Message	Overall the car is running great. New custom top feeds and the Selin Dual MAF. Just this week I noticed a flat spot from 2400 to 2600 RPM. I hooked up the wide band and AFR looks fine up to 2400 then goes lean to as high as 20:1 till I just pass 2500 then all is well again. Happens in any gear. I can hold the pedal at around 2450 and the reading holds steady lean from 16.5 to 18. I haven't really started diagnostics yet but I am having trouble thinking of what could cause it at just that small range. Fuel maps look OK for that range too. Ideas? Thanks! KKROFFT Now occurs everywhere, simultaneously. But it doesn't have to be experienced the moment it happens.   Every now that ever was is still exactly when it was, when it was now.   Then, in terms of perception, is nothing more than all the nows that are no longer now.   Thus, the difference between now and then is when.    --The Waystoppers Users' Manual
