robertlane,
This dead spot is upon accelration while the vehicle is moving. It happened to me as I deaccelerrated on a on freeway on-ramp, turning to the right then upon acceleration to get onto the freeway, there was nothing when the gas pedal was depressed, then appx. 2 seconds later, the engine / RPM's retruned. There is no increase in RPM's during this flat/dead spot. Could this be a TPS?
