I apologize for the innapropriate title i wrote earlier and ask that everyone forgive me for letting my frustration have the better of me, now i will repeat my cry for help so as not to make anyone post in the sesspool of my anger that was my previous thread. I publicly apologize.




Ok, I'm pissed off to no end. I have not installed anything incorrectly and its just getting worse. Ok I had a boost problem where it seemed like the wastegate stayed open so i replaced the actuator with a high pressure one from BR. Sweet. Now when the car gets to one psi the whole car shakes violently and sputters and makes loud popping noises and stuff. I replaced a few things now the car sucks butt and feels like its going to blow up. I put in a walbro, BR FMIC, forge wastegate, and i re-routed my MBC from the turbo outlet to the boost line from the intake mani. (I used a Y fitting and ran one to the vac outlet on the BOV and the other to the MBC, while the other went to the wastegate. Maybe its a bad fuel pump, i don't know. I have to be at turbo trix on monday and I don't know what to do. Please help, or if you know of anyone in my area that can help please let me know. I'm at my wits end.

 

Step one, stop adding new crap. It's always tough to diagnose a problem when you keep changing the variables. It's always best to start at a known "good" point, make a change, and then test it out. If it doesn't work then generally speaking you know what part is screwing you up.

Step two, stop guessing and throwing new parts at it.

My guess is that you've got a fuel delivery problem. However, I'm not suggesting that it's your fuel pump. Where did you say you tapped in for a boost signal to feed MBC? Did you use the line feeding the BPV? That normally works. Did you screw with any of the lines feeding the fuel pressure regulator?

Have you checked to ensure that you don't have a massive boost leak that is alllowing metered air to blow to atmosphere? (although that would cause a rich condition) Do you have your MAF plugged in? The car will start and putt around fine with the MAF unplugged but will fall on it's face the minute you try to lay into the throttle. BTDT... oh, and in my case I couldn't see the CEL for the MAF since I already had a rear O2 CEL.

Basically check everything you may have touched. You've probably done something really silly.
