Hey, I'm new here. My name is Alex, and I drive a 2008 WRX sedan. A couple days ago, I put on a turbo-back exhaust and everything went smoothly. But lately my car keeps throwing the CEL. I'll be accelerating and about 2nd or 3rd gear, my car will jerk forward and the CEL will come on (along with the traction control and cruise control). After letting it sit for a while, the light goes off, and the car is fine for a while more. Then it will do it again, same story. Any ideas? Thanks in advance!
