Just Bought Used Cobalt, Already Having Problems
Well, it looks like I may have really messed up. I just bought a used 2009 Cobalt LT from Herts Rent2Buy, 34500 miles. I got three things fixed before the 'bumper to bumper' warranty expired at 36,000 but now at 36,400 miles the car has begun to miss very badly. At idle it will sometimes miss so strongly that it feels like it will die, but it doesn't. And it seems that the car doesn't have nearly as much power and pep as it should have.
I took it to the Chevy dealer here and they said that the 'powertrain' warranty didn't really cover everything in the powertrain, that "a lot of sensors and other things aren't covered.' I'm very skeptical of taking a car to the dealer for repairs, they tend to just start replacing things till the problem goes away - and if the parts aren't covered, I could be in for some expensive repairs. I checked with Herts (the car has a 2000 mile warranty from them) but they say that theirs is a 'limited' warranty as well.
I have a very good mechanic here, and am considering just taking it to him to see if he can figure out what could be wrong. But before I do that, I'm wondering, is 36,000 miles too soon for plug wires to need replacing? How about fuel filter? The problem started as a little hesitation and loss of power and has turned into a bad miss. I know it could be thousands of other problems, but those are the easiest I can think of. BTW, the computer isn't reading any problems - Anyone got any ideas of what I could check myself?
