ok... i am new to the supra world so bare with me. I purchased a 1986.5 supra a few months ago. It ran horribly when i got it. I replaced spark plugs, wires, distributor cap. it ran better but when i start it I have to pedal the throttle to get it to get to idle rpms, after that it runs great. now when i start it when its cold it starts up no problem and runs and drives great, but if i park it and start it back up before letting it cool it sputters when the rpms get up to 2 grand wether im driving it or its parked. I have no idea where to begin o diagnose this problem. any ideas...?
