Customer Question

2007 cts misses at idle. The purge solenoid was bad and now replaced. Still misses but no where near as bad. Could this clear up after driving for a little bit? Could having put 87 octane instead of 93 octane fuel in cause this?

Hello Im Chris and I can assist you. Lower octane could cause this problem but to be sure Ide like to scan the car. Do you have a scanner?

Expert:  CHRIS ZAPANTIS replied 10 months ago.

Also can you read data on the scanner? Can you reset adaptives?

First time it threw a catalytic converter code. That was erased. Then it threw a misfire on number 3 cylinder. Now today it's back to rough idle as bad as it was.

can you scan it and give me codes? I would also need fuel trims at idle.
