Sitting at 75,000km on my 2015 STI, stock, and starting to get some low rpm issues.
For the last couple months, it has been idling rough ( worse when cold/just after start up) and has gotten to the point it will stall when I clutch in at a red light. I have to keep my foot on the throttle to ensure RPMs stay above 1000, any time they drop under I get a really rough idle and a chance it will stall.
I assume it is related, but I have been getting Cylinder 1 misfires once every couple of weeks, generally in the same conditions cool/just started engine at low rpms.
Any suggestions? I am going to start the mind numbing process of contacting the dealer, but I can guarantee without a CEL they will not do a thing.
