After replacing the spark plug wire Then drove the truck for about 3 weeksThe check engine light came back on had to replace a spark plug wire again 2 weeks later Check engine light comes back on. There's a problem with the wire or the distributor

Can't reach three spark plugs.4,7,8.How can I replace those 3? Want to know how I get to them to replace.

Not sure why else to change we change the throttle body sensor and mass air flow sensor still no change

Giving gas in neutral appears to remedy issue. Very random and sporadic?

Says it's a cam sensor, but it's been replaced and still does it. Any ideas what it could be?

Engine try's to stall when I accelerate or going up hill

Check your fuses. I drove without heat for 4 years in the front. Went to replace the blend door actuator and the old one worked after we tore apart the dash. I had a blown fuse. Go through your owners manual because there are several fuses that tie into the heating system. I had already had the radiator replaced, the heater core flushed and had several certified mechanics look at it. Hope this helps someone

functions work but the lights do not stay on when turned on. Changed bulbs and checked fuses.
