Thanks in advance for any help. 2010 HHR LT 2.2 73,000 MILES.
1st-CIL-Missfire cylinder one
#2-when running the AC, when i come to a stop, it idles fine for a sec or two, then the check engine starts flashing, at which time the engine starts spuddering. turn off AC, all is fine. only does this at stops, works great on the highway.
#3-The hard shifting, service traction control, service esc warnings. Which i have been reading on and seems the solenoids seem to cure.

Any advice? Yes Iam cheap or I would have already taken it to the dealer. But from what ive been reading, they've excluded most of the cures from the powertrain warranty.

THANKS AGAIN

 

Take it to your local auto parts store like Autozone, Advance, Napa, etc. Have them pull the codes and then post the results up here when you get them.

Without the codes its a crap shoot, and too easy to change out the wrong parts which leads to unneeded spending.
