Why is a very strong gas smell coming from my tailpipe?


White smoke is water vapor and in this cold climate it is normal. Strong gas smell is not normal although you may smell some while engine is warming up. Bad cat converter can produce smells, but usually more like rotten eggs. If engine is running rough and seems rich, check coolant temp sensor. Bad converter can cause stalling too. Otherwise, idle speed is controlled by idle air contol motor which can get dirty and stick. Any codes set?

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.

Runs but wont idle. smells to rich. other than that it runs fine


This sound like a vacuum leak... Look carefully for loose/cracked hoses and connections from the fuel distributor/air box to the throttle body and around the idle enrichment bypass hoses... and also the intake gasket itself. The reason it smells rich is that the injectors are firing more to compensate for the lean running condition. It you run it this way too long it will overheat and warp the head or **** a valve... Hope this helps...;-)
