I had these codes before here are my fix for these, code 16 it was a ICM faulty I ended up getting a new ICM also check if you are getting good ground to the computer and the ICM. For code 95 it was the fuel pump relay was bad that it could make good pressure when turning on the key but when u...

Sweet! Much appreciated :thumbsup:

I decided to double check on the timing marks but I notice another mark on the chain which I'm not sure where this chain mark needs to be the only marks on the Sprocket are the dots are lined up with the cam and crank. any idea where this chain mark need to be or its doesn't matter where this...

I'm sure I don't have any more vacuum leaks I checked for lines and don't hear any air getting into It could be the IAC and Yes TPS voltage is ok.

No EGR on a 91.

Fixed and more problems!! I'm back I have fixed my idle problem when cold start replaced 4 gasket and the PCV valve it start fine no problem now another problem comes in when its warmed up the idle goes up and down ill say to 900 to 700 fuel pressure is at 35psi, also got a code 41 System too...

Sorry for my delay Thanks guys for the help I have finally found my issue there was a vacuum leak in the intake manifold bad gasket and the pcv valve was not working properly. :D

Today I did more test to the ECT sensor I took the sensor out to test its Ohm resistance placed on hot water resistance slowly drops I think its reading ok, then I placed the sensor back on connected warmed up the engine ECT sensor resistance stay about the same as cold and volts were slowly...

It got worse and worse hopefully someone here had this familiar issue that could help me. I'm trying to fix this rough cold start issue, low engine RPM-500 it will do it again on the next day when engine is cold once engine warms up it goes back to normal RPM-1000. First thing first I tested...

Fixed! It's been a month now but I could found where the code was coming from I couldn't believe my new $200 ICM that I brought in August was acting weird I also found my coil pack and ECM has no ground this might have burned my ICM, now that i fixed my ground connections I connected my old ICM...

Don't forget your radiator fan cover and just so you won't break any brake lines disconnect your brake master cylinder just those two bolts on the brake booster. Good luck.

Ground cable and ecm were corrosion with salt and rust. now I no longer run the psi so low its back to 35psi. Grad that is fixed. :thumbsup:

Hey Harper! I will still had this issue if I put my stock fuel pressure regulator back on I decided to put a adjustable fuel pressure witch I have set on 18psi if I set it up higher it run pig rich now I think that injectors are firing too much I tried my stock ones still same, also I started...

First of all I was a little confused about the IDM code, I did some research now I can understand it more that I'm going to do some diagnosing first the best i can do before I buy a new PCM or a ICM. Any Suggestion where to start looking?

Wierd this code is telling me that my ICM is not working properly? I tested my MAF sensor with a multimeter its getting a good signal also checked connection and wires seems all good.

OK here the codes I got: KOEO:16, 66 KOER:11 I did the KOER test correctly 3 times which it gave me the same code 11 system OK. The way I clear codes I pull off the jumper wire while the key is on (test mode) which it I'm not using any scan tools I'm doing it by paperclip method test.

Yes this is a KOEO code and the code list I got it from here: http://www.explorerforum.com/forums/showthread.php?t=227663 another thing when engine is cold at idle is at about 1200 rpm then warm it drops at 700rpm which it run very rough. also I have replaced all the old sensor which all...

My truck is a explorer 1991 sport 4.0 ohv I have reset the computer and cleared the codes many times and I'm still getting this code 16 - RPM to low to perform o2 sensor/fuel test. I have replaced my o2 sensor 2 months ago with little miles on them, Anybody knows what I can do to fix it? Thanks.

I'm removing the stock fuel regulator and replacing it with a aftermarket adjustable fuel regulator which I need a rail adapter were the stock fuel regulator sits

does anyone know a fuel rail regulator adapter that can fit on my 4.0ohv? couldn't find anything that could fit on the rail. :salute:

Thanks Turdle for all your help! :)

It run great on the highway, here we have a lot of hills it barely goes up No brakes or emergency breaks dragging I found out that its running rich too much fuel this might be causing lack of power as I posted in post #14 , I will try out different injectors.

Thanks for your thought FR-425 Edit: Is the neutral safety switch can cause a lack of power? my truck is running is just don't have power I have to set it up to low gear to go up a little hill.

Alright I'm thinking changing the computer if doesn't do anything I might going to send it to the pro.
