Ok, I tried googling around for this problem but i can't find any info on it.
I have this weird erratic idle when i am at a stop light. It acts like it wants to stall and some times it almost does but the amp guage goes down to almost a quarter and it seems it's trying to keep it alive that way?
The weird thing about this is that it's very random, it happens maybe once every two weeks.
The idle is fine when cruising at high speeds, but i noticed that the car will no go into overdrive, and when i let go of the gas pedal, and i put pressure on the pedal i notice that i have to push harder than normal to actually get the gas into the engine; it's not a fluid motion.
I just had a tune up, and I am due for an oil change. I had the SES light go on and a mechanic scanned the system and said that my car was misfiring big time on 1 and 6. This happened after the tune up so he suspected that the coil packs needed to be replaced, which were.
I get no SES light, and the only difference i have noticed is that I was late for work so as soon as i started the car up, I put it in gear and left... it was idling fine when it was cold.
I read that people had similar problems with the IAC, I owned the car since nov 05 and it has an AC Delco battery which still says it's good according to that little green dot.
I'm not a car person, but i like doing my research and try to figure out what to expect, plus i like to keep the mechanics on their toes to make sure they're not giving me the run around. Anyone have any idea what this could be? I am willing to bet that if I went out there to start my car up and let it warm up it will run and idle fine.
Thanks in advance!
