I made some hard runs with my GTECH and heard some detonation. Next thing I know, the car is idling weird and it shakes a lot at idle. This happen to me last time I blew my motor, but before I didn't have ANY power left at all...could barely get to 60mph in 30 seconds. But this time...it shakes up till about 3000rpm, then it smooths out again and I have power! What is WRONG or what BROKE this time?

 

game over, dude.....again

 

One of 2 things..
#1 - You blew off a vac line or the TID came loose..

#2 - you blew your motor

Chances are you blew a seal in one of the rotors.. funny thing about a T2 .. it's actually possible to drive the thing on 1 rotor and still make good power when boost kicks in ..

If you decide to drop in yet another motor, perhaps this time you'll realize to quit tinkering with it until you know how the car works (and to be brutally honest, while there is some okay inforatino on this board, there is a ton of misinformation as well.. I would never use this place as my sole refrence)
