I have a 92 lumina apv with the 3.8L V6 with 137000miles on it and while it's my everyday vehicle right now it will turn into a project beginning next year. I want the grand national motor in it then, but for now it's driving me crazy. I drove the van on the interstate for 2000 miles without a single problem moving from the east coast to the mid west. but since I've had it here it caused me one problem after the next. First it would just die and not start back due to lack of spark, so I replaced the coil pack, ecu, maf, tps, and the wiring extension to the cam and crankshaft position sensor. That solved that problem. Now for the last 3 weeks it does fine all week long while I only drive it short distances but on Fridays when I have to make a 50 mile trip it gets worm shows me no oil pressure and stalls at the red lights unless i switch it into N and keep my foot on the gas, so I am think (hoping) that it is the Tcc solenoid on the transmission and not the whole stall torque converter, but I don't know where it is at.ANY Help would be greatly appreciated. I plan on swapping out the timing belt water pump cam sensor and crank sensor next weekend and would like to take care of the tcc solenoid then too. Thank you very much.
