About 45min ago I was on a long stretch of highway with no cars in sight so I decided to have some fun and do a little WOT highway pull. I downshifted into 4th gear and floored it. Then all of the sudden my car jolted pretty hard and lost all its power. Then my CEL came on and the cruise control light is flashing. I babied it the rest of the way home. My mods are in my sig and my WRX as about 8,000 miles on it. I'd like to avoid the dealership as much as possible because I don't have the time or place to return my car back to stock and have it checked out. Some please help!!
