Question new subscriber

Hello all. I am new owner with an issue on my 2009 HHR LT. 2.0 litre motor with 8th vin digit of B. The problem is every time I drive, it stumbles at steady speeds of between 35 to 40 mph. Rpm's are always between 1100 to 1300. No check engine light (and yes it works) is on and no codes are stored. It is almost as if the throttle position sensor has a dead spot. Need some feedback please, the dealer of course finds nothing wrong.

to the forum mcsean!

B = 2.2L LE8 Flex-Fuel engine on a 2009 HHR.

Sounds like an issue with the TPS or the throttle body itself, odd that it hasn't set a code though.
