- 2000 Ford Explorer XLS
Hey there,
So I can't seem to figure out the issues with my truck. I recently bought a 2000 Ford Explorer XLS with the 4.0 OHV and Auto 5spd with OD. Since owning, I've enjoyed the truck, and it is a very capable machine... When it is running right... The vehicle has a very serious misfire, throwing a code for Cyl 4 when I had first got it, now throwing for Cyl 3, no longer 4. It is also throwing a Sys Too Lean Bank 1&2. The misfire is intermittent, and seems to be getting worse when it does occur. Before it would only occur under heavy load/throttle. However, now, it seemingly occurs no matter what I do, and will eventually straighten itself up after around 10-15m of driving. It also seems to somehow be connected to how much fuel is in the tank. As at 3/4's to 1/4's, the miss is mostly nonexistent. However, that may be coincidence, as it will occasionally occur between those marks. It also seems to have some issue starting now.
So far I have figured out what it is not, by throwing money into it blindly. I have replaced:
Finally, my transmission recently started to Over-Rev when shifting from I believe 2 to 3. Possibly 1 to 2. Last check of the trans fluid showed it was alright. Seemingly only when cold.
Any help will be greatly appreciated.
Thanks,
Andy
