All,
The ol' HHR has a bit of a cold/Low RPM stumble. Other than periodic oil changes, air filter and cam position sensor replacement, there has been nothing done to this car. Should I throw a set of plugs and injectors at it? Once it gets up in RPM's it runs alright. No error codes.

Thanks,

Cam

 

I would not throw a set of injectors at it but the plugs are in order at that mileage. You might be surprised to find out that plugs is all it needs.

Plus check your brake pads for wear, and adjust your rear drum brakes (3-4 free clicks on the emergency brake seems to be the optimal adjustment). Also check the serpentine belt for cracking and wear.

 

Good call.

Note to self.....check belt at next oil change .
