Use carb spary to clean out the throttle body right at the butterfly plate.you will see a lot of carbon buildup at the plate at idle.
the tbi should be very nice and clean there.
the carbon blocks air flow at this spot when the plate is at idle.

What would cause 93 chevy c1500 rough idle smells of excess gas at exhaust


Does the truck seem fine when you first start it & then acts up when it reaches operating temp?
That would lead me to look at my oxygen sensor, a bad sensor can cause the truck to run "rich" which would explain the fuel smell in the exhaust.

Rough low idle and black smoke


Bad carb or fuel injection issues- the system is fuel rich (black smoke) and also fuel rich system can make the idle low. Many things can cause this but thses are just a few.

Engine miss ,running rich ,-rottten egg smell from exhaust ,new plugs and wires,68000 miles 4.3 motor


It sounds like it may be your O2 sensor because if it is not working properly, the engine cannot determine how much fuel to ingest which would cause rough idling.
  • sometimes a bad 02 sensor causes a fuel smell from the exhaust, or you can just remove and check the sensor. if its really black "like charcoal" you might wana get it changed, also checked the wires on it and make sure they're not torn or anything. have scanned to find problem code if check engine light is on. good luck!!

Rough idling, poor gas milege


Usually the rotten egg smell is a clogged CAT. Is the engine light on and if so did you retrieve any codes?

Running rich, smelling rich


You may have a bad fuel injector or in need of a tune up badly. The early fuel injection (throttle body) had a single fuel injector that would clog and not spray fuel in a mist but would dump fuel. Does it run rough at idle? That is a good indicator. Some are rebuildable but I would suggest replacement. If you have not had a tune up in a while that should be done too.

83 toyota p.u. 4x4 running rough.


I think you must have the carburettor plunger not going well as you are getting flat spots under sudden acceleration, I think the best way to go is to get the carburettor overhauled.
