ok so i just had the oem clutch put into my 01 gsr,when i brought the car into the mechanics the engine ran like a champ, now the engine is throwing codes and misfiring really bad. never did that before i brought it to these people to do my clutch....what did they do to my car?????? loose connections?? HELP!!!

 

Pull the codes from the ECU. It will tell you what is wrong.

 

sounds like someone came up on some gsr parts.

 

turns out i had a burnt exhaust valve, must have been a weird coincidence with the clutch getting replaced almost exactly the same time.
