Yeah I am beginning to wonder too - although he may have two HHRs.
No mention of check engine light - which should come on with a p0301 code. and he didn't anwer the question I raised about it. I'm out |
OK, in your 2006 2.4 HHR , it was designed for AC Delco Iridium 41-103 plugs

Yes, I remember he has 2 HHRs.
Agree, it could be the non-ACDelco spark plugs. That's an easy theory to test. |

It is the p0301 that is setting the traction control and hard shifting.
After you do what Oldblue suggested you need to do a compression and leakdown test. |
Go to your "User CP" and set your notifications.
|
When you pull the plugs to do the compression test, double check them for differences between cylinders

Check this thread and it's suggestions - https://www.chevyhhr.net/forums/gene...d-shift-59930/
It sounds like a hub problem, but to determine which one you need to use a OBDII code reader that will read more than just the basic engine codes - some suggestions are in the above thread. |
