Intermittent Power Loss
2003 Explorer Sport, 4.0 L, 84K miles. Car just fell out of extended warranty and has been serviced exclusively by the dealer.
While driving, I experienced a sudden bog down and inability to travel faster than 20 – 25 MPH. The more pedal you give, the less power. In neutral, free revs will not go above 3000 RPM at full pedal and will rise and fall between 2000 – 3000 RPM. The next day all is normal again. This happened twice now and I’m not sure why. No CEL, no stored codes. Plenty of pressure (felt by hand only) out the tail pipe except when fluctuating during free revs. There doesn’t appear to be any vacuum leaks. Does anyone have any ideas what I can check to correct this? Could it be bad fuel or water in fuel? Thanks for the help.
