Hi I got a 2008 HHR Panel that acts like its struggling to accelerate between 20-35 mph after that it seems to run fine i notice some fluctuation on the tach also when this happens i dont think its a shifting issue however i am not totally sure of it and since i just got this i hope its not a major issue i'm hoping there's someone else that's experienced this also i have heard that checking the trans fluid is kind of a pain also i did put some injector cleaner in also gonna try that one more time to see but i dont think it will correct it Thanks and its a pleasure to be a member oh gee poet and don't know it heheh

 

Welcome to the site, ok, an 08 panel , now which engine is it? This could be a dirty throttle body or MAF sensor, it could be other things.
Any CEL light ?

 

Hi wokbelly. to the forums!

You could go to your nieghborhood auto parts store, where they should read your OBD2 codes, at no charge. Post any codes(P0300, P0011, etc) up here, leave out any description they might give, they can be misleading. We'll do our best to help you out!

Some codes also have a suffix, be sure to include that also.

 

Its standard 2.2 not sure what you mean about the CEL light if you mean check engine or service soon light i'm not seeing that it does seem to struggle more when its cooler is its been here lower temps we been seeing here 10 degrees and lower

I am taking a wild guess at a transmission problem. Since that is the speed range of 3rd gear.
