MaxWedge I need your help!!!, (and anyone else for that matter)
I have the same exact problem as entry number 242, "96 88ls 3.8 non supercharged stalls out" post a few years back. Unfortunately, there seemed to be no resolution to the problem on that post.
My 94 Olds 88 started stalling out only when one went around right hand bends. Almost always did it when fuel was below 1/4 tank. Just shuts off like you turned off the key, almost as though centrifigal force causes the car to stall. Kick car into neutral, wrestle with the steering to keep from hitting a telephone pole, hit the key and it starts right back up. Occasionally shuts off when lifting throttle at very light throttle when approaching a stop light. No codes from OBD, and Fuel pressure is ok but replaced fuel pump and fuel filter anyway. Tried the Crank position sensor and the cam postition sensor as it seems that is a common cause of 3800's shutting off. No help.
Teenage kid threw a rod in the motor, so after a few expletives and him denying that he was flogging the car, I put a new motor in it. You can probably guess what comes next. The car still stalls!! The only parts used from the previous motor was the MAF and the ignition/coil pack, so I replaced them from a bad tranny car that I knew ran ok with no improvement. Mechanic thought it possible that he got a bad fuel pump, so he put another in it and checked the wiring and looked in the fuel tank for something that might be rolling around in it or broken baffles. No trouble found.
Now it is stalling going down hills also, but car stays running with no power or ability to increase RPM's. Stop along side of the road, car is running, pull back onto the road and all is well for a while. Whoa to you if you come to a stop sign that is on a downhill grade. Shuts off and won't restart unless you can coast to a flat spot. Car rpm's also surge up and down slightly as it idles.
Any ideas, anyone????
It has a different motor now in the car, so everything is changed as far as sensors, etc... but it has the same problem. Vacaum hose?? Fuel pump relay?? Why would centrifigal force cause it to stall?? Bang head here ->
Thanks in advance.
