Engine light came on today?

[JeRNuT]

I just got my car back from the dealership. They said it was throwing some wierd codes at idle. To fix it the replaces some silinoid in the intake manifold and the o2 sensor. this corrected the readings at idle. the light has not come back on yet.

this sounds just like my problem, and ive had the dealer looks at it, and they say i have a bad os but they did not replace. i had my injen on for about 4-5 months before it started to toss codes and the code is "too lean". i went out and bought a obd2 scanner and have it hooked up to my laptop and i can reset the cel when ever it comes on. I think im just going to buy new os2 sensors from the dealer and put them on my self

Went to Autozone and it read multiple spark discharge so I am changing the pluggs then I will check the wires if thats not it then I will try the coil. Hopefully its just the pluggs.
