I am running extremly rich. Its so rich that the idle is at 300rpms. If i give it gas it will stumble till about 3k rpms and than after that takes off fine till redline. I dunno what it can be and i have checked for boost leaks and there is no leaks. I dont understand why it would do this. It is a stock 2g with a hallman boost controller and 14b turbo. I was doing a 3rd gear pull and i heard a loud pop and it started running shitty.

I am open to suggestions thank you!

Yeah its deff running rich because I can smell it and my a/f guage reads rich pinned. I do not havbe any transportation to get or any money to make myself a intake checker.


I also have a video of it "running" but i dont know where i can post it so every one can see it!!

I would also replace your O2 sensor if it has more than 60K on it.

Exactly. The sensor has to be toast(I mean 100% DONE) for the ECU to notice and flag up. via- CEL.
Usually when your O2 sensor goes, the ECU ends up guessing. This guess happens to be an overly Rich "Guess." Therefore that could be a reason you could be running rich.

I aso have to floor the car when cranking to get it started and I rechecked my check engine codes and it read p0100 a maf or vaf code. I know my maf works but is my wiring messed up? or is it my coolant temp sensor thats F#$@ed? also hear a rapid clicking sound when i turn the key to OFF. it will click maybe 10 times really fast. What is that?

Okay I followed the directions I think it was from dsmtuners.com on how to make the boost leak tester. I made the hole setup and put it on my turbo. pumped the system up to 15 psi and it held it for a while. I only had the one leak at the cheap 2g bov. I have already ruled out my hole intercooler and bov and upper and lower IC piping because i took a pipe directly from the j pipe to the intake elbow. I took out my O2 lastnight and it looks fine but idk how to tell if it is bad or not.

Okay went back out and ran it for 10 mins and pulled a P0100 MAF or VAF circuit Malfunction, a P0110 a IAT circuit Malfunction, and a P0115 Coolant temp sensor malfuntion. What one of those is causing my problems, I think its the coolant temp but what do u guys think?

Well it has to be maf wiring than right if so where would i find a wiring diagram. I also dont think its maf because if it is it has to be wiring for the maf and i was driving the car when it started running shitty. I think it is a part itself not wiring but idk ill check into the maf.
