once again i need help

[white_s14]

for awile my car has been having like a miss fire and i can find out what it is plugs wires new. idk if anyone has had this happen but when its doing this car bogs and black smock goes out the back??

[I RON DON KEY]

at least it sounds nice with a loud exhaust. loL.

[white_s14]

yeah its sounds bad ass and when u rev it to keep it from dyeing you some times shoot a huge flame lol.. but i really cant figure this out, and when u are going to a stop it will die, are if you going like 40 and hold the clutch in it will sometimes die,

have u timed it?

[S14Tech]

Time it yo, use my timing gun!

[white_s14]

ill check the timing rite almost positive (timing hasnt been messed with for a few months) ill double check.. what about the tps sensor? thanks guys!

[Nisxsz]

what about the o2 sensor? any oxygen sensor? You tried moving the distributor and see if it does anything?

[GriffinW]

well black smoke and bog = too much fuel. Try oxygen sensors and any other simple things that can mess up your fuel consumption.

[white_s14]

yeah ive done oxygen sensor ill mess with the timing when theres day light!

which cylinder is misfiring?

[white_s14]

to be honest idk, i just know it only happens after it warms up and your driving it will bog down and then comeing to a rolling stop it will sometimes die,, well as of today i messed with the distributor it idles better and dosnt bogg out i think any more but will still die when comming to a stop?? should i mess with the idle screw?
