Having problems with your Chevrolet HHR ?

2.2 liter hhr bogs down at 5000 rpm

\015 If hard accelration is attempted the engine runs up to 5000 rpm then goes flat as if it were a wet condition. Backing off the gas resumes normal running. There are no codes being thrown and all other engine operations are normal. Even with this going on I made a trip into California and averaged 37 mpg. So this sitution is just frustrating\015 Posted / edited by AnonymousUser on : 20-11-2017
