Air sensor Plate is spotless I cleaned it last week good catch. I had my lines purged 4 months ago when I put a new filter on. Also had the distributor cleaned out to. I think it is definately something electrical. Either the throttle switch, eha or idle potentimeter as the lamda control (x11) is very intermittant at idle. The car was running great until I cleaned the engine, I was pretty careful but a day and a half later this hesitation showed up on acceleration, it also starts hard have to give it some gas. It does improve when the car is overly rich, but when adjusted to spec it is pretty bad. Outside of the hesitation on acceleration the idle is okay not perfect but solid. Power once moving over 10 miles and hour is amazing and very clean all the way through the power curve.
