I am having an operating anomaly with my FI.

I won't go into too much detail here but basically it appears that the fuel delivery to one rotor goes way lean anytime that a steady state throttle position is set.

I know this because I have dual AFR gages. One stays nice and steady where I want it the other goes so lean that it stops registering. Obviously this is a problem on the back straight at Road Atlanta!

I have done expensive diagnostics/replcements to no avail.

Due to the nature and amount of the details it would be easier to talk with someone off line via phone.

Guess I'm looking for a crash course in Mazda FI tech. Someone out here must know the fundamentals of how the Mazda system works and could suggest a diagnostic tree to chase the problem.

If anyone is interested in helping me out leave a post and phone number/time to call and I'll give you a jingle.

I dreaded this day when the electronics went wonky but there must be a solution.

Thanks
