[QUOTE="96dreamer, post: 16664895, member: 52560"] Well i was finally able to drive the car and the lean spot appeared to be gone and the car drove and idled much smoother so I thought the problem was cured. However after reviewing the logs the passenger side is still experiencing the same lean spot, although significantly improved, and the AFR fluctuates quite a bit more than the driver side that has the damper. My theory is the distance from the damper to the passenger rail is not allowing it to sufficiently dampen the pulses in that bank. For reference this is what the fuel system looks like now.

I am sure this is the most effective but I am not sure it is needed and it is the most costly option.
