Or it could be that the engine is misfiring, do you notice any performance loss? _____________________________ quote: ORIGINAL: pilsenblue Even tho My car looks great It will never be fast.

That oculd be the cause of the loss fo perfoprmance and shuddering. < Message edited by Sebba -- 10/13/2006 6:51:20 AM > _____________________________ (in reply to work ahead of me) Post #: 4
