Boscoe99: The Link & Sync was performed by Hydro Tech, last year... The idle is rough, just doesn't sound like the old girl I use to know.. When i give it gas, it cuts out a little but seems like once it burns off the plugs she gets up and moves good. I had a tournament over the weekend in 27°...
boscoe99: I'm not sure what the pressure is while at idle but I will check over the weekend. I understand that VST will loose some pressure but didn't think i should loose that much. Hydro tech marine did a link & sync about a year ago.... This thing just acts like it's not getting enough fuel...
Qbhoy, I would think that if some injectors was open that I would notice it in the plugs but I could be wrong. I did open the VST and it was very clean. I take great measures to not run ethanol in the boat.I am actually taking the pressure ready straight form the VST. I will check the O2 sensor...
I have a 2002 Yamaha 200 HPDI (VZ200TLRA) and I’m having problems with fouling plugs and rough idle while idling. Once I can get it on plane it runs good. I have had it to two different dealers but they couldn’t figure it out so I started doing my own research and ran pressure test on the VST...
