I've got a 92 camaro and i was wondering.. my car's been running really rich.. when i rev the engine.. the exhaust smells like gas.. please tell me there's a simple fix to this if it is indeed a problem.. also it emmits smoke from the pipes.. it's more black than white... and from what i undertand white would be oil or running very lean.. but then again... i could be wrong.. any help would be great..

 

What have you done to the engine? If nothing, you may have a sticking injector.

Black smoke is fuel, blue/black is oil, white is lean or coolant.

 

no mods to the engine.. it's been like this for about a month now. the only work that i've had done to it would be the exhaust system.. but that was a while ago..maybe 3 or 4 months.. didn't think about the sticky injector.. what's a good quick fix for that.. i really don't have the money right now to go and replace all the injectors

any ideas would be great.. also.. about every 2 months i get a bottle of fuel injector cleaner.. maybe it's not working?

 

First you would have to find out if you do have a sticking injector.
If you have a fuel pressure guage it is easy, kinda.
Hook up the guage and pressurize the fuel system by turning the key on, watch to see if the pressure drops off. If it doesn't drop off then all is well with the injectors. If it does drop off, clamp off the rubber fuel return line and turn off the key for 30 seconds, then turn it back on and watch the pressure. If it drops off still then you have either a leaking injector or a leaking regulator.
Now the fun begins. You need to pull the fuel rails with the injectors still in them and hooked up to the lines. To do this you'll also have to pull the plenum. Raise the rails so you can see the ends of the injectors and have someone recycle the key again to get the pump to charge the system, look for any injector that is leaking, even if it just forms a drop on the end it is considered to be leaking. If none of the injectors are leaking, then the regulator is leaking internally.
