Hi everyone, I am a new registered user of this forum, but it has helped me find answers on several occasions. Unfortunately, this time I am stumped. I have a 1997 F150 4.2L. Most of the time, it runs fine. Recently, I have been having problems while driving. It seems as if the engine will not take the fuel. It does not stall, it just loses all power, and the RPM's drop. Electrically, no loss, and if I push in the clutch it idles fine. If I press the gas pedal, the engine bogs down and will not accelerate. I had it in the garage for well over a month, and they can not find this intermittant problem. No fault codes come up. They have replaced the fuel pump, mass airflow,egr,and tested most all sensors related. Fuel pressure stays stable when fault occurs this was verified with gauge. ????? Any ideas?
I ran for the last 2000 miles without a problem, and yesterday it started again.
Thanks for you input!
