kills3901]

Hi there, my Nissan Altima 97 sat for a month with a full tank on gas while I changed the faulty water pump. (Gov work outta town couldn’t do it immediately) before I replaced it the car wouldn’t start. I replaced the wp and replaced the valve cover gaskets because there was oil in the spark plugs 1 & 4 and there was some gunk on the

On the coils. It wants to start cause it cranks and turns over a little bit but don’t know what to do now. The analyzer I have shows the code P0505 could you reply back thank you

[@motorsportfactory]

@@prime_era_kills3901 that code sounds like a idle air valve. it could just be plugged up and needs to be cleaned out. or replaced. but also check other components that can be an issue like distributor to injectors just to be on the safe side

[@darkdream8253]

did you have to take out the oil filter i have a 96 altima and i need to do this i hve the part and ll the tools just not sure if i have to take out my oil filter so i can get more work space also figured id change the pcv valve while im in there

[@motorsportfactory]

it can be done without taking out the filter. as i did in this video. but you can take the filter out . to get more access to the big hose thats attached to the iacv .and yes i have a video also on taking out the pcv. just follow the step to taking this out and you can see the pcv .

[@chrisjarvis955]

1st you should have started it and let it run with the problem. then after the Fix you should have done the same to show that it is running better. But thanks for the video this might be my problem going to try and do the reset 1st.

[@motorsportfactory]

i know i really wanted to do that. to show the problem areas that cause this. but i had so much going on i just focused on the repair it self. but next time i work on one of these im gonna make a version 2.0 of this with better camera gear etc. and will go through the diagnostic and testing process and then replacing it

[@OscarBadillaApuy]

Very helpful video, my 95 Altima reports the 505 error code too. I had a very bad time figuring how to remove IAC system to clean it up (before viewing your video), when I did it, I took off the oil filter to make more work space, I am wondering if It was not necessary. I understand idle state problems you mentioned, but my car also experiences a lack of power mainly when driving up hill. Might it be related it to IAC fault too?. I have changed sparks and its cables, there are no other error codes. Thanks for your help.

[@motorsportfactory]

+Oscar Badilla taking the oil filter is fine. no need to worry if you take it off or not. taking the oil filter and the filter housing is good to take out when you want to change pcv valve . thats when you will really need space. if your lackin power is probably anything from needing tranny fluid flush or clean mass air flow. change the fuel filter if you have not done it. if you do decide to change pcv valve make sure to change the o ring in the filter housing or use rtv .or you might need new timing chain.

[@OscarBadillaApuy]

+Motorsport Factory . Thanks for your advise, you mentioned many important points, so I would like to talk about each one: 1-Automatic Transmission. I have already changed trans fluid recently, I removed pan and found two dirty magnets in it. So I cleaned it all, I didnt find any oil filter, should it be?. Oil didnt smell burned. Problem I have is that when I shift from reverse to drive or viceversa trans takes little time to react (get traction) and if you press accelerator pedal when change, you will hear a hit in it. 2-Fuel Filter. I will change fuel filter. 3-Mass Air Flow. Please advise how to clean MAF sensor. The original one had to be replaced time ago with a used part. I experienced intermittent lack of pwr that time, perhaps it is faulty again.And I think this is the main suspect. 4- PCV valve. It is hard to reach according to I have read and it is reachable only from below, so I would like if you can tell me some hints to verify if it is malfunctioning before trying to replace it. Now you know I love this car, It is an Altima 95 SXE. thks again.

[@motorsportfactory]

the auto tranny filter is mounted right above when you take the tranny pan off . you can see it. here is link to show what it looks like www.partsgeek.com/gbproducts/DC/6668-05384114.html?DN&+Nissan+Altima+Automatic+Transmission+Filter+Kit+Pronto+PTK1234+93-01+Nissan+Automatic+Transmission+Filter+Kit+1995+1997&fp=pp&gbm=a&PartsGeek+Google+Base&gclid=CjwKEAjwgbG5BRDp3oW3qdPiuCwSJAAQmoSDeGD_h4lEuL2L2Tqt9Dd_Xbz9iDhUCGg8IJhtA8FAzRoCFLHw_wcB&ad=47584901292 to clean mas air flow you must use only mas air flow sensor cleaner. do to specific materials the mas air sensor is made of. the cleaner is specialy made for cleaning that. link to cleaner www.zoro.com/crc-electronic-cleaner-16-oz-aerosol-05110/i/G2052416/?gdffi=047ada998cf641fa93e55ae8579df863&gdfms=FD1B86B6A6D14888A68D5EBA7AB06C81&gclid=CjwKEAjwgbG5BRDp3oW3qdPiuCwSJAAQmoSD38mQTdRbwPfHCbHQw5nNNOvsX6SNkH9jKK7FDf23PhoCtUPw_wcB&gclsrc=aw.ds to get to pcv just follow my video after taking out the idle air valve. then just follow the video. i didnt repeat the steps in the removal of the idle valve cuase it would be to much time. so follow this video and once you get to taking it off then follow this video on removing it kzbin.info/www/bejne/qKC0h6Nph9-Mndk do replace the pcv while your doing idle air valve its much easier and not have to work twice . so while iacv is off just work on the pcv too. also your car may need tune up if never done. have the timing chain also inspected . that may need replacing too. hope all this helps

I finally got the IACV on and seems to be working ok CEL is off but idle is a little high, should be between 650 and 750 rpm. but it's like 900 rpm. Any advice on how to adjust the idle down. I'm thinking the IACV is preset but I don't know. Can you advise me on what to do? Thank You for your help.

[@motorsportfactory]

+Hubert Goins hey Hubert if you seen right toward the beginning of the video right where i went in to show where the iacv is you can see the black screw right?..... thats your adjustment. i was thinkin the same thing when i first got mine. have another person with you to help monitor the idle, to see if its goin up or down when adjusting. and turn it slow so you dont stall or have it revving to high. i believe you turn it counterclock wise to bring it down some. let me know if this helps

[@hubertgoins7488]

+Motorsport Factory It's been a month,idle still seems high and can't lower it, CEL is still off but still reading bad knock sensor. I was wandering if it is possible to relocate the knock sensor to a different spot on the engine and where does the knock sensor wireing connector plug in and can you get to it from top side (under hood).If so please let me know. And again thanks for your response on the IACV issue.

[@motorsportfactory]

+Hubert Goins stilling having high idle. hhmmmm you may have some thing else going on like check for vacuum leaks. change that knock sensor when you can . i will make a video one once i have a change on how to replace knock sensor .yes im sure it is possible to relocated the knock sensor but i havent done it yet. there are people saying that you have to remove the intake manifold to get to knock sensor but i think it can be done from under the car like we see in video. also check to see if you have oil in the distributor by taking the cap dist cap off. you did also change the iacv gasket when you were replacing it right ?

[@hubertgoins7488]

+Motorsport Factory I did replace the IACV gasket didn't see any leaks. The knock call for five hours labor, it looks likr a worst job than the IACV, sure hoping it can be moved. Appreciate your help.

[@motorsportfactory]

yeah the 5 hours is with that if you were to take the intake manifold off . but i will work on a video sometime this week or next week to help you guys out.

[@johnmills1414]

I am sorry but hit post button by mistake. To continue. Is this a similar symptom you were having with your car?

[@motorsportfactory]

yeah that was one issue. check the distributor for oil build up. take cap off and see. also check fuel pump and injectors. also fuel filter. sometimes the basics is all it needs

[@hubertgoins7488]

I am trying to install my iacv by myself and I'm having a hard time, did you take the bottom hose completely off and reinstall it after you bolted the valve back on. Which bolts did you put on first? Please help I'm having the hardest time lining everything back up, I'm not the best mechanic but I couldn't afford to have it done in a shop. Please help, I need my car. Thank you!

[@motorsportfactory]

+Hubert Goins as far as the bolts i started with putting the bottom bolts on. and at the same time getting the 2 hoses on as well.the longer hose has plenty of slack. the short one does not. the longer hose can be taken off while still bolted.the short one and the bigger diameter hose can only come off as you take off the iacv. ive also learned a little hard way to take off the bottom larger diameter hose. if you take the oil filter off along with the filter adapter block you will have more clearance to the large diameter hose clamp. but do know that if you take the oil filter block off you will need to replace the oring seal that sits inside it. i will be offering that seal soon.. while you at it you can access the pcv valve also . here is the link to that video too if you wanna do the pcv. kzbin.info/www/bejne/qKC0h6Nph9-Mndk i hope this explanation helps. if it does please let me know. and dont forget to subscribe and join me on facebook

[@motorsportfactory]

+Hubert Goins no problem. i understand your situation. also remember to replace the gasket too to prevent leaks. and it was also a bit hard for me to , to record and working laying on my back. i wish i had a lift but i dont at the moment . never worry about rushing. always best to take you time and do it right the first time

[@mean1flyer]

hi, i know this is a year old but I'm just wondering, what does the iac do? what are the simptoms of a bad iac? thanks in advance

[@motorsportfactory]

+Rafael Moreno The main function of the IAC valve is to ensure that your vehicle idles smoothly. However with a bad IAC valve, this idling will be rough. You will experience heavy vibration (shuddering) when you idle the car. As the valve has gone bad, there will be no/very little air flow to the engine, when you idle the car. Thus, your car will shake, vibrate, and may also make a loud noise while idling. Due to this rough idling, the next time you start the engine (the car), you will notice that the car stalls immediately after starting. Your car's IAC valve might be clogged with carbon debris, and due to this, the valve might not open sufficiently enough to let the air to pass through it. Under normal conditions, when your car is idling, if you turn on the AC or heater, your vehicle will still idle smoothly. However, if the IAC valve is faulty, your engine will stall the moment you increase the load (AC or heater) on an idling engine. You will also experience a drag on the steering wheel once the AC is switched on. To restart the engine in such situations, you should turn off the load and wait for few minutes for the engine to cool down before you crank it up again.
