Do a comp/leakdown test.

Your #4 injector might be leaking. You might be having a misfire in cyl #4, too. Then either will affect the O2 sensor reading causing it to run like crap, and an ignition problem will even affect the MAP reading, again making it run like crap. Of course, a mechanical problem will throw things for a serious loop as puppet suggested.

A basic series of checks will usually get you in the general area, if not to the exact problem. Check the basics first.

i found out wut it was my head is cracked

[xsaigen]

is there anyway i can fix that without buying another head?

[xrattiracer]

got a junkyard near you?

woa woa woa. How do you figure your head is cracked? Did you take it off? That was a real good guess if you didn't do everything else first. If the crack is between the valves, you've just wasted your time, as every TD head I've ver seen has that crack. Are you sure it's not the head gasket? Even if it was the head or the head gasket that dosn't explain the wet spark plug. Unless it's wet with water which you didn't specify! Cheap way to fix a cracked head? Go to the junkyard, spend $50 on one that isn't cracked, go to the machine shop with it, spend $200 to get it machined, go to the dealer, spend $50 for the head gasket and new bolts, then put it in. $300 and it will be right as rain.
