Similarly with the EHA current, on warmup, steady 8mA, once warmed up, it sky rockets to 16mA and won't come down at all.
Now from my previous reaserch this tells me that the mixture is lean, and the computer tries to compensate by enrichment.
I tried to lean out the mixture, I adjusted and adjusted but I get to the point when the engine bearly runs and neither the lambda nor the EHA current change one bit.
I'm scratching my head on this one. If you think it's lean already, then why are you trying to lean it out more?
