Jerking, rough idle & engine codes

[JohnnyBravo]

In March, my car began jerking at idle with flashing check engine and steady traction light. Dealer replaced spark plugs and coils and the problem seemed fixed. Few month later, I had the same symptoms came back briefly but no codes. This week, it jerked again and the traction light blinked while braking, it is now showing P0171 and P1101. My dealer's inspecting though, so I am hoping it's covered.

Got a P0171 or P1101 code? It probably means you have air leaks or your MAF sensor is dirty. If your car's jerking and the traction light pops on, it could be an unstable idle thing. Since you're under warranty, let the dealer take a look

@stopgoking22 I was thinking the same. The MAF sensor or maybe even a cracked intake hose. @JohnnyBravo Hopefully, your dealer doesn't try to wiggle out of the warranty fix. That's the BIGGEST issue you'll face ever, honestly. Claims for your warranty. LOL.
