Re: EF rich Idle mixture
it could be a number of things, map sensor,coolant sensor, fuel regulatorand also the fuel pump(relief valve faulty=high fuel delivery)
I've been have some problems with something similar, I have an EB11
its been flooding but it started being a problem at idle and got worse.
I'm about to change the fuel pump(which is new) as the diagnostic computer I have (snapon scanner, father owns mechnic shop) gives no problems.
oh almost forgot the power steering sensor also controls idle speed, if its faulty it will cause bad idle
I'll Keep you posted on the fuel pump idea as i'm puting in a new one tommorow.
