well, to start things off, about a month ago, I was pulling on to the highway and when I put my car into third, the engine suddenly died.
When I had a mechanic work on the car, it was discovered that my turbo wastegate had jammed. I'm not too knowledgeable about turbos, but would that cause the engine to misfire? What could cause it to jam? Is there something to prevent that from happening? The mechanic told me to get a turbo timer, that heat from the turbo caused it, but with a water cooled turbo, that sounds like BS. I think a turbo timer would be a waste of money.
Also, after getting my car back, I can hear air when I step on the gas, would a K&N drop in do that? Also, after spooling the turbo and letting back on the gas, I can hear pressure being released. I have a 2005 WRX, completely stock, except for the K&N drop-in filter.
