Then displayed '' Engine power reduced''.

My Aeroforce gauge recorded the CEL as 00335

So here's the curious part of this: The boost pressure goes much higher, and the engine seem to be much stronger, and seem to skip a little.

Any idea of what the problem could be?

This morning, i washed the SS, and after the wash, i went for a half hour drive. I then went to the dealership to take a look at a new Cobalt SS that's just arrived, turned off the emgine. Then i started the engine. Engine did not start right away. I started again, engine came on, and the CEL came on.

 

Not much help brother canuck, but maybe the HHR was jealous of you looking at the Cobalt.

 

Maybe that's it.

Christine, calm down.



I'll call tomorrow to make an appointment with the dealership, as there's a few things that i would like to see fixed:

1: Find the cause of the CEL, and fix.

2: When the car is first started up in the morning, the brake pedal needs to be pushed very hard to get effective braking.

3: The rear seats are very difficult to get locked back in the up position, after they were folded. I have to sit and push the seat with my back to get them to lock. This should be an easy fix IMHO. Probably just a locking mechanism adjustment.

4: And while i'm there, i'll ask them to check the intercooler/turbo fittings, to make sure they're tightened correctly.

2:

 

Rear seat locking in my '06 hhr and '08 hhr ss are just a firm push to get them to lock. Both were the same.

 

Ok, so i took the SS to the dealer today to fix the CEL P0335. The tech reflashed the ecm with new software, and resetted the CEL. So far, all is good, and the CEL did not come on after the reflash.

As for the vacuum brake fix, they didn't have the parts, and will have to order them from the U.S. They will call me when they get everything they need to do the job. They told me that might take two weeks to get the parts from the U.S

They told me to figure 4 to 5 hours for them to do the job, as it's the first time they will do this kind of mod on a HHR SS. The tech also looked at the intercooler fittings/tubing, to make sure everything was tightened to factory specs, and eveything was fine there too.
