Question about 1996 Oldsmobile Bravada
I have already checked/tested the ignition module-ok. changed the coil pack. still runs rough. i checked the plugs, 2 are not responding. driver side rear, and passenger middle plugs. what do you think the problem is? a fuel pump, maf sensor, or something else. when i put the new coil pack in, no difference, still ran really rough. rumbling like a built 350. i then was running the bravada last night and found out the pcv upper boot was blown out. i changed that and it ran smoother. any help would be great, i have wasted my entire vacation trying to figure out what i need to do. well right now it is miss firing on the 5 cylinder and it is running very rough could you help
Check for bad spark plug wires or wires connected to the wrong cylinder.

on those amung other there is a wire from the module to the crank sensor it might have melted and be shorting out. make sure its not melted between the sensor and the module. they mainly melt after awhile.
