This is the 4th time its come back on. It all started when it started to miss at idle when sitting at a light. So I changed my plugs, helped alot. Ran fine, then started to do it again, the light came back on. So I replaced the idle air control valve, and I thought I fixed it. Ran great for about 24 hours. Then, I'm driving and it starts to miss while i'm breaking for a red light, when I get down to about 10-7 you can feel a little hesitation, or shake. I was like, oh no, and sure enough the SES light came back on. It's probably the same code, as the first times, which was that is was running lean on the passenger side. And yes, I've had the tuner add more fuel to the program on the chip. Anyone have a clue what the he!! is going on

what is the code? is it still a lean code? just a thought, check your hego wires? mine did exactly what you explained, hesitated while decelerating, but for some reason it only did it once and didnt throw a code.

 

what is the exact code? o2 sensor would throw a lean code

 

I don't remember what the code exactly was, but it said that I was running lean on one side. But, I was running very rich before, would that foul the O2 Sensors?

Clogged fuel filter---how many miles on it?

Dirty injectors?

Bad coil?
