I'm having a disagreeable problem with the next symptoms:
* When the motor is cold, the Exp runs normal.
* When the motor is hot, especially in a traffic jam, the Exp start to run roughly, "RUMM rumm RUMM rumm", I feel the Exp increasing to jump, and after a pair minutes the engine shut off.
* The problem is more noticeable when I turn on the air conditioned.
* I avoid to shut off the engine by shifting the trans to Neutral (It was in OD). With this, the "RUMM rumm" is reduced, but it is still there.
I have made a search in this forum but the problems I have found not match exactly, but I'm thinking the problem is the IAC or a bad spark plug.
Do you have any comments or a suggestion about any bad component that help me to diagnose and find the problem ?
Thanks for your replies!!
