Hi guys,

Need help here, as the Explorer is running like hammered dog doo and throwing codes.

Started with my wife driving, when the SES light began flashing at her. She limped it into AutoZone and they pulled a couple of codes, indicating that the EGR valve was not working properly and that the Crank Sensor was faulty, along with cylinder 3 and 4 misfire.

Soo... replaced the crank sensor, new plugs and wires over the weekend.

Car still runs like crap and is throwing the following codes today:

P0300, P0302, P0306, P0316

What to check next? The coilpack?

I've read in my searches here that cracks in the intake manifold can cause these codes to be thrown, but not sure I could track down a crack unless it's blatantly obvious.

Any advice you guys can provide would be immensley appreciated!

Much thanks, in advance!
