Imagine what WRX with exhaust sounds like when it idols...kind of choppy and "missy". Like I said, no CEL and definitely lack of power i.e. cant accelerate without giving the car a ton of gas in order to go past the dead spots.Really, I'd like to know what "sounds like a Subaru" means. Is the engine missing? Is it bogging, when you drop the gas pedal quickly? Does it idle rough? Each of these things has a different cause. How about you get a lot more specific about what you engine is doing???
