Hey, i have a 2005 wrx sti with 155k on the car but only 13k on the motor. Its the stock block with manley forged pistons rods and crank, i have a cold air intake turbo inlet and full exhaust on the car. So the problem i have been having is the car has been driving rough and randomly revving itself to around 2k rpm when it does this the cruise control light comes on flashing. While driving the car also accelerates by itself like i will be driving and let off the gas and the car will still accelerate for a second before it stops. I have been very confused about this issue any help would be greatly appreciated.
