Finally got a chance to drive the car today after sitting for a long time. My question is... the OBD II diagnostic is ON, I did not have this before I stored the car for the winter. Any input on how to check is really appreciated. The car have RandomTech Catback high flow exhaust that was installed two or more years ago and don't have any issue until today. I did the search and for some reason the search funtion would not find anything and/or kept saying that I did a minimum words
.
