2001 XJ with the 4.0. I wrote about a week and a half ago about idle issues. The vehicle wanting to stall out on me at idle or switching to reverse. The check engine light is not on and it's not triggering any codes. I finally took it to the garage where they cleaned out the intake plenum and reset the parameters on the computer with their OBD II tool (I'm assuming.) Everything ran great but I was not optimistic that it was going to stay running fine. I was right. This morning it started up again after about a week of running fine. I know one of the sensors is not working right. Whichever one hasn't failed to the point that it kicks the check engine light on but is enough to throw the computer off a bit.
My two questions are: I suspect the TPS may be the problem but at $66 I don't want to just buy one for trial and error. What's the correct procedure for testing the TPS?
My other question is Sears has a computer for reading the codes for around $200 that I would like to get that has the ability to reset the MIL. What is the "MIL" and is that the same as the garage did when they reset the parameters on the computer? The garage had said that the vehicle would run different than we are used to because of that with possible different shift points. Thanks and sorry for the length.
