Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Is the problem only at idle and it seems to run ok in gear?
Do you have a check engine light illuminated on the dash?
If so, we will need to get it scanned for troubled codes to really nail this one down.
The gas pedal has no effect? That could be either a bad throttle position sensor or accelerator pedal position sensor as well.
I don't think it's the air filter. It doesn't have a fuel filter, and the fuel pump rarely will let the vehicle start at all if it is bad.
The first step will to be to scan the computer for codes. Otherwise we would be checking/replacing things that won't be necessary.
You will need an obdII code reader. Some parts stores will loan them out. If not, most of them sell them.
You could also order one from somewhere like amazon. A basic code reader should be enough to give us an idea where to start looking.
A repair shop can also scan them for you, but they typically charge at least 1 hour diagnosis and you would likely have to tow it there.
I just wanted to check whether you still need assistance on this one.
Please let me know if you need additional info.
