Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Im cam and ill try to help you in the right direction.
HAve you had a look at the throttle body yet?
These can bind up , since you have a scan tool you can look at the tp voltage 1 and 2.
you can also try a throttle body clean and relearn since you have a scan tool (if it has that feature).
let me know
thats what came to mind at first, but your theft light isnt flashing.
the 30 min "ignition on" relearn doesnt always work either. some of these have a scanner initiated 10 min relearn only and the conventional method doesnt always work.
awesome.. let me know
