Ok, about 2 weeks ago my car started smoking pretty bad. Last week it started missing in low (1500-3000) rpms, and now I cant put my foot on the gas with out it missing and backfiring . I know that i'm back firing because of the missing. I took it to my dads work but they only fix fords. They checked my spark plugs to see if they were soaked in oil but they where not and they did not look like they were burning oil. They said it's a secondary miss fire and it could be the coil pack and plug wires. But they said, it was just a guess. what do you think???

The majority of these stuttering/misfire problems come from wires or plugs. Make sure you get the right plugs, gapped properly (check the search NGKs) and unless you're highly modified, you can make do with a $30 set of BOSCH plug wires from Autozone, but be sure to do both at the same time. That will make me happy.

I'd definitely replace the plugs, first thing. Even if they look ok, replace them. Once a plug fouls, it should go in the trash. I fouled two plugs and hence the engine was running on 2 cylinders. I was barfing grey smoke out the exhaust and "idling" at 400 RPM. Just replacing the plugs fixed 90% of the problem.

for the origianl starter of the post, i had the exact same problem. it would misfire 3-4 times in every gear from idle to 3k rpms. then after 3k rpms or so it would smooth out and run a lot better. also the idle was rough, and it smelled nasty. it ended up being a shorted out wire. changed the plugs and wires and all was good as new.
