Crappy Start/Backfire

[Dark_StRanger]

Hey guys,

On my 91 3.0 im getting a messed up problem where it will start then chug out a couple times, then when it catches it runs like crap for a while. Ill try to accelerate and it bogs/pops. like a really bad misfire. Its coming from the right bank from what i can tell. I recently replaced my plugs wires cap rotor MAF IAC PCV ECT(for the pcm). I highly doubt it but that sides exhaust manifold is leaking like a french whore(no offense). Any ideas?

Thanks
Mike

The exhaust leak prolly already has burnt the nearest spark plug tip off of it.. NEXT thing will be a burnt piston or a burnt valve... all from that one exhaust leak. FIX it today and then look for what damage it has done.

question, does your fuel pump run non stop with key on engine off?
