hi there guys i bought this 88 supra and rebuilt the original engine, and still having problems with the car. it has an automatic transmision which is oringinal aswell. first of all, when i start it up and press on the gas. it rev's up to 900 rpm and if I keep it reved up, it will move up past that point but only after 40 to 60 seconds later. why does it do that? and secondly, after i can rev it up to whatever rpm, i take it out of park or nuetral, and put it into drive. and I try drive away, well it moves so slowly forward or backwards like it is stuck in high gear and no power to peal out the tires, and i can't rev it to cause the tires to spin out. what is going on with my car??
