So back in April I took my car in for Oil Change and routine servicing (7500 miles I think) and the mechanic told me that he could tell that there was something slightly out of whack regarding the engine's idle. He said he could notice just sitting in the driver's seat and listening to it idle and also when he put his hand over exhaust in the back. He said it sounded like a fuel injector problem and he told me to put some STP in it (the Red container which was the regular fuel additive and the Black Container which is supposed to be used every oil change) and just go drive on the interstate for a while. (I drove from Seattle to Vegas to San Fran to Eugene, Oregon the next week)
I would like to know if I've corrected this problem. Is it possible for my untrained ear (or to feel the exhaust like he did) to decide if this problem has gone away?
A little background:
-2006 WRX Wagon
-It didn't get driven a whole lot the first year I had it (only ~3000 miles) because I had to travel a lot, and it sat for almost a month undriven on two occasions
-Since then (April 2008) I've put about 10,000 miles (95% interstate) on it.
-Maybe every 2-3 fill ups I will put some of the STP red container in, and a container of the black STP every oil change.
-I've always put in 91 or higher (now that I live in Texas she gets sweet sweet 93)
-My MPGs seem fine, I get 24-27 on the interstate and ~18-20 in the city
Thanks in Advance
