90 GT rough idle and no power
So i bought this mustang sunday it kinda idles, is really cold blooded, has no power at all a 2.3 mustang will spank this car. so far ive replaced plugs wires, plugs, cap and rotor, tps, and fuel filter. all these helped but it still idles rough and has no power. i also set the tps voltage to .98. the P.O. said he adjusted the timing but didnt pull the plug when he did it so im thinking i need to buy a timing light and set that. this car has so many problems i alsmost don know where to start after i get it running right.
any ideas on how to repair the floor cause the drivers seat is ripped out of the floor and i really dont want to pull the carpet and weld in a new section
