Shakeyand Rough idle when warm

95-F-2FITTY · Apr 17, 2014

Well i have put new injectors in my truck, cleaned the ipr and tried unplugging my icp sensor to see if it helped my rough idle and it has not. My truck runs fine when it is cold or has set all night ,but once it reaches operating temp it starts to have a rougher shakey idle. Any ideas as to what i could check next? I am thinking it might be the orings in the ipr?

Bumping this up as mine is doing the same thing. I got a new ipr when I got my t500 so I know it's not that if that helps you. Does your Icp have oil in it?

No it sure did not but i got pissed and threw a new one on it and that straightened it out idles smooth again. So i guess what i learned is just because the sensor dont have oil in it doesnt mean it cant be bad lol

Good to know! Been trying to track down why it's doing that for awhile now. Thanks for the help
