Hey,

My 99 Altima has a really bad idle...it feels like its going to turn off but it doesnt. The check engine light is on. I have done a major tune up, and recently changed the MAF sensor and it still running bad. I have sprayed the engine looking for a leak and still nothing. This morning i found that if i turn on the heater the car runs great...:banghead:

Any suggestions would be greatly appreciated!
