- 2000 Explorer 4.0L SOHC
It's been awhile since i've been on here, but my 2000 explorer 4.0 sohc has been good to me until recently. Just about to hit 306k and haven't any serious problems except timing chains (thanks ford for making us have to pull the engine) Now all of sudden it's everything at once, and I'm going to try and explain this the best I can. It started with codes P0455 and P0457 and the check gas cap light was on, so I replaced the gas cap, checked the filler hoses for cracks, and replaced both the purge and vent solenoids. The lights stayed off for awhile, but they soon all came back. Then my hvac started having problems. The air would stop blowing out of the vents and divert to the defrost vents when the engine was under load (i'm guessing vacuum leak?) Then this morning I got in it and soon as it started #3 cylinder had a miss and never went away (p0303) Plugs and wires are only a few months old and there is definitely spark at the coil when I pulled the wire off the coil. I also have a code p0171 but I think thats due to a slight leak at the manifold and y pipe. I don't know if this is all related but any help would be greatly appreciated because I am stumped. Thank you
