Still having boost problems, besides the P2261 and another MAF code I have had, can't remember the number, on Friday night tried to get into it a little bit, it hit boost then gave me the P0234 overboost code.
The Forge BPV will be here tomorrow, but today I took out the Dejon spring and put the stock one back in, to see if that would clear up the boost problem and also took out my K&N filter and put a WIX air filter in an attempt to bring down my LTFT's. Going for a test ride the SS stumble at first then cleared up. Tried to induce boost, it did then lost it. And the turbo blade sounds like it's squealing at times. One of the guys on the HHR forum had similar problems and it turned out to be the Wastegate Actuator. Needs your thoughts or suggestions and is this part hard to change out? Thanks for any info..................................Tom

 

In my experience the most common cause for your problems is a IC pipe that is loosely connected. It may pop off just enough to loose boost, screw up the MAS calibration and even give a BOV error since it acts like a BOV opening, then closing.

 

thanks for the info, but that is one thing I do every so often, is to make sure all of my connections are tight. I did tighten everything up before the test drive. Sometimes it feels like when you first accelerate, the boost is there, then you let off the gas and press down again, no boost. Other times you press down and you can't even get 2 lb of boost. And the turbo blade making noise started over a week ago.

 

G5 man, saw your neay doylestown, but where you around allentown on friday night, think you past me on rte 22

 

yea in for info as well..i doubt the pipe loose cause ive checked and double checked mine and none of them are loose ive even changed out my cold pipes and still same issue.

 

so how do you tell if its loose?..is it finger loose or is there something im suppose to do..i inspected it and its not finger loose so is there another test?

 

you may have me confused with someone else although I am near Doylestown I have a 08 Blue HHR SS

there are t-bolts on the air and IC pipes and some regular screw clamps in between, you need to use a screw driver and a ratchet to make sure they are all tight. If I remember correctly the t-bolt clams are 14mm. On the IC side close to the IC, I reposition the way that the t-bolt faces, so I could tighten it up from under the hood as opposed to under the car. They will become loose with all of the vibration under there, I always check them about every 5,000 miles or so.

 

im not talking about the ic pipes im talking about the actuator rod

 

o my bad, someone passed me on rte 22 in a turbo'd G5. I didnt see a car or anything in your sig, and by talking about boost, location, and pontiac, i thought there was a chance haha. GL

 

misunderstood.......if it's the part I am thinking about, it has two nuts that keep the rod in adjustment, they should be tight. can't think of another way to test......



no problem, I had the G5 before the HHR SS, maybe I will pass you one day....
