I just got a 08 Cobalt SS t/c.. and this morning while I was driving to class on my cobalt and I realized that my car was not getting any boost. I checked for any loose pipes, and I could not find nothing wrong. I would really appreciate if someone could help.. I got a check engine light on with the following codes;
PO299
PO113
PO114

 

We need some info. Does it have an aftermarket intake? If it does, is the pipe for it made of metal? Is your MAF wiring in good shape? Do you gave a Forge BPV or stock? Do you have any black smoke out of the exhaust? How many miles on the turbo?

I'm not saying its necessarily a turbo failure, but that's the most common failure I've seen for the 0299.

P0113 and 114 are both iat1 errors which is located in the MAF module.

 

Thanks for replying.

I has a stock intake, but it does have the rest of the pipes on Hahn brand with an aftermarket Hahn intercooler. I have already checked for smoke on the exhaust and it has no black smoke coming out of it.. apparently since the turbo is stock it has around 80,100 miles on it.. I am not to familiarized with turbo engines I just got the car it was working fine until this morning that realized no boost was building up..

 

You might want to to pull the intake tube off the turbo , put a camera down there, and take a pic of the turbo inlet. Post it.

 

I already checked the turbo and the turbine is stuck a bad turbo:/

 

Do you know of a repair kit for a stock turbo?

 

You can buy a used ko4 for cheap.

 

How much and with who?

 

300 and up used in the classifieds and eBay. Brand new from zzp I believe 600 or so.

 

oh ok thanks for the help I will look into it.. hopefully I can find one asap.

 

wow didn't you just buy this? sounds like the previous owner knew it was on it's way out and flogged it.

 

Probably I haven't even used the car much but o well I still have to fix it up.. if you know of any ko4 forsale out therem

 

Any body know of a good place to buy a turbo rebuild kit?
I have some pictures of a broken part of the turbo but I dont know how to upload them?

 

ZZP has a complete turbo set up off of a crate motor on ebay right now for $599.00

 

I posted pics on my album I couldn't load them on to the post..

 

It's not worth it to rebuild the ko4, just buy another one.

 

I have one for sale, Pm'd
