I need some assistance in troubleshooting why my engine cuts off when coming to a stop. First let me give you some background and details to help you. I just finished an all-motor performance rebuild on my 2000 Civic Si and I now have approx 1100 miles on the rebuilt engine. The changes are listed below. Some things that I have done to try to fix the problem are 1. Advanced the timing to 18 degrees BTDC 2. Adjusted and set idle to Honda’s specs. 3. Using NGK plugs PFR6G-13 and verified gap to be within specs. The engine dies only when I come to a stop, and occurs 80% of the time. I can be going down the road (no stopping) and disengage the clutch making the engine fall to idle. When I do this the engine stays running every time. Any one have any ideas. Your help is greatly appreciated.

Thank you,
Michael

Its problay cause your bottomend is too damn light. The B16 crank is already tiny compared to a GSR and the Grand daddy of the all the ITR. If you sat all 3 cranks next to each other you notice a HUGE difference in size and weight.
