Check Engine Light and Service Traction Msg

Please help... I just bought a used G6 GT 3.5 about a week ago with 43,000 miles. It ran good for about a week. Now acceleration is sluggish, hesitatant (jerky), the check engine light flashes and then goes to solid accompanied by the traction control light going on and off (and Service Traction message on the radio display). The problem is worse when I start from a stop (although I have encountered it all speeds). If I press moderately or hard on the gas, the problem appears right away.

Any help would be greatly appreciated.

Thanks,

Paul

I would think that the first thing you want to do is find out what is throwing that CEL. usually places like autozone do it for free. Then at least you have somewhere to start.

Thanks... I am hoping maybe it is a case of some bad fuel, but I have seen a number of similar postings.

Bought an OBD II code reader... I am getting a P301 Cylinder 1 misfire (no other codes are showing up). This is happening when I accelerate. Does anybody have any ideas as to what I should look into or check further?

Thanks,

Paul

Should be right below your steering wheel (near the hood release).

Engine light and traction control

Just got mine back from the dealer and they replaced 2 spark plugs and a wire. Apparently the wire was arcing. I was told that the traction control light comes on in conjunction with the engine light as a safety feature to the engine when a misfire occurs. It seems to be running fine again. To be continued........?

Thumbs up G6 service traction control

Good day Paul.
To get rid of this problem you simply have to replace you air filter.
This problem has to do with the OBD II code P0171 & P0174.
P0171: System too lean, bank 1. And P0174: System too lean bank 2
This means that your engine is not heaving sufficient air intake.
This is causing that the TC & the check engine light to come on and off.

Hoping that his will solve your problem for ones and for all
