cylinder 3 missfire?
Sunday, August 17, 2008 1:30 PM
ok. i got a 97 cavy daily driver. we have replaced spark plugs, wires, injectors and so far nothing has been able to fix this missfire.
it stalls out when you come to a stop sigh. runs really bad. just wondering if any of you had some info. would the coil cause that.?
but then i thought if it was a bad coil wouldnt 2,3 both have a missfire on them? well any input would be awsome. thanks

yeah. replaced the injectors new coils. hooked it up on auto tap says its missfiring in C3

weird thing is this started after i changed fuel pump/filter. so its just weird.

you may end up having to break down an take it to the dealer? I would hate for it to come to that, but if things dont start looking up for me, i guess I will be eating romen noodles for a month so i can get this solved! Haha!
