You've assumed its ignition to this point. Misfire can also be a lack of fuel at the proper time, a lack of fuel, spark not at the proper time, too much air, a burned valve, etc etc etc.

I really dont know what to do, i thought the timing chain but how would it get off if it was never touched!?!?

like old lady tits

chains over time sag

does the car rock durning idol?

yea it rocks pretty bad and lags when i get on it!?!? So the timing chain would be a good cause of the misfire? what about the lag??

try fixing the chain first and see if it still lags.

ok thanks man!! ill get back in a few!
