'00 4.0 OHV #4 misfire
I cant remember what the CEL code is, but if i install new plug in #4 the misfire goes away for a few months. then all of the sudden its right back.
I have replaced all O2 sensors, fuel filter, plugs, added can of seafoam to gas tank. I'm thinking maybe its time to buy an injector. I have been doing some research, and someone said this may be caused by a coolant leak into the #4 intake where the manifold meets the head. has anyone heard or this?? Thanks in advance for any help
