Now that you know your running rich ?


The next question is;
"How are you gonna (realistically) fix it before you spend all your hard earned cash at the gas pump ?"



Do you have a CEL on ? If so whats the code ?
You may have an 02 sensor gone bad or a stuck open injector.

[Dillon]

There is no CEL.... How would i check that other stuff. and it only dos it when i take off fast or rev the engine.

[REY04]

try replacing the O2 sensor. sometimes it does not work properly.

how old are the plugs? are they gapped porperly? are you sure you have all of your spark plug wires on all the way so you have a good connection? how long has it been doing this? is it since you have last filled up? if so you might have bad gas

[Spider]

+1 to all the above.
Also........
How many miles are on your injectors ? Are they original ? Have you tried an injector cleaner? (like Berrymans B12 or Seafoam)
When is the last time you changed your air filter? Has the car been sitting for a while ? (if so, rodents can store food and make nests in the airbox and/or in spaces that are prior to the actual filter.) Exhaust system clear ? Do you get a "rotten egg" smell from it ?

[Dillon]

I bought pre gaped plugs so idk if it would be them. And my plugs are all good. And the car drives every day. And idk if i would call it rotten egg smell but its bad haha

[Pir0]

Rotten egg smell immediatly sparks catylatic converter to me, is it only when you start the car this smoke appears? Or after you've been driving for a while? Driving hard/easy etc?

Just a side note here....

Some carburetored motorcycle engines (Kawasaki 4 cylinder engines for instance) use the same spark plug that some car engines use.

You can't assume that because a plug is "pre-gapped" it is gapped to your engine's spec's.
Always check gaps in new plugs.

And you have been ask a lot of questions.
If you would answerer all of them people would be better able to evaluate your problem.

Well on this type of plugs i have you cant gap them cause they have a halo thing at the end. Also it only smokes right when i crank it and when i accelorate fast.
