:worship: First of all About 2 months ago I had some issues and ran a ODB1 scanner on the ECU and it turned up 2 codes. One was for the TPS, and one was for the MAP sensor and they both were supposedly running below minimum recommended voltage. I replaced both of them, disconnected the battery for 20 minutes and then reconnected the battery. It ran better for about a day or so and the check engine light started coming on after warm starting. I ignored this (thinking that I had incorrectly cleared the ECU) and after many headaches as of late I decided to figure out what the codes were. It was the TPS (again) running below minimum recomended voltage. The O2 sensor is fine. The problem im having, is that when I first drive the jeep up to operating temp and (for example) stop by the store, go inside for 15 minutes or so. I will come out 15 minutes later, I can start the jeep the check engine light comes on and it seems to idle fine but as soon as I try to drive away or put it into reverse it just stalls and dies. I usually have to wait 30 -60 minutes before starting and driving away again. Also, I started driving places and not shutting it off, but now it doesnt stay idleing for more than 7-8 minutes before choking and dying. If im really in a hurry I can seem to pop the clutch and it will run fine( the check engine light doesnt even come on???) Dont get it? Im not sure if my TPS is to blame, but id still like to find out why my TPS went bad after a day or so. By the way, I have a 1994 XJ 5-speed with the 4.0L with 216,000 miles completely stock. Thanks for any input.
