o/d light flashing
I have a 2003 F150 Super Crew, 5.4L engine. Lately the O/D light is flashind when starting the engine, and I have notice the engine on idle accelerates while the engine temperature is not cold, as soon as the engine goes to normal idle RPMs the O/D stops flashing. Has anyone had a similar problem?
thanks,
Antonio
p.s. I am taking tomorrow the truck to a mechanic to get the codes.

Clean your throttle body and MAF

After cleaning the thottle body and changing the IAC valve the O/D light has not come up, the engine is running smoothly and I also feel the gears entering more smoothly.
p.s, also the check engine light is not on right after changing the IAC valve.

Sorry to say nut problems returned after a day of driving. Engine RPM go up, and O/D light start flashing.
These are the error codes: P1702 TRANSMISSION RANGE SENSOR CIRCUIT INTERMITTENT.
Could this be the cause? a range sensor causing the engine RPM to go up?
