Thank you papaw, my wife's truck that she loves was saved because of this video. We have been chasing this problem for a long time and the ICM was our problem!

I installed a 1990 4.9 into my 79 f150, converted the intake to a carb and set a 54 one barrel carb on it and set a point distributor in it, runs like a haint. Installed a 5 speed hydraulic slave trans in it from the 90 f150. cut and redid the pedal to push the slave. pro job.

It’s on the distributor on my 1990 f250 351w. They are prone to having problems

What is the correct part number for an ignition control module for a 1995 4.9l f150? Because they always sell the wrong part number and the people at the store don’t really know either

Lol thanks for having us told timer. God bless

Hi Kenneth, I saw your comment on Dr. Bergs video from 6 years ago and was wondering if you and your wife were able to kick the smoking habit for good. No shame if not. I hope you’re both doing well. God Bless.

There could be several possible causes for a 1990's Ford pickup truck to idle with erratic RPMs. ⬇️ Here are a few possibilities: 1. Vacuum leaks: A vacuum leak can occur when there is an air leak in the engine's intake manifold or hoses. This can cause the engine to idle irregularly. 2. Faulty idle control valve: The idle control valve controls the engine's idle speed. A faulty or dirty idle control valve can cause the engine to idle erratically. 3. Dirty or clogged air filter: A dirty or clogged air filter can restrict airflow to the engine, causing it to idle irregularly. 4. Malfunctioning throttle position sensor: The throttle position sensor monitors the position of the throttle and sends signals to the engine control module. A malfunctioning sensor can cause the engine to idle irregularly. 5. Faulty fuel injectors: Fuel injectors spray fuel into the engine's combustion chamber. If a fuel injector is faulty or clogged, it can cause the engine to idle irregularly. 6. Malfunctioning EGR valve: The EGR valve recirculates exhaust gases back into the engine to reduce emissions. A malfunctioning EGR valve can cause the engine to idle irregularly. ♦️ One time I took the EGR valve off of an engine, I replaced it with a new EGR valve to no avail. So after that I took off the EGR valve and I put a flat metal plate over the hole and reinstalled the EGR valve. After that it was completely fixed. To this day I still cannot figure what happened there! 7. Then there are the PCM and the ECM. Us older people refer to those as the computer or the brain. The fundamental distinction between the two is that the ECM regulates and sends orders to particular areas of the engine. In recent models, the PCM controls practically all engine functions. However, there is a narrow line that separates the two. Most people, even automotive professionals, mistake the two. The ECM and PCM govern engine operations that must work together to burn fuel effectively. When the engine stumbles, coughs, or stalls, it may be due to the PCM or ECM failing to regulate the fuel mixture or the firing of ignition components 8. Then last but not least is the electrical system. It could be faulty wiring anywhere on the engine that runs to any controlling component of the engine. ♦️🩺🔧🪛⛑️ My mechanics instructor when I went to vocational School once said: "Being a mechanic is just like being a doctor. You must be able to diagnose the problem before it can be fixed ❗" 🔨⚒️🛠️ If I have ever heard a true impacting statement that was it ❗ It's important to have a qualified mechanic diagnose the issue to determine the exact cause and recommend the appropriate repair. 🥺 After all, they've got the fancy computers and electrical equipment that we just don't have........

Hi Kenneth, thank you.

Peaceful and very much like home to me. Thanks for sharing

I meant to do this in landscape view. The video still turned out okay, but not as broad of a picture as I wanted.

🤔 Here's another thought: Many people, including professionals, get confused by all the acronyms used in automobile mechanics. A PCM or powertrain control module is different from an ECM or engine or electronic control module, even though most people believe the two are the same. Most modern or newer models only have a PCM, which controls all the engine functions, where the ECM only controlled certain parts of the engine. ECM Some of older automobile models had two computers, the ECM and the TCM. The ECM controlled the engine function, but the transmission was controlled by a different computer system called the transmission control module, or TCM. The ECM was also used with vehicles that operated with a manual transmission because there was no need for a computer to operate the transmission functions. PCM The PCM is the main computer in the automobile that controls all the functions of the vehicle. Everything from the vehicle's timing to the proper flow of fuel into the fuel injection system is under the control of the PCM. Along with the engine functions, the PCM controls the functions of the automatic transmission, such as automatic shifting when vehicle is accelerated or downshifting when the vehicle slows down. The PCM does not have as much control of a manual transmission. 🔧 🩺 I hope this clarifies the situation a little about the old term "COMPUTERS" LOL.... 😀 🤖 💻

This device is my last component to replace. On mine it's on the distributor. It runs so crappy apon start up. Once it's good and hot it runs close to perfect

Hah that's the guy from the old guy awkward smile memes

Lots of belt and belt component noise! CHEERS from here!

Amen

It did help. Thank you kind sir!

What do i do if that screw is not there anymore where would i get one that small from and is that the cause of my civic shutting off after it starts to much air getting in ????

yea. replaced that on my 96. .. still does it. about to drop in a new hei distributor.. fingers crossed

Just put one on my 95 with a 5.0 that was doing the same thing, found that one of the screws had came out so it was not grounding ptoperly

Thx Ken

286k on mine

No tach onine

Outstanding, same as mine and I love it

I'm having a very similar issue with my 78 mustang tachometer is all over the place misfires when cold seems to get better once it's warmed up but something definitely isn't right and I can't figure out what it is!

🙏 Amen.

Nice truck

Thanks a ton! Great color on that truck

GREAT HELP

Genius! Fixed mine

Hi, I have a 4.9L straight 6 and my truck vibrates and makes a creeky sound occasionally but not all time also sounds like air flow is louder, like shoooooo air, if you know what I mean, Vern. What do you think it could be? Any suggestion is appreciated and your truck sounds like a solid horse.

Hi there do you replace the pcm

this guy fixed my car 🤔

On my 92 f250 351 it was the ground wire got the hole truck for 1k the previous owner had rebuilt the engine and still couldn't figure it out

Thanks big help 👍🏻

Just a footnote on repair manuals. Most part stores are no longer selling repair manuals because everything is going electronic on smartphones. This is very sad because repair manuals we're very very helpful when it comes to working on your vehicle, they showed so much detail on so many aspects of your vehicle. The electronic age is going to hurt the small people like me, I cannot afford a fancy computer for diagnosing automobiles. I am what you call a shade tree mechanic old school, I don't do enough repair on vehicles to justify a computer for diagnosis. I usually buy the manual for the Make and model of vehicle I am driving. The newer vehicles are made so people like me cannot work on them at home, therefore you have no choice but to take it to a modern-day mechanic who has all the expensive computerized equipment, that is why they have to charge so much to work on your vehicle because they have to pay for their equipment and you cannot blame them for that. The shade tree mechanic days are over forever, in the next 10 years it will be a thing of the past.

Thanks for the info, I've tried everything but that. Hope it works.

I dont have a tach. I think the previous owner put in a junkyard dash/display. Is it suppose to have a tach? I also deleted the smog system. Maybe that's the issue. I've been told egr delete wont make it run bad, it just puts exhaust into the intake. I'm still hunting down issues with mine.

Had a similar problem on my 95 4.9..turned out to be a bad pickup sensor in the distributor

Dude this helped me out 100%

Thank you for the video , I also own a 95 4.9 . All videos help.

What color is your ICM? I know they make two type,, one black and the other is gray? Good informative video.

Best engine made, still driving my 93 manual. Having issues w my dash cluster, sometimes I know how fast I'm going sometimes 🤷😂

Kind sir would you be willing to film or sending me a message showing how your vacuum lines and EGR lines are connected? My truck has been worked on and I'm not sure the lines are connected correctly and I can't seem to find that information anywhere. I would very much appreciate it!!!

Can't beat the old 4.9. I'm subscribed

Seen this video before if you have a hard start rough idle and chuggy acceleration or break up like your running out of fuel it could be the vacuum can (aka coffee can) other fender well i changed everything wire harness computers injectors fuel system even a full engine rebuild and truck ran same as when it all started 2 yes ago and found I had a huge n very quiet vacuum leak I putt a plastic round vacume ball on and this 300 is has some serious power now its all fresh n correct so jst saying for anyone having trouble and can't figure it out after replacing expensive sensors check that can mine had Swiss cheese out rite under the mounting part couldn't see it now im 8000 in under hood after missing this but its pretty everything got painted while apart

I have a leaking injector. It goes away once the engine is warmed up. But anyway it does the same thing

Sorry I haven't responded to some of your questions. For some reason I'm not getting any notification about responses to my videos and I'm seeing so many from months ago I figured it was too late to get back with you guys. Again sorry about that.

Got something funny to tell you put all new parts ICM and top of the line coil pack Accel on my 4.9 would not crank put the old Parts back on it and it cranked and ran now after it warms up it starts running rough go figure anybody can help thanks

This helped thank you

the older ones are on the distributor, keep a spare in the glove box!
