I got a 93 coupe 5.0, and the car was running fine in the morning. I took it to the muffler shop to get exhaust put on and when he finished I go to start it and it' starts but it acts like it wants to die out. So I'm driving it home and there is no power whatsoever and I have to keep the idle high so it won't turn off. I just change the plugs re-did the firing order an still is messed up. Anyone know what can be wrong?? Any help will be appreciated.

go and see if your o2 sensors are hooked up.

Unplugged all spark plug wires from spark plugs and dist. and reconnected them according to firing order post from this tech talk, ( 1,3,7,2,6,5,4,8) unless that firing order is wrong

You know.. A while back when I intalled some headers on my car I started to get a misfire top end.. I could never figure it out. I still have a misfire and its been like an year and a half, its just moved from top end to low end. Its there when Im crusing (1,900-2,300) but gone when im in it.. Wierd.
