misfire ok so i have had this misfire on my 01 ss 6 speed for a while i had been lazy as into looking into the problem but the car is really running like crap and it keeps getting worst. it usually happens when i start hitting around 3500 rpm...i changed the plugs and wires , moved his coils around to see if it was one of the coils but nothing still getting a misfire what could it be??? also checked the fuel pressure and nothing it was good.. i am also getting another code it is to a secondary air injection smog pump ... i really need to get my car running so anyone ??? my next step is going to do a compression test and check my injectors

Which cylinder is misfiring?
Swap that injector to another cylinder, if thats not it then swap that spark plug....see if the misfire follows them. That will find the problem.
Also, if a spark plug wire is touching an exhaust pipe manifold at all...it will cause misfires in the mid-to high rpm ranges. Also, make sure the sprak plug wire(s) is snapped on good at both ends.
