2011 hhr 2.4l struggles to accelerate until 2500 rpm
2011 chevy hhr 2.4l flex fuel LT
It boggs down and struggles to accelerate until it reaches 2500 rpm's then it takes off. It's as if someone flipped a switch.
It has a new throttle body, spark plugs are good and look good, new air filter, cleaned maf sensor and No CEL on. The air intake hose has a hole so it's getting warmer air but that's recent and it's been doing this for some time now
Thanks for the help
