Buy a Cobb AP right now. It's terrible for these cars to run with those mods an no EM. The AP is $695 and will save you a lot. Also are you sure your car doesn't have a aftermarket exhaust?

Please allow me to chime in.

Step 1: Ditch the bov and put the stock bpv back on. ASAP.

Step 2: Take off the aftermarket intake (for now) and put the stock intake back on.

Step 3: Take off the front mount intercooler and put the stock TMIC back on.

Step 4: Get the Cobb AP.

Step 5: Come back to the forum and we will guide on.

I hope the moron who owned this car before you didn't doom it for good......because they went with all the WRONG mods..........so sad.

That code is a "somethings wrong" code and doesn't really pinpoint what the problem is. I would be willing to bet you have a leak somewhere in your intake system i.e. fmic piping.

That being said you need to get your setup tuned if isn't already.

If, for some reason, you want to keep the awful mods on the car, go to a tuner immediately and have the system tuned for them. It's going to be the cheapest method assuming you can find a tuner who actually WILL tune the car with those mods. Otherwise, returning it to stock is going to make it much happier...Assuming, as was said, that the car hasn't been harmed by the current mods.

A COBB AccessPort is an engine tuning device. In your case, I do not think it will offer much help. Your mods are not conducive to using one of the off-the-shelf engine maps on the AP.

Have your car professionally tuned or return it to stock. My $.02.

Check the Classified Ads on this site to see if someone is selling the stock parts you'll need for the car.

Also post a Parts Wanted ad and see what turns up.

You might find a very cost-effective solution for acquiring the stock parts in very good shape.
