okay for the past month or so my 87 mustang hasn't been doing too good, the problem is that awhile back when i bought it, it ran pretty bad, i replaced parts to the car and it ran good. Battery, upper/lower radiator hoses, thermostat, exhaust manifold, pcv valve, air filter, water pump, after that it ran pretty damn good but i was scared of tearing the timing belt on the car so i decided to replace it, i checked it and damn that **** was bad, i got the belt and i did a pretty bad job in putting it on. I just marked the sprockets to where they were at and made sure they did'nt move, i put the belt back on without anything moving, it turned on but it just wouldn't go, I mean when i put it in reverse or even drive I would rev the engine like crazy but the car wouldn't go, only when I stepped on the gas in short bursts would it go but just barely even anything. Could i be out of time still? Or is it the
tranny?
