I have a 94 explorer 2 dr great condition. Alot of people say explorers have great power well my does not. when Im going about 35 mph on a street and a floor it , it will only go to 3000 rpm thats the max. What might be wrong . I have all the up grades listed below.
Hey Nick, I would try the following:
reset the computer, clean the MAS, clean/re-oil your K&N filter, maybe even change/flush your tranny fluid. Hope this helps man!
The problem can be isolate to two area:
1. Throttle Body - you can take off your intake hose and inspect the TB to make sure its opening and closing properly. In addition, pull on the throttle linkage to see how far the TB opens up. If its not opening up enough, you may need to adjust the TB to allow more air to flow into the engine. This will allow you to hit Higher RPM bands.
2. Transmission - it can be any number of things. If your fluid has not been changed yet.... BINGO! Have your transmission fluid changed, in addition to the filter. This may be the culprit, if not, there maybe more serious problems.
Other than that, you should have not any problems revving your engine past 3,000 RPMS (all explorers are capable of revving higher than that). If you said 4,500, then that would be a different story.
Looking at the TB, it seems to open enough. Should the flap open until it is fully flipped on it's side?
Can I adjust the gas pedal? I would like it to be less on-the floor and a little "higher". I think something is wrong if everyone else says they can easily pass 3000 rpm (such as between 1st and 2nd gear) and my Explorer never does this.
Ya for a while my thick floor mat was behind the peddle. I found out you have to use the tip of you toe to give it full throttle. It also depends on what speed your at for the truck to shift & jump higher on the RPM's
Your accelerator cable is stretched out. Mine had the same problem. I could push my pedal quite a ways before it would engage the butterfly valve on the throttle body. I put a wire tie on the cable just in front of the cable stop where it mounts to the pedal. essentially this lengthens the cable stop, and removes the play from your pedal. It gave me about another thousand rpms. Mine still has a little play, but the pedal isnt nearly as sloppy, its something to investigate anyway.
