'93 Bronco throttle goes unresponsive until I pull over then works again.?
Ok... so Im driving along on the hwy with no CEL, engine looses power and throttle is completely unresponsive. After coasting to the side of the road as I stop and RPM is at idle (about 700-800) power restores itself... Effin weird! Almost like throttle wont work until automatic choke kicks in. I have about a 25 mile commute to work and it seems to happen about twice each way. This is very dangerous because its rush hour and 12 miles of construction with no shoulder.... Anyway PLEASE help me figure this out. No codes
Its a '93 Bronco 5.0 A/T, so far I have replaced:
Fuel Pressure Regulator, Throttle Position Sensor, Fuel Filter, O2 Sensor, Air Filter, Plugs, Wires, Dist. Cap & Rotor, PCV valve...
HWY driving, loss of all power/throttle, can be fixed by stopping and letting idle drop??? Im so lost and going broke trying to figure it out.
Thanks in advance.
I think you have a mass air flow valve in line with the air cleaner tube, unplug the electrical connector and blow it out with compressed air but be careful as the small pins inside the connectors are easily bent. Even dust in these connections can cause your problem. I really hope that helps you because i have went through the same thing.
