Hi guys,
Signed up to pick peoples brains on this issue I developed yesterday on my hhr SS.
Had a 15" snowstorm yesterday and had a 30 mile drive home. Ran fine until the last 5 miles of the trip. Was at a stop light and noticed the choppiness of the idle. Made it home but had a mild "buck" randomly under load.

Symptoms:

Choppy idle
Smell some raw fuel out of the tailpipe
Check Engine light
*nornally get 25 mpg average on the display. Getting 10.4

Figured a sensor wire got unplugged by the heavy snow, so I jacked the car upand inspected and came up with nothing.

Anyone have any clues on it. Appreciate it.

 

Check Engine light will give the code we need to help.

the last time mine did that it was Canister Purge Valve Solenoid

cost 13 bucks and 5 min to change but you need to get the code

 

Thanks for the reply.
Will an autoparts store do a code check for you?

 

yes most do

 

Great.
Ill give it a try and thanks A LOT for your help!
