Hi All,
The car is a 2001 forester st/b sti with an ej205 looks to be similar to 1999 Impreza After replacing half the cars sensors it feels like it is still idling roughly. when hot if you pull the vacuum line from the blow off valve it will idle much more steadily and not as rich. Here's the logs for the running normally
Link for video of it running with vacuum lines and warmed up and link for video of warm but with one vacuum line unplugged when checked it was at 700+ revs So far i have checked: Coil pack, Spark plugs, MAF, o2 sensor, corrected throttle position sensor, Checked injectors, New fuel regulator and filter. I did notice that during first start when cold it will raise the revs only for a minute and then instantly go to 500-600. It also struggles to catch its self after revving to about 2-3k
Its come a long way but still not fixed and I've ran out of ideas tomorrow I will try clean the iac but I doubt it will help. The day before we adjusted the throttle position sensor unplugging it made the car idle perfectly if that is any help
Sorry for my formatting
