Question about 1992 Toyota Supra
I have a 1991 Toyota Supra, 2.5L twin turbo, 1JZ. It does not have a problem starting but when I start it up in the morning and when I give it gas it will start to stall going down to about 200-300rpm. After about a minute or two of doing this and with me trying to get the rpm's up it will blow a lot of black smoke out of the exhaust. It also does this randomly when I am stopped at lights and when I give it gas. I have already had the idle control stitch replaced, as well as the computer looked at. But no matter what I do it will not stop stalling out. Any help would be much appreciated.
Piston rings are shot and your valves need to be replaced
have you been racing this vehicle or has previous owner
if you just bought the car im sure last driver had it semi decked out now you will need a laptop the cars software to reset vehicles computer back to factory settings
when owners drive there vehicles they set them up in a way so more gas and throttle can be applied you just need to reset everything back to factory settings on comp
and if that dont work you will definatly need to do an over haul

If its not a modifacation within the computer (from pervious owner) have the catalytic converter check for clogging and also the O2 and air flow sensor if so equipped, but don't forget the EGR valve.
