- '93 Explorer
Originally I thought this was temperature related. I have changed my mind.
93 ford explorer, idles fine, accelerates fine as long as it is in park and not moving. It ran 45 minutes this morning with no misses or acceleration trouble while I ran tests. Took it out on the road, gunned it, 0-40 quickly, then went into what I call " limp home mode". At this point (after drive) it doesn't even idle well in park, and when revving engine in park it stumbles around 2500 rpm, sounds like it is gasping for air, almost like a stuck choke. Shut it off, start it immediately back up and it is fine. Take on road, 0-40 then stumble, limp home, same cycle. Runs great as long as I don't drive it over 35-40.
It is throwing no codes.
NEW....
MAF
air filter
thermostat
coil
plugs
wires
Compression, vacuum, and fuel pressure are fine. Cat is not clogged.
Any help would be greatly appreciated.
