NOTE:.... If your Car / Truck Stalling after Cleaning and replacing all that stuff, etc...... You might want to " RUN " the Engine at " Idle " for a bit, so the " MAF Sensor " can Calculate your Fuel Ratio. Your Engine might be just fine... Just the MAF Sensor has to talk to the Computer. so it can " Re-calibrate " your Fuel.

[@justinsmet]

My question can any of this deal with high idle

[@JodBronson]

@@justinsmet - YES, after cleaning it can..... Sometimes it can be High or Low, low enough that the Engine keep dying. As stated above " after Cleaning and replacing all that stuff, etc...... You might want to " RUN " the Engine at " Idle " for a bit, so the " MAF Sensor " can Calculate your Fuel Ratio. ".

@@JodBronson the iac is bad or vaccum leak

[@worshipwhilewewait]

OK so I started watching this because I was having problems with idle things so I find Your vdo and start thinking, "who is this depressed Woody Allen sounding Guy?" Little did I know that YOU are brilliant!!!! FIRST TIME? Dude - you KILLED it! I don't know about the soap and water for cleaning (would rather use throttle body cleaner) but if you dried it like you said, it's gotta work! I'm like you - hey, I'll give it a try. Learn more about Myself than anything. You keep doing things like this and your Gift will seat you before KINGS! THANK YOU for showing me a "how to" that I've been searching for a long time. PEACE!!!

Praise God, and what a blessing, finally got my truck running after months.

[@JodBronson]

Nice and I am glad it helped you! Also, if you have "Idle or Starting" problems. The Idle Air Control Valve (IACV) may need replacing. I got one for $8.00 on ebay and with free shipping. It can eliminate a lot of headaches. NOTE: I became very knowledgeable with the Engine - 4.3L, so if you have questions, just ask. I can save you a lot of $$$ on repairs!

[@prohomevideos]

@@JodBronson I haven't replaced or cleaned anything yet but wanted your opinion on something. My 4.3l has been idling a little low lately and I was told not to adjust the idle screw to increase it but there is an idle screw and I am tempted to give it a couple of turns. What do you think?

[@JodBronson]

@@prohomevideos - Before you do anything. TRY THIS: Go to an auto store and buy MAF Sensor Cleaner. Then clean your MAF Senfor with it and WAIT until it dries completely. Now turn your engine back on and wait and idle for about 15 minutes. The computer will adjust the fuel ratio and it should be back to normal. IF NOT, then it's something else !!!

[@prohomevideos]

@@JodBronson Thanks for the tip. I did exactly what you said and the throttle still was low. Btw, the MAF sensor was pretty clean but I cleaned it anyways. I decided to remove and clean the throttle body and look for any vacuum leaks but didn't find any problem. The throttle was was at 850 and then dropped to 500 after a couple of minutes. After 15 minutes, I started to rev the engine and then the rpms dropped so low it stalled. Do you think the IAC could be malfunctioning?

[@JodBronson]

@@prohomevideos - The IAVC is easy to take out, so why not? Take it out and clean it too and then put it back. Also, when you take it out, see if there are lots of Oil on it?

[@williamcox2996]

awesome video...will do this to my s10 v6 4.3 68k miles idles crappy i am sure this job has never been done by prior owner...I like simple green for grease instead of soap/water...works faster

Thankx! You know they can't stop me! LOL

[@ghouliesgarage3922]

THANKS! Super Informative ! GODSPEED !

[@JodBronson]

You are welcome!

[@JakesTrucking]

The IAC allows the engine to idle up when the engine is under load and prevent it from stalling. For example when you turn on the A/C.

[@JodBronson]

Ah ok, that make sense, thankx!

[@cliftonmancias1910]

Jake Gmail so if the truck turns off while turning on ac or putting it in drive or acceleration hesitation or vehicle start hesitation the iac is bad

[@JodBronson]

@@cliftonmancias1910 - If you turn ON AC and your Truck shuts down, WHILE the Engine is NOT running... There are a few things. #1 - If the AC Coil Compressor is bad. It's sucking too much Power from your Battery. #2 - You don't have enough juice to power your AC. Turn on the Truck and then put AC ON... See if the Truck shuts down, IF NOT, then you just have LOW Battery. #3. If your Truck is ON and your AC is on, and it's Shutting down... Then either NOT enough Battery to power it or Alternator is not giving you enough Power to Power your AC.

[@stockman1963]

Actually I rotated the Throttle cable spring keeper and the cable does not take up slack on it own. Is that right ? the spring loaded item cable goes in to -- push around towards to front of the car. Does the other end automatically take up the slack on the other end.

[@stockman1963]

Thank Jordan Bronson, It was MAP, even though I cleaned it 3 times with carburetor cleaner it did not work, finally bought some electronic parts cleaner and cleaned and code has been gone since.

[@JodBronson]

@@stockman1963 - Cool, you''re welcome!

[@roadstar499]

Okay i have done everything to my 4.3 blazer except this... What was this doing that made you think this would fix...my truck bucks and hesitates lacks power...thanks

[@JodBronson]

+roadstar499 - It was starting a bit rough, that is when I decided to clean it. When it's " Lack Of Power ", it could be a few things and depends. 1. Your Ignition Control Module. 2. It could be your Spark Plug. 3. Check your Distributor Cap 4. Check the Ignition Wire that goes from your Ignition Control Module to your Distributor Cap. *NOTE:* Do you have " Lack of Power " during under 50MPH ??? If you *only* have Lack of Power only when it's 60-70+MPH.... Then it could #4 above.

[@roadstar499]

thanks...mine does not have the issue you had... i just ordered a tps... it seems to be better today after replacing Maf connector and adding an extra ground wire... i did replace cap but it was a cheap one..it could be causing issues.. also replaced timing chain... Thax again!

[@justinmartin7875]

@@roadstar499 did you ever figure out your issue? Definitively?

[@roadstar499]

@@justinmartin7875 yes and no... i fixed it by doing several things making it considerably better...but it still is not right..i have been real busy and truck has been sitting for months...spent way more money than i should have...its best to take time finding out exact issue before buying parts and putting in hours of work... I will probably work on it again in near future for another few hours than just sell it as is... sometimes u have to take a loss and move on to keep your sanity...

[@JodBronson]

@@roadstar499 - If you Truck / Car "Hesitate" during acceleration or anytime it goes over 65MPH+..... It's more likely WEAK Ignition Coil Wire.... Check the Wire that goes from your Ignition Control Module to your Distributor Cap.

[@miguelfiske7626]

Mine is not spitting or spuddering it's just idling at 1000 rpm constantly what is causing it?

[@JodBronson]

Check your TPS or IACV

[@stockman1963]

Hi Good video, My throttle cable seem to have slack in it. I see yours looks snug tight - straight. should all the slack be out and do you think that would make a P0101 code ? I fixed all the vacuum leaks and every thing else.

[@JodBronson]

Code P0101 is set when the signal from the mass air flow sensor is out of expected range, or in other words, the MAF sensor doesn't work properly. In most cases, this code is not very difficult to diagnose. Check all the Cable close to your MAF Sensor to make sure that everything is seated correctly. Also, they have a MAF Sensor Cleaner, you can buy it and try to clean it.

[@JodBronson]

As for the Cable, there should NOT be any slack in it, just a tad and like 2-5mm most. Your Cable might be out of place, like not put in correctly or the Cable has been stretched through time. After checking and everything AOK.... You can use the "Zip Tie" method and go INSIDE your Car and follow the Acceleration Cable / Gas Pedal... Pull the cable until tight, add a few Zip Tie to make the cable tighter!

@@stockman1963 - After cleaning your MAF Sensor, you have to idle a bit, so the Engine knows how to "calibrate" your fuel ratio again.

I cleaned the throttle body and iac valve and it started went for a spin and at low speed to see what happened everthing worked fine and came back home shut the truck off 99 s10 and now it wont stay on starts and it shuts right off even if i step on gas while starting. Do you have any advise?

+Monte Tommy - Google and send me a link? I won't be able to understand what you are talking about ://

[@alexsbikesandmotors]

he's talking about that early GM throttle body injection that looks like a carb but has 2 injectors at the top of the throttle body that squirt fuel down the intake

[@JodBronson]

+Alex's Bikes and Motors - Ahhhh... Ok, I know what you are talking about now. My Dad's older S10 have those injectors. THANK YOU !!!

Jordan Bronson I found a tbi at a pick in pull I really don't know how to take it all of or what I need the car runs ok just feels like it's gonna quite when I put it in reverse it rids sluggish so I know it's the throttle body I just don't know if I need to get the whole throttle body or what

+Monte Tommy - Did you try to " Clean it ", most of the time you can clean practically anything, except for " Electronic " parts. Did you try Carb spray? Also, clean the Throttle Position Sensor?
