OK so this all started on the Charity Ride last year. T4 dies repeatedly like it is getting no fuel. It would happen randomly about every 10 or so minutes. Most times I could turn the key off and back on and it would fire right up. Sometimes it would take a minute to crank and multiple key off wait a few then back on. Thank you PC925. Anyway Matt took off my fuel filter on the trail because it was like it was not getting fuel. Thanks Matt. OK 6 months plus later, machine starts running like shit, backfiring then dies. Can't get it to start and it fouls the plugs. Change plugs can barely get it to idle then dies with fouled plugs again. Neighbor comes over with netbook. Download the PCV program off my T2 PCV reflash my T4 PCV, fires right up and runs perfectly. Week later, same thing wont start or run, fouls plugs. Reflash, fixed. Got a new PCV ready to install. VFJ says I can warranty the one I have. Cool, thanks VFJ!! Anybody else had a PCV fail, what were your symptoms?
