Have no codes on scanner. 93000miles. Changed plugs and wires, air filter. No change. Cleaned throttle body , nothing. Ran lucas, then at a later date heet. No change.
Is there a common seal or oring that wears out? Is it a vaccuum leak idk? Took it to a mechanic said no codes nothing wrong.
Is it the fuel filter, motor mounts.
Getting tired of throwing money at it plzz help.
Just clean sensors no change. Seems like it running lean.
Also seems fuel related being it does it warm and cold?
Im going crazy ahhhhh, lol thx for the help.

 

what spark plugs did you use? and do you have access to a scanner?

 

Bosch, yeah at oreilys or advance. Going to run fuel pressure tests tomorrow. Just hoping there was a common problem, like fuel pressure regulator. Its a drive by wire throttle so it makes it a little tricker to figure out. But thx for the advice ��

 

I wouldn't put anything other than acdelco plugs in a gm, I've seen a lot of instances with symptoms like yours where just putting in the OE/delco plugs fixed it. Otherwise you need a scanner that can show misfire data and fuel trims to get an idea of whats happening.

 

Cool ill change them see if it helps. Thx

 

The idle was the reason i triec changing them in the first place but ur the 2nd guy to tell me that so i might go ahead and switch. Leaningvtoward fuel issue going to runfuel pressure test tomorrow praying its low. Easiest fix. Change filter and regulator 60 dollars and done. But have a feeling im not that lucky.

 

My Jeep started choking, we cleaned the iac and that helped. Besides that I had a hose running to my fuel cell that had a small crack in it, but I would try cleaning that area, it can gunk up over time.
