Yes it's a 2.4 and the code was p0014 it said exhausted B do I changed it yesterday and it still does the same thing

What's the code now?

My intake failed immediately after I fixed the exhaust.

Mass air flow and it was somthing else fail too I gave up lastnight I worked on it late today when I get off I will locate and change the air filter and maybe clean the throttle body I'm really lost on this one. When I start the car the t/c light is on I put it in reverse the light goes out but it still bangs in gear when I put it in drive it comes back on and it bangs if I reset with the computer the car stalls but it starts right up should I change the intake cam solenoid too

Well you have to be interested enough to help us help you. Give us ALL of the details. The codes will tell you what is wrong, don't throw parts at the problem blindly.

The search tool at top center of every page here will help you find how to do most everything on your HHR.

Ok Thankyou when I get home I will put the computer on it to get the exact code

and while getting the code(s), do a quick check on the connection for the MAF (the connector on the intake tube)

Ok I will thanks whopper thanks guys

Hello guys so I changed both exhaust and intake cam solenoid and the light went right out the banging stopped do when I changed just the exhaust cam solenoid it banged today I changed the intake and it took care of the issue thanks again guys I would recommend changing both at the same time it cost me $84 for both

We always recommend change em both, while you've got your sleeves rolled up.

Got my GM solenoids in last friday. Both seem to be exactly the same, grey top, and black top, just wandering what the $2.32 difference is? Not that I care, just wandering? Amazon, $67.43.

Stopped by AutoZone last week, ask the guy about them, he said 'what's that? Nothing, never mind, forget I walked in. But, That's typical of AZ, I just want to know how the hell, their stock, sells for more than Apple?
