While driving 91 olds cutlass supreme engine revs high but speed does not match, transmission fluid levels are normal


It's possible that the transmission modulator hose came off the valve or has a hole in it. Check the pass side of the trans for a hose hanging or other problems. If not there, check where it hooks to a vacuum source at the engine.

Need firing order for 89 olds cutlass supreme 3.1


To be 100% sure it is 1-2-3-4-5-6. Your number one Cylinder is located on the backside of the engine (closest to the windshield) on the Passenger (aka right) side of the engine. Number two is located on the front of the enging (closest to the bumper)farthest right (passenger side). So the cylinder numbers on the back of the engine are 1-3-5 and the cylinders on the front of the vehicle are 2-4-6.

I have a 96 Olds Cutlass Supreme that intermittently won't start


If the lights on the dash all come on but the engine wont turn over it could be a problem with the VAT security system. Your key has a little chip on it between the teeth and the handle. This is a common problem with GMs', often just replacing the key is necessary but sometimes the VAT module needs to be replaced.
