ok heres the prob, bought car it didnt start so i went ahead and changed all ignition sensors, both crank sensors and the cam sensor also changed icm wires and plugs, car started and ran perfect but was lacking on maintenance like decarbs and no oil change in fifteen thousand miles and air filter was black sooooo, i ran a decarb with seafoam through pcv line at front of intake and it helped a great deal so after running a few more days i cleaned throttle body ran another decarb and put a flush in the oil system, all was going fine then when starting it back up after five minutes like bottle says it backfired once but that isnt unordinary so i didnt worry, revved fine in neutral so i ran it until no more smoke came out then killed it and went to bed, the next day i started it and it puffed in the intake but started and now its idling rough and misfires horribly through entire rpm range under load and i get like 11 mph. thats my prob any help is appreciated, btw ive already taken all the sensors back out and cleaned them so i know a piece of junk isnt messing up their signal unless its on their stators which i cant get to.
 
is the check engine light on and if so what is the code?
