Hello. My truck is having this problem of stalling while driving or idle. Not when Im slowing down or anything but I'll be driving doing 55mph and then it will just die. I haven't had the PCM checked yet. I noticed the TPS was "loose or broke" so I messed with that. Took it off, cleaned it, then put it back on. I drove around for a bit and it didn't stall. It seemed to have worked but it was still loose/broke. So I bought a new one and put it on. Now with the new TPS its doing the same thing. Maybe I didnt install it right? I don't have a voltage reader but when I let it sit for about 30 minutes the truck will start right up but then stall after about 5-10min of running. Please help

Have you checked fuel pump pressure? Also, have you scanned the computer for codes?

I have checked the fuel pump pressure and it seems to be ok. I did finally get to a auto store and get the pcm scanned. It comes up with TPS and ECTS errors. I have replaced the TPS but it still shows the error code for the TPS. Even after clearing the codes it still comes back. As for the ECTS, I haven't been able to replace it yet. Its a rather cheap piece but a pain to get to. I do not have the tools to get it out atm. It also looks like I'll need to remove the A/C pump just to get to it again lacking the tools. I said I wanted a nice tool kit for christmas lol. As for now I have disconnected the ECTS and now the tuck hasnt stalled in a couple days. I still see the engine temps and they seem to read fine staying under 200 degrees. I am curious as to how bad it may be to run w/o the ECTS? I need to drive about 1000 miles this coming weekend. Im a bit worried about it, but its a must.
Thank you very much for replying to my question. Now my question is what risk do I face driving 1000 miles w/o the ECTS connected? How important is that sensor? The truck does seem to wana start rather rough but quickly smooths out and runs fine w/o stalling at all.
Thanks, Dave
