hey guys new to this forum. I have been experiencing some issues with my truck sometimes it has power other times it chugs while accelerating till i hit bout 2000 rpms. Im at wits end i have replaced cps, ipr,icp,uvch's, hpop with 17*. No cells or codes any help greatly appreciated. this problem just comes and goes?????



the truck is a 1996 5speed with ts 6pos.

 

Where did you get the cps? Parts store ones are junk, get one from Ford, that's what it sounds like to me.

 

i have tried about 4 or 5 of them from ford even located an international black original same problem one minute it will run awesome the ext start missing. i also checked the cps wiring looks good

 

look into the injector wiring harness. i had a 96 that acted goofy, replaced a few of the pig tail harnesses and all was good.

 

Yeah, sounds like you have a UVCH problem if thats the case.

 

He said he replaced the uvch's.

 

so many acronyms there I missed it, Thanks for catching me O Bearded One.

 

yes i was thinking the same thing being it comes and goes like a had a short and the next minute not. I also forgot to mention its a got a new fuel/lift pump on it. Could an injector or idm come and go like this these seem to be the only things i didnt try. the truck runs darn good when it wants to lol

 

Injectors generally get fussy on hot or cold, not usually intermittent.

However the IDM will do whatever it wants when it wants.

If you have somebody who can swap IDM's with you or let you borrow one, try that out.

Yours might even have water in it and thats causing the issue.

 

yeah i have a freind who does but he has a sd and i heard they are a pita to take off. Ill have to see what i can brush up

 

Yeah, SD one will work, and yeah, they are harder to take out.

You can always pull yours and check for water or to see if it rattles.

 

im going to do that right now lol

 

looks good in there no signs of water. any other ideas i really dont know what else to try. Some times when it misses it is worse than others and its more of a chugging under load. truck always idles smooth.

 

Edit - disregard; thought this was a no-start issue....

 

I called in a big gun.

He should come help. I hope.
