It also has a very high idle. It won't do it when i first start and drive but after awhile it heats up and decides to start accelerating even without my foot on the gas. I recently swapped the ignition coil and adjusted the TPS to 4.07 (the manual said .05 to .075 however it i couldn't match that reading.) Could this be the problem? Also cleaned my throttle body out with carb cleaner and recharged my air filter.
