oh ya and he told me it was somethign to do with primary injectors, the stock harness is shorting out sumwhere or sumthin like that! bu ti neva had that problem b4!! hes was also like new stock harness is like 800-900 dollers, and plus labour and installing it woud be around 1500 dollers!! he said it be better if i get microtech off him cuz it would only cost 500 dollers more!!

No Cones

Not sure why no one has commented yet... check the most obvious thing first.... Boost Sensor (btw the intake elbow and the fire wall). Make sure it's plugged in and that the vaccum hose is connected. Pull the check engine code to see what that is indicating.

Yep, stock harnesses are not cheap.

And before your ! key breaks on your keyboard, you should get it fixed. If the harness is bad then that pretty much needs replaced.

You can find the ECU code procedure in the Factory Service Manual (check the FSM sticky thread) and somewhere in the FAQ (also a sticky thread). Keep using the stickies.

anythin else any1

scratchjunkie

are you telling us your car was fine before it went into the shop and you accepted it in worse condition than when brought in?

rynberg

Anything else? You were given the tools to diagnose the problem. It is apparent you didn't even try them. If you aren't going to try the solutions that people give you, don't waste our time by creating a thread!

It's obvious your car is in "limp home" mode for some reason. Checking the Code should tell you why. Then you can narrow it down to a small subsystem to troubleshoot.

sounds like he has done a twin turbo simplification mod,,,,, yes the unplugged sensors will trigger the dash warning light,,,,try compile a list of the codes and post em,,,lets have a look,,, have u tried resetting the ECU,,, ( i think u disconnect the battery for 30 seconds press the brake pedal and reconnect,,,,this may put your car back in normal mode)
