So while I had the airbox off to do the PAIR removal, I thought I’d go the extra mile and pull the injectors, due to the fact that my fuel system was so gacked up from being parked for 10 years by the PO. (BADLY rusted fuel tank)
Three injectors came out fine, but the rear injector on the front cylinder left some crumbly black debris on the throttle body when it came off.
Looking closely at the injector, what remained of the OEM bottom seal was destroyed, and it looks like someone put a generic O-ring on there which is smaller than the others, also, the remaining 3 appear to be square in profile and not round.
Boy am I glad I removed all of this stuff and checked!!!
Next stop: professional injector cleaning and new seals.
