Sorry if this get a little long. I would just like to explain what is happening and try to find a real solution.
I have an 88 XJ 4.0 with AW4 and 231 tcase. I have only owned this jeep for 3 months. When I fist bought it I was actually impressed with its power (acceleration). If you pressed the gas on the XJ it would really take off. Well times have changed. It feels VERY sluggish now. It even stubbles if you accelerate to quickly.
I replaced the spark plugs, wires, cap, rotor, fuel filter and air filter. None of this has helped the problem.
I now have a new symptom also. My part time light on the dash comes off and on. It only comes on when I am coasting. Like when I am coming down a steep hill and let my foot completely off the accelerator. As soon as I begin to press the accelerator again the light immediatly goes off. The only exception is that if I am coasting to a stop and I press the brake pedal. The part time light will stay on until I release the brake and press the gas.
Today I spent a good 2 hours looking for a vacuum leak. All I could find is a Blue vacuum hose that comes from the harness that is connected to the hard lines from the transfercase, Disconnected. It is with a group of vacuum lines that run against the passenger side fire wall, under all the a/c lines, along the fender and down to the resovior bottle behind the bumper.
Is this BLUE vacuum line supposed to be connected?
If so where? I could not find any place to connect it.
I really hope someone our there can desifer all this rambleing and help me find a solution to my problem. I really need to bring the power level back up to there it was!
Thanks in advance for any help!!!
