misfire..... again
well it was the egr before and its been disconnected lately just so it would run right. well when i went to crank my truck today it wouldnt run right at all and mis fired worse than it used to. i had no choice but to hook the egj back up, that truck jerks so bad going down the road i couldnt stand it. i scanned my codes and it showed my egr was diconnected (duh) but it also said misfire on cylinder number 4. so im guessing ill but a new egr and get plugs and wires. idk what else i can do.

Loose the K&N intake, and throttle body spacer. Then clean your MAF sensor, and connect the EGR back up. Then disconnect the negative battery cable, and touch it to the positive battery cable for a few seconds. This will reset the PCM. You may still have an EGR problem, but it might be coming from the DPFE sensor.

theirs the problem! you will have to take the heads off and get them checked at a machine shop have them flow tested mine was the drivers side head. i done all the work my self but still had to shell out 400.00 for repairs

well when it gets back from being painted is there anything i can check to make sure thats the problem? or is that pretty much all it could be?

4.0 OHV's are famous for misfires on #4. It might possibly be a head or head gasket problem but there is a much more common cause. Often, a leak in the gasket between the intake manifold and the head will allow coolant to be sucked into #4 intake runner and cause the misfire and coolant loss.
