boost causing bog
 

i bought this car with it having an issue. when the boost builds up it causes the motor to bog out. i have checked all the vacuse lines and the CEL ligh was on so i did the new TPS and both knock sensors are gettin switched very soon. now back to the engine. it runs great when the boost is not built up but ass soon as it does it just bogs right the hell out. where should i go now? i already went threw the vacume lines and replaced them all. im new to turbos and i need guidence.

boost leak somewhere? maybe cre can shed some light. have you searched yet?

my asshole is itchy.. cre can you hold this flash light and shine it. tell me if I have a hemorrhoid.

damn that shit pisses me off. Hey how about we just rename the forum to CRE please answer my questions.. obviously no one else here is able to..

could be acouple things. you said you were or werent throwing any codes? give it a check. make sure all your spark plug wires are secured. (snug) and I would check you're fuel pressure.
if your checking for boost leaks the most common areas are the Charge pipe right off the bottom of the turbo and the couplers at the 3000 pipe..
You said you just bought this car.. Did the previous owner do anything to the waste-gate to throw more then stock boost? allot of boost and not enough fuel will bog your engine down, running lean does the same.

i am having the same exact same problem! Need help. New to turbo engines

sounds like either a boost leak or over/under fueling. most likely under fueling unless your FPR is boned. then youd basically be shoving fuel past the injector pintle.

another possibility is bad KVAFM. check up on the TSRM to see how to test it, youll need a multimeter.

ohming the injectors wouldnt be a bad idea either while your checking.

just another quick thought, check to see if your wastegate is working properly

good luck!

i just pulled a code 52 so i am guessing that might be my problem?

wouldnt hurt to fix it..
