I have a 2006 mazda 6 V6 3.0L automatic and I just replaced my TB the other day with an optimized TB. I dont have a gasket from the engine to the TB so i didnt think it was a big deal and installed it anyway. I started the car up and let it run for a little bit. When i took it for a test drive i was surprised. The car drives by itself. i dont even have to touch the gas and the car goes. it shifts and keeps going to 20 mph like nothing. but the rpms are high about 1500 when im at idle. when i drive it revolutions sound high and they keep wanting to change. the car just wants to go and keep driving. i have to drive with my foot on the brake. i think that since i have no gasket the engine is recieving too much air. What could it be?
