I own a 1993 oldsmobile cruiser"S" Wagaon. The problem I have occurs when the outside temp is 80 deg or higher and I have been driving for 30-40 minutes. The engine appears to have a miss and sputters and then stalls when I slow down. The engine will start immediately after each time this occurs. I can rev the engine to 3000 plus RPM without any hesitation. However the engine will stall when placed in gear. If I allow the car to cool for 20-30 minutes I can drive the car for another 10-20 miles before it happens again. I have changed the; fuel filter, fuel back pressure regulator, ECM, plugs, wires, a "suspect" bad coil, air filter, various vacuum hoses, engine temp sensor cleaned the MAF sensor. I am leaning towards a transmission problem possible a speed sensor.
