I have a 1995 ford f250 5.8 gas first thing in the morning I have to shoot ether to get it to start after that starts right up idles a little ruff under heavy acceleration it sputters backfires and wants...


Sounds like your fuel pump starting to die. It is not getting enough gas under heavy acceleration which is 100% fuel pump slowly dying. At start up it might not be building up enough fuel pressure to feed the system but the shot of ether and engine cranking helps pressure the system just enough for the fuel pump to trickle the gas and run the engine at low rpms.

Misses and sputters at certain throttle position


This sounds like the same problem I had with my 87 Jeep 2 door Cherokee Sport.
Thought I had to replace the Fuel pump yet when I went under and pulled it out of the side of the tank I found that one of it's vacuum or return line had fallen/poped off. After I pushed the rubber tube line back on it's metal tube and pushed and remounted the pump back in the tank. Started up and it never ran better at any speed. Yea!!!!!

What does the ect dash light mean


ECT stands for Electronically Controlled Transmission. When you push the button in, there should be a light on the dash that says "ECT POWER". This changes the normal shift times (based on engine vacuum, rpm, and throttle position to a later point. This means simply that the engine rpms will go higher before shifting to a higher gear when you're accelerating. It helps build speed more quickly but uses more gas to do so

My xj6 runs at high rpms and accelerates on its own


None of those possible problems have anything to do with idle speed. The first thing might be a very weak throttle return spring. The next would be a sticky throttle cable or foot feed pedal that isn't moving freely. Another possibility is a vacuum leak somewhere. Did changing the spark plug in #1 cylinder help the misfire? If not, you may have a partially plugged injector. Fixing the misfire will only increase idle speed some more. Look for an idle speed motor near the throttle body that is supposed to raise idle speed when the engine is cold and lower it back when the engine warms up. Check to see if it is holding the speed too high. If the throttle position sensor tells the computer where the idle speed motor is set, then it could have an effect on idle speed if the sensor is bad. The position sensor is just a fancy potentiometer. Hope some of this helps.
