Just an FYI, I had been experiencing a loss of power over 4k RPM and thought that it was due to my pre-cats being bad(P0420). Had the manifolds replaced (under warranty
) and still had no pwer in the upper RPMs. It felt like the secondaries were not opening. So, I took the plastic cover off the engine and followed the IMRC cable, thinking that maybe it became disconnected. Well damned if I didn't see the problem right away. The linkage between the two banks of butterflies had come undone, on the bank 2 side (closest to the radiator). It looked like some sort of retainer was missing in the lever. Went down to local dealer and bought the retainer (part #F5RZ-9F955-AB) for 3.69 with tax. Put a loop of duct tape on the end of a flat head screwdriver, stuck the retainer to it and snapped it right into the lever. Snapped the linkage in and went for a drive. SO much better! now it's pulling like it's supposed to above 4k RPM!
I just did a search using that part number, found six posts. Sorry, searched before buying the part but didn't know what to call it or the PN!
Oh well, Not like it's a subject that's been beat to death! Makes me wonder how many people paid a dealer hundreds of $$ to fix this!
