1996 V/P 454ci with a DP-S1 with OEM fuel inject system. All injectors were tested about 1 year ago.
We had this long block put in by a friend a couple years ago and we average 25 hours a season here on Lake Erie. If I come off plane and don't feather down the throttle it tends to stall and there is even a bounce into low rpm even when I take it slow. Seems to idle just fine auto about 800 rpm around the marine but it will stall every now and then at dock when warm.
New filters this season and the issue is slightly worse this early summer.
Being F/I I assumed everything was mapped and not much control like an old carb engine. Thoughts on what I DIY like me can check before I make this an issue with a mechanic that won't have time to look at it anyways for 2 months in my area!
Thx.
