Ford ECM Repair EEC IV | Fix Multiple Issues | 1980-1996 Ford Bronco F150 | Bronco Restoration

Thank you so much man i'v been struggling for 5 years to fix my truck it's been having transmission issues with shifting I found a shop last year that told me there is no signal going to ECM from Gauge Cluster all the trans shops around here have told me I need my transmission rebuilt when it has nothing to do with inside transmission it's been electrical I pulled out my ECM all 3 capacitors are leaking and I think it's like a fuse thing it's rusted bad

I have a 1994 bronco xlt and I’m having similar symptoms you were. This video might’ve saved my behind, I shall report back after I try this, thank you!

I'm having a no start on my 95 f250 5.8w abs light and check engine light are both on from one day to the next it stop turning on

Can you do a video on how you keep your engine bay so clean?

Hi … just wanted to say very well done. My truck (1995 F-150 XLT) started randomly stalling on the road. Mechanic did fuel pressure, changed fuel filter, added sea foam
Seemed to be running better but still rough at in the beginning and today driving a couple miles, it stalled again. Started reading forums and owners with the same problem mentioned the EEC. Your video really explains things and last, you have one clean looking engine.

Bro! I’ve been chasing some problems on my 91 f250 for ever. It hasn’t run in a few months but I just did new injectors and a new dizzy. Still not running right. I came across your video and said what the hell. Pulled my ecu and sure as shit, 2 of the caps were leaking and one leg was not making contact on 2 of the caps.I didn’t bother with doing it myself and just ordered a new one. To say the least I think your video saved my ass. Thank you for making the vid. New ecu comes in this wed and I’m pretty sure she will run great. If your ever in so oregon I owe you lunch😂

I got a 91 f150 4.9 4x4 with a high idle at 1.5 rpm while in park . Also dies whenever you put in any gear. Thoughts?

Great video. I assume this applies to 5.0 as well? I have a 1990. I have seen other videos showing loosening of the wheel well cover as opossed to the kick plate.

Your way looks easier. Thanks, Steve

My 1995 F250 7.5L has been stalling out at red lights or when slowing down. It runs perfectly when going down the highway and has no issues when cold, but once it warms up and I go to make a stop, it will 5 times out of 10 stall out and then fire right back up again. I just got a scan tool so I can work on testing it later today, but I'll add this to the list of things I should check.

Have you ever seen a bad ECU cause stalling like that? I'm also wondering about the IAC, MAP, and ICM, but I'm fairly new to these older trucks (I'm used to ODBII and having a scan tool to pull codes when something goes wrong).

can these go bad even if they don’t leak?

What temperature did you use on the soldering iron?

Thank you!

Awesome video, just subscribed! I have 1985 F-150 with the 5.0L. Truck starts and idles fine, but when I put in gear it stalls after driving about 10ft. Changed IAC, MAP sensor, coolant temp sensor, new battery, new ignition coil, and checked timing. Any thoughts on what my issue could be?

Hi where do you buy your parts at, am looking for a 986t04 driver for my fuel pump.

Now that’s a clean ass Bronco right there! Doesn’t look molested either! That’s a keeper!

Thank you so much for the info...!!!!this video was superr useful!!!greetings from chihuhua mexico

I bet Murphys Law messes with you in the way that every time you solder, no matter which way you sit or face that the smoke goes straight to your face. Oh and I love the wire tip for getting the old solder off.

Just took mine out but it’s still clean :/

Nice video, I got a super clean 1993 Glaval Universal E150 conversion van that’s having some awkward issues that apparently has cost a family friend hundreds of dollars to no avail and was given to me to solve it and since it’s mine if I do my motivation is high. They replaced the sensors form transmission to the cluster and nothing ever fixed the bouncing speedometer and rough shifts and I’m certain now I have a capacitor issue after this video. Great work and damn nice bronco

Good video as always. I have problems with the parking brake, do you have any video of that?

Is it normal that my 1987 bronco only have 1 capacitor? And the label in the EMC says 3.0 Taurus Sable only

Excellent DIY Video..I think you did a great job making this video.
However; Don't know what year your Bronco was, but it didn't work for my 1994 Bronco XLT 5.8.
After removing the drivers side kick panel I could clearly see it didn't match your video and there was no-way the EEC-IV was coming out from the inside.
Mine had too removed from the engine compartment of the drivers side fire wall.
So for anyone doing this, double check to see if your EEC-IV is removed from the inside side of the fire wall or engine compartment side of the fire wall.

Nice looking Vehicle.. Don't know what year your Bronco is, but looking at the vehicle photo I'd guess it was a 1993 or earlier.

That truck looks better than when it came off the showroom floor. I just did about everything to my 1991 except the computer capacitor replacement but I am definitely doing it now. Thanks again. Isn't your front gearing a 3.54 like mine. When I serviced mine I noticed my front was 3.54 and the rear was 3.55 on tags. Beautiful truck

You bet, i have a question i wonder my ecm has only one capaciter 1989 bronco ii i have the same symptoms with shifting first gear terrible acceleration and chopping mufler sounds, it idles a bit low and if you do a quick and sudden step on gas it kinda wants to stall at first then stutter and rev up! Any thoughts? Thank you also shakes after 3rd gear untill i adjust my step more or less on gas. Nothing is wrong with the exhaust system btw. Thank you

My god that truck is Beautiful

There is this kind of satisfaction to watching someone that knows what they are doing. Also working on clean components is fun to watch. Thank you for the video

You're the man! Thanks for sharing.

well done ! To the point, easy to see, and well demonstrates process; with great tips on removing solder

You should try to take better care of your bronco man. Lol absolutely beautiful truck!
Great info also. Very cool. I have a 1990 that is a dedicated off road rig with the same issues. I will be excited to give this a shot

I checked my ecm, capacitor wasn't leaking...
Maybe pick up coil?

Man you got an absolutely mint Bronco.
Thanks for the vid.

Outstanding video

Great video. Where is the best place to buy the capacitors?

Thank you 🙏

Dude this was super helpful! I have a 96 bronco now and used to have a 90 that I loved as well!

Yet another excellent how-to from The Fix. Thank you sir!

Ppl tell me my 94 bronco is clean but this one is like brand new. Thats a clean bronco. Im actually having the idle issues and i have replaced the usually parts like the one you name and more. Great break down video

great video and how-to. I have an 1989 Ford Bronco 58l with C6 4x4, do these 3 capacitors affect the fuel pump function? My Bronco won't turn my fuel pumps on- only if I remove the fuel pump relay and jumper wire the hot to the pump will it run them and then I can drive it.

Zow! Rub some of that smart off on me. Thanks super tech.

vehicles were relatively simple in those days I bet you cant do that on a vehicle made from about 2000 onward because they intentionally overcomplicate things.

man that thing is so clean you can eat off it , Brand new like. most of these are worn out and in rough shape , especially the pickup trucks considering most people use them as workhorses.

Bro, I am literally crying. I have been trying to diagnose my 1992 f150 5.8 for almost two years. Have replaced basically every sensor, wires, hoses, etc. I've read hundreds of forums trying to fix this rough idle, intermittent dying, zero power, absolute BS running rig. You're my f**king hero, man. Thank you, thank you, thank you!

Can a capacitor be bad without leaking. I had a constant running fuel pump and a no start condition. I replaced 2 capacitors that were leaking but left the 3rd capacitor alone because it looked fine. The fuel pump stopped running constantly but the engine still doesn't want to start. Needless to say I didn't see your video first.

so glad I found you’re channel, just picked up a 90 bronco xlt🤝🤝

How do you know if you're getting new quality capacitors ?
Where do you recommend getting those Panasonics from ?

Is there something else I could plug into that connector? Like and aftermarket engine management system that won't break.down like this?

God bless you! That is one nice Bronco! Thanks for the knowledge, going to do mine while I'm down for maintenance. Your an excellent instructor, simple and well explained, especially the detailed capacitor notes! Now I can order before tearing into everything.

Use Solder Wick to suck up / extract the old solder ; Use a good quality Weller ( WE1010NA ) soldering iron ; that means no HARBOR FREIGHT JUNK ; Also its preferred that you use an anti static mat designed for electronics repair that is grounded ; other wise you could zap the electronics with a static discharge.

Thanks very much!
