88 Supra Questions

[finsfool53]

I have an '88 non-turbo Supra. I am having some problems with it. When I first start it up it is idleing rough and blowing black smoke. This problem usually stops once the car is put into gear and i start to accelerate. Over the past few days it has been dying out of nowhere either when just sitting idleing or as soon as I hit the gas from a stop. It appears to be getting to much or not enough gas. I was thinking it could be the oxygen sensor but any input that anyone has would be great. Im sure someone has had a similar problem or at least heard this before. I have had it in to a mechanic who couldnt tell me the problem....Alright thanks for your time.

does your temperature rise? cuz maybe your head gasket is blown ... supras are known for bhg

doesn't sound like BHG. No overheating, no loss of coolant, etc?

Maybe the IAC motor
