Having some probs w/ my 95 montero ls - no mechanic can figure out the prob b/c it's intermittant, only happens about 1 time every 3-4 weeks. While driving truck will all of a sudden 'starve of fuel', i.e. begin to slow down b/c there's NO FUEL getting through. I lift up on my throttle and after 3-5 seconds, fuel will get through and truck will move, then, no fuel, then fuel, then no fuel, then fuel. Nothing else is affected by this, i.e. radio, lights, heat.

I get to my destination, turn off the engine and let it sit. Back in truck, will run perfectly for several weeks when it happens again during a drive.

It's never left me stranded (yet) and is driving perfectly otherwise. Had a friend hook me up to a codes machine, TPS came up. I replaced the TPS ($$$) and the next day, truck did it again. That was 2 weeks ago and since that day, it's driving fine. Does anyone have a similar problem or have any idea where I could start looking? No codes are coming up and I have decided to drive it until it does leave me on the side of the road - unless I can figure out what the prob might be.

(Am over 6 months pregnant and really don't want to be left on the side of the road if I can help it.)

It's been another 4 or so weeks it's been great and today it went back to the starving of fuel, then fuel, and then starving again. I went directly to a garage and they got code 14 saying it was the TPS again. I told him it showed that before and I JUST had a new TPS installed a little over a month ago. HE sd he kept erasing the code and doing it over again, kept getting that TPS code. He told me it probably was the computer b/c he checked the wires from the TPS and everything seemed to be good connections. HE also told me to go to the dealer - I hate to do that b/c they always seem to try to rip you off, especially since I'm a girl. But I guess I don't have a choice?

He also sd something about the closed throttle position sensor or switch that the computer is possibly not reading. ??????? Again a possible problem which you mentioned. Does that sound legit?

You sd a good mitsu mech can figure out the problem? I seem to be getting nickeled and dimed now and I'm tired of it.
