ohhh man. what a long night....so im driving along and all of a sudden i hear "POW" and my car shuts off....and it starts back up. oK. fine.....i get to the light and the car just dies on me and wont start. [ls/vtec ctr pistons bc3+ cams rc 310injectors] and so on. now....after about 20 or so tries....its start up like normal....runs/revs all fine. then just hesitates and dies with loud back firing. I THINK the backfiring is cause im running RC 310 injectors and its dumping fuel into a hot motor and just spits it out, and POW.


my question is what could this be? bad spark plugs? bad injectors? bad distributor? what is going on..im so mad and in such a daze right now.... the engine will not throw any CEL's for the 1-2 minutes its running fine. anyone think the motor is blown? car has new water pump / oil pump /radiator as well. the car was not over heatting either...

 

I can almost guaruntee its ignition related. Ill try and post more when i get off of work later.

 

was the first "pow" a backfire or did it come from the engine bay? are you tuned, I assume you would have to be but figured I'd ask? what have you checked so far...If nothing then I would start with cam timing and ignition.

backfire. untuned.

 

wow, hit the dyno before you destroy your motor. I'm surprised that it's running at what anyone would call "fine" at any point. That's a pretty voltile mixture you have there with that compression ration and engine management...or lack there of.
