More than part throttle or WOT is fine. Cant hear a "miss" to speak of...

Had some real old gas in it which is about burned out, new plugs and fuel filter yesterday. Topped it off with fresh premium and drove it about 90 miles, no change

RC205, 2-3 yrs old.

Anyone experience this and what was your fix? Thing ran perfect when I parked it last year.

If I have to pull the plenum to fix it I can kiss Vegas goodbye this year but I gotta get this done. .
