I searched for this but could not find anything. I recently noticed this (and I am not sure it the car did this all the time) when I come to a stop, put in the clutch the idle will sometimes drop just a wee little below 500 and then go to 500. Just curiouse if this is normal. The car is a 04 WRX wagon with a little over 13k on it. I recently changed the air filter (it is in right...PITA for me) and went to mobil synth. oil level is good. It runs great, just wondering if anyone experiences this also.
Also, what does everyone get as a reading on the stock boost gauge at idle? Going to replace that soon with an omori in PSI Dang thing reads off zero when off pfft
Thanks in advance and HAPPY NEW YEAR (and be carefull!)
