This may be the dumbest car-related question ever asked on the SDMB, but I know very little about cars. Please forgive me. :o
Anyway, can you improve your gas mileage by disconnecting a spark plug wire? Mrs. HeyHomie drives a 2001 Chevrolet Tracker SUV with a V6. It passes everything but the gas station. If we disconnect two of the spark plug wires, would we be effectively turning it into a four-cylinder? Or would we be turning into an SUV that doesn’t run until the wires are re-connected?
IF we can run the SUV on four cylinders, doubtless the horsepower would decrease, but would it increase our gas mileage? If so, by how much?
