Engine Performance problem
1994 Ford Ranger 4 cyl Two Wheel Drive Manual 193000 miles
I have a 1994 Ford Ranger 4 cyl 5 speed Vin 1FTCR10A0RUD50946 While driving the throttle seems to get stuck and stays at a high rev. We have noticed it seems to be more often in damp weather. Spraying some fluid seems to help for a short while when sprayed on linkage, but always returns. We replaced the air filter recently and noticed screw gone around housing and fixed it. Seemed to run better for a while and back to the same old thing. Had a lot of people say it was the idle control valve. Replaced it today and also took carb cleaner and cleaned inside the throttle. Again, it seemed better more responsive and better power. Later in the day, happened 3 times within a mile. Each time my son would stop and spray the linkage and no success. We are about to look into the MAF but most posts don't associate problems like this with it. The throtlle linkage has been considered but since it is all sealed and nothing really exposed to corrode, felt it probably was not it but have gone no farther. Another suggestion was the throttle position sensor but that was replaced about 6 months ago when we were having starting problems. Mechanics have looked at it and don't have anything to add. I'd sure appreciate some help! Thanks in advance, Chuck
have the same problem?
