adjust your TPS (another free "throttle response" mod)
TPS- Throttle Position Sensor
The TPS senses throttle movement and position, then transmits a voltage signal to the PCM. This signal enables the PCM to determine when the throttle is closed, in a cruise position, or wide open.
after doing some searching, i saw about 1000 replys stating that the TPS sensor on our explorers is non-adjustable. well, there is a way to make it adjustable just like the mustang guys have been doing for years. this mod will work on any Ford engine with a TPS sensor, V6 or V8.
Benefits-
better throttle response, low/midrange power, increased fuel mileage, smoother idle. it also may solve alot of elusive issues like rough idle, poor mileage, surging idle, etc.
what you will need
screwdriver
a few small sockets
30-60 minutes of time
drill with a small bit or a dremel tool
multimeter (something to read DC current)
you can get a cheap multimeter (even digital) at places like Radio Shack or Autozone for around 10-15 bucks.
basic idea
you can adjust the TPS to the ideal setting buy slightly rotating it either clockwise or counterclockwise. the sensor itself is held on by 2 bolts. you must "slot" the bolt holes in the sensor so that it can be rotated. what you should shoot for is a reading of .95-.97 volts. .96v is ideal, and thats what ive got mine set on right now.
were is it located on the engine?
the TPS sensor is right on top of the throttle body. you will need to remove a few covers/brackets to get to it. it will have a small cover over it, and will have 3 wires. the small cover snaps off. here is were it is located on the 5 liter-
