So lately since ive been driving my car its lost ALOT of power since ive been keeping the revs under 25 and rarely smashing. Last time i raced i got no chirps and no wheelspin at the start i felt like a prius. i won and everything but i lose Alot of power in 3rd and 4th where if i was in those gears before and i was ahead id keep the lead and they wouldnt gain. Any ideas why its like this? Its also shutting off randomly while im driving just for a sec but it always bothers me for a few min hoping it doesnt happen while im taking a corner and i hit something again
