Hey,

I have a 2008 Cobalt LS model that acts very sluggish. On the highway I can press the gas pedal and the RPM will decrease slightly and the car doesn't speed up...unless I really push the pedal fast/hard.

I have read another thread where it was suggested that the owner clear the ECU(?) and do a relearn.

I bought the car used with pretty low mileage. Does the car somehow remember the other driver? (relearn) It's kinda annoying to want to speed up slightly, push the pedal, and keep the same speed.

Any info would be great.

thanks.

Well, how many miles are on the car?

Are you still under warranty?

Are you getting a CEL?

I would maybe start by, cleaning the throttle body.

I if its high mileage, maybe look into a tune up.

Plugs could be foul, Throttle body is probably dirty and needs to be cleaned. Could be bad gas, A clogged fuel filter. Considering that our throttle bodys are electronically controlled then it could have something to do with that as well. Are any acessories on when this is occuring such as the A/C ? I know the A/C system robs our cars of horsepower big time. Anywhere between 7-12 Hp
