- 2004 explorer xlt
I have a 2004 xlt with a 4.0 sohc . It had the timing chain rattle for some time.My wife was leaving the other day and after about 5 minutes on the road lost power. the broken plastic chunks told me what was wrong. Soooooo I pulled the motor and replaced the timing chains and water pump and all the gaskets ...basically a complete rebuild of the top end.Now its back together so fire it up and it runs like a top! Step on the gas and it falls on its face it wont go over 2000rppm. Ive replaced the mass airflow , throttle position, and rear diff speed sensor to no avail .Any one got any idea? engine off butterfly opens and closes normally but running it will not open and engine floods
