My '94 Explorer has the exact same problem. I still haven't found the answer for it. The MAF is a great place to start. Don't bother adapting any of your existing torx fittings for it though. Just grab a punch and gently tap down the existing little annoying middle tit on the two MAF sensor screws. They will crumble like soft POS white metal that they are and you should be able to get a regular torx on it after that(at least that's what I did). I'm not guranteeing that this is going to fix your sluggish gas pedal(mine is still like that) but it may help. Try what the other posters have said first(because it is great information) and then post back with any other problems. I'm not a mechanic but I have first hand experience with the dreaded '94 Exlporer. Good luck. |

1994 Ford Explorer 4x4 Acceleration Hesitates from a stop
alright i'm going to attempt to clean it today.
found a TSB on this: http://v8sho.com/SHO/TSB982310MassAi...tamination.htm i'm going to clean it with either maf cleaner or electronic parts cleaner. in that tsb it says if i disconnect the maf connector and take it for a drive and if the problems go away it's contanimated. they say to replace it but i will just clean it. also "DO NOT DISCONNECT THE BATTERY. IT WILL ERASE KEEP ALIVE MEMORY AND RESET LONG TERM FUEL TRIM AND BARO TO THEIR STARTING/BASE VALUES." i've also heard by disconnecting the battery it is a good thing for the computer to reread the values. whats your take on this?

also, how long would it take to reread the fuel ratings and such? will
mileage suck for a while?

ok puled the MAF out (didn't pull it out of the tube it sits in) just
disconnected it from the filter and the pip and sprayed the filaments through the mesh shield and it seems to run awesome. Starts right off the line. next question, how do you adjust the gas pedal? it seems like i have to touch it a bit more than usual before the revs go up or the engine responds. This problem was there before, or is this normal on explorers? jsanders wrote: > also, how long would it take to reread the fuel ratings and such? will > mileage suck for a while? > Jimmy the Hand wrote: > > > > > > > > JohanB wrote: > > > > > > > > > Don't forget the fuel filter and check/clean the maf sensor > > > > > > > > > > > > > > > > > > > > > > > > > > > "jsanders" > wrote in message > > > > > > > > > ups.com... > > > > > > > > > > Here is the problem with a 94 ford explorer.

My '94 is prone to the quite common "sticky butterfly plate in the
throttle body problem". All you do is pull off the air hose from the front of the throttle body and spray the heck out of it with a throttle body safe cleaner. There's a coating on the inside of the throttle body that you dont want to disolve. I also lightly wipe with a paper towel too to get some of the goop off. Concentrate where the butterfly plate contacts the body housing. I have to repeat about every 6 months. dickm On 7 Aug 2006 14:03:34 -0700, "jsanders" > wrote: >ok puled the MAF out (didn't pull it out of the tube it sits in) just >disconnected it from the filter and the pip and sprayed the filaments >through the mesh shield and it seems to run awesome.

I've disconnected and reconnected my batter a few times. I've never noticed a large drop in fuel mileage or vehicle response. I've also heard about this before but don't want to say much more due to my lack of knowledge it. |

hmm, interesting. anyway, it seemed to be a bit more hesitant, like the
timing was off just after i cleaned the maf, but after i took it for a drive, it seemed to work itself out. anyway, hopefully the computer will learn everything the way it should be because its going on a 1200km trip today and tomorrow, and coming back in a couple of weeks. so 2400km.surely it will take some statistics, because before the tune up it only got about 300km (186 miles) on the tank. Thats like 9 miles per gallon.

Thanks a lot for your help guys! I heard before the tune up and the maf
was cleaned, it would get about 320km (198 miles) on 19 gallons of gas. (9 - 10 MPG) Now, the update is 370km (229 miles) on 1/2 tank of gas, which would be 9.5 gallons i suppose. (22 - 24 MPG) Thats highway mileage though, but thats awesome for an explorer! jsanders wrote: > hmm, interesting. anyway, it seemed to be a bit more hesitant, like the > timing was off just after i cleaned the maf, but after i took it for a > drive, it seemed to work itself out. anyway, hopefully the computer > will learn everything the way it should be because its going on a > 1200km trip today and tomorrow, and coming back in a couple of weeks. > so 2400km.surely it will take some statistics, because before the tune > up it only got about 300km (186 miles) on the tank.
