He is going to go get the codes read but just trying to an idea if yall do, its an 09 ls3 vette, a6. 7100 miles on it, barely driven and he busted it out this weekend drove to town everything fine untill he got bak in it, check engine light started flashing, low tire pressure, it feels like its cammed, just shaking at idle, service active handling and something else. any ideas? thanks

If it has been parked for any length of time the gas could be bad,which is probably causing a misfire and or knock, which in turn would make it run rough and down on power.

The tires are probably down on air if its been parked,refill them to 35psi,after a few cycles of driving the sensors will read normal and the light will go out.

yea im gonna have him bring it up to the dealership i work at and get it looked at, i just think its weird cuz he drove it a good 10 miles before it happened then got bak in it and it started doing it right off the bat. thanks!

No prob.


If its really hot and humid or unusually cold the tank can sweat.

Sometimes the alcohol in the new formulated gas (E85 for example, 15%methanol/ethanol) will trap water from the tank sweating and cause driveability problems.
