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

I had the same problem with my '93. unplug the mass air sensor and see if it get better. The idle will still be rough but the lack of power and throttle response will be back to normal. after that you can either clean the sensor or replace. Be careful cleaning it as it is a very thin wire.

I also have idling problem whenever my car starts with cold engine. I have the best plugs replaced the wires, It usually starts well but a couple of minutes later it starts to idle weird.
