Have you checked to see if the distributor cap got wet inside? If there's water on top of the engine, it's probably a wet dizzy.

My first thought also, sounds like the dizzy got wet. Pull the cap off and get a hair dryer on low heat and high fan speed and dry it out for about 5 minutes. Post back with your results after this.

Sounds like a bad O2 Sensor. Have you tried looking into that?

o2 sensors are disabled its part of my tune specs.

ok well i would love to try it but i watchin my lil girl and mom not home at the minute but will try that asa-i can wit the dizzy.

so what is good idea to use to stop that from happenin again since the hood is vented?

Make sure the seal on the dizzy cap is in good shape. I've rinsed water over my distributor a few times and it's never gotten wet inside.

[90_f20b_cb7]

no water in cap.

went out to day to see if it was just a gremlin that would go away. nop. but its not doing it as bad now. it comes and goes.

new ideas?

[90_f20b_cb7]

BUMP!

where is every one?

[90_f20b_cb7]

ok so i replaced the cap and rotor just to see if i would help and no its still doin it.

ignitor then? where is that? in the cap? help plz i got have it runnin today so i can get to work.

why doesnt it need o2 readings? that determines how much fuel it gives the motor...

does it seem like it is lacking fuel or ignition? popping out of the intake?

[90_f20b_cb7]

it kinda acts like when you pull a plug off the dizzy. but not as harsh. its kinda sounding like a scobby with exst work lol.

[wed3k]

if you do that to each cylinder, is there one that doesnt affect?
