Rough Idle Issue! Please, Help!
My cherokee is 1999 2.5L Manual
Hi, I am from South Korea. Can't ask no one in here. Please Help me out!
the symptom is..
My Cherokee starts up just fine but after like 2 minutes as the RPM goes down to settle at proper RPM
it gets ROUGH... then If I press down accelerate pedal for 2 seconds it gets fine.
If I just drive right after start up then after like 50m driving, the car sputters. So I have to press down clutch pedal and press down the accelerate pedal.
this symptoms happens every time only after start up. (either cold start or hot start)
doesn't happen while driving.
I feel like some fuel line is stuck and it gets clean If press down the accelerate pedal..
please Help!

Make sure your intake manifold fasteners haven't loosened up.
Clean your throttle body and Idle Air Controller.

Just Did it all. But the symptom still remains.Should I take off the whole ground wire and clean it? I only cleaned the surface which connects to the firewall.Wire itself is pretty green as corroded.This would be shown on scanner? Should I just go to a mechanic?

Everything needs to be free of corrosion.
