If your goal is dependibility, do the vaccum lines. Other stuff will go bad, but vaccum lines are 'Enemy #1'

Yea I had this same issue. New TPS solved it.

CyCloNe!

I just installed a new tps and still getting same result.... it will idle sometimes for ever and other times just for 2-3min and shut off.... it says around 1000rpm and then it surges in idle from 1000rpm to 800 then to 1000rpm then dies... dunno

ive even tried the DME jumper and it still had the same results

Have you physically checked the Ref sensor lead from where it connects to the DME to the plug, into the ref sensor? I'll bet you have a frayed wire there somewhere within the lead. I would start at the boots, where they connect to one another.

Maybe:
Bad DME.
Rusted grounds.
Bad Ref sensor.
DME Temp Sensor.
Also disconnect the O2 sensor.

Ok guys I replaced the tps, isv and deleted the venturi and replaced my ignition coil which i found out had a damaged terminal. Knowing my luck I probably fixed a car by a 340 dollar solution that was only a 40 dollarr one lol.... anyway car seems to run normal.... idles at the 900 mark hasn't cut off or died yet at all... I'm still eriee of driving it much but I guess it will get better in time.

lol. The ole' replace everything tick!

CyCloNe!

lol yep, when in doubt replace everything you suspect... i look at it as preventative maintenance that way its taken care of probably for another 50k plus lol

Did you ever fix the problem? How was the boost when all this was going on? Was it just at idle it ran rough?
