Auto accelerate
Hi i have a chevy optra 2004 1.8 since last 1 month
my car auto accelerate when i stop on traffic light
then break becomes very hard which does not
allow to stop the car easily and then even im
holding up a break its will keep accelerating...it
seems like it want to run away and some times car
rpm goes down then engine will turn off...i change
buster pipe to new one but still problem is there...is
this because of bad throttle body????
