well ive checked every thing that ive seen to check after going thru forums.
i double checked my timing and it seemed to be good. well i went off the oil pump mark and cams are lined up. after tightening the timing belt and every thing back together its still misfiring and has a popping noise coming out of the exhaust. looking every thing over i noticed tdc on the crank pulley isn't lined up but the cams are. is tdc on the crank pulley suppose to be lined up ?

 

This does not directly answer your question but I had similiar issue this week. My misfire starting a while ago and got worse. Could hear popping in the exhaust almost like something was hitting it from under car. Then I got a CEL. My tps was failing. Swapping it today. May be worth a shot to pull out a multimeter to check. Wont take but ten minutes.

 

thanks ill check that today. but any one else know if my crank pulley mark should be lined up with the tdc line?
