alright I have a 2001 1.8t and im having problems with it. the car was running with a huge loss of power and i am un able to figure out what the problem is. im getting a boost preasure loss code and a random missfire code. I replaced the n75 and the deverter valve thinking that was the problem, with no change I pulled the turbo thinking that was going to be my problem but that wasent eather. so with that said im kinda stuck. also im thinking if I have the car pulled apart this far maby i should do some minor upgrades the car witch has 100thousand plus mi. so im going to change out the turbo anyways even tho it is in working cond. any help would be greatly apreated, thanks
