# 1B117277. Engine starts and idles fine. Slow out of the hole but gets up to 5200-5400 RPM quickly after trimming up. After running for a few seconds, you can feel the engine stutter or lurch and RPM goes down to 4700-4950. I’ve had this issue a little while but it was worse yesterday. Any thoughts, ideas, or questions? I can give more details after I see what questions you have. Appreciate it.
