I have just leaned out my fuel map on my auto N/A-T J-spec.It has since developed a strange idle which is no idle at all.After the engine is warm it will idle between 900 and 200 rpm and then just die,as soon as the revs goes above 1000+ rpm it runs ok.I am running a MAP-ECU.Will i have to reset the TPS values?Is ignition retarding needed here?My AFR at idle before the problem started was 12.5 when warm.The car has been running rich for a few months,but all sensors, O2,Lambda and spark plugs where cleaned prior to mapping.
Any idea peeps??
