Yesterday, my truck started running very rough and even the engine was shutting off at stop lights. There was terrible hesitation and lunging of the truck with very little power.
The service engine soon light is now on.
So, this morning, I press the OnStar button and tell them to diagnosis it. They pulled 3 codes.
P0101 - Engine Transmission System
P2270 - Emission Control System
P2272 - Emission Control System
She said this was related to the air intake system. I though to myself....oh no...I installed a Volant CAI 3 weeks ago.
After the call, I opened my hood. Lo an behold, the 3" tube came loose from the Volant filter box.
This means that my engine was sucking un-filtered air.
I proceeded to get the flex tube mounted back on the filter box, and now the truck runs fine.
However, the SES light is still on.
Question: Have I done any damage by sucking unfiltered air into my engine? It ran like this for ~50 miles.
How should I handle this? Take it to the dealer? Or take it to AutoZone and have them reset the light?
Advice is appreciated.
