I advanced the dizzy all the way and it fixed it for a couple days. I cant think of what it is. Valves maybe i dont know please help.

Give as much info as possible and make sure to add something tomorrow (reply) when more

it backfires pretty much all the time. more when i hit the gas. im not super good with cars so im not sure what alot of shit is called yet. Uhm i also made sure that the firing order was correct. 1342. i might be able to take a video of it making the noise when its sitting in a parking spot if i can get some help.

you need to double check your crank and camshaft timing.
how is the fuel mileage?
maybe your injectors are leaky

are you sure that the spark plug wires are in the correct locations on the distributor cap? - the DOHC ZC is not the same as SOHC

SOHC:
3 4
1 2

DOHC:
1 3
2 4

Yeah I'm sure the wiring is right. I actually used that picture to check a week ago. Lol

Why does everyone give up on my threads so fast. i get like one reply and then nothing lol. Anyone know a more active forum?

Fernpatch · 07-03-2009, 12:43 PM

what distributor are you running? Have you moved the cam position sensor at all? I had a problem like that about a year ago and it was an electrical problem with a splice under the intake manifold. If I can remember more details i will post again later.
