Attained a 1991 Alfa Romeo 164 V6 QV manual ths week, i have had heaps of autos but this is my first manual, very fast 164!!!
She has been idling on 2000rpm on startup (sometimes 2500) for around 30 second to a minute then she would drop down to normal, now startup, warm and hot she is always idling on 2000rpm or more and will not drop no matter what!
Is this a common 164 manual fault??? Never had a problem with the autos always baby bottom smooth idle.
So far i have replaced the IDLE ACTUATOR, AIR FILTER and FUEL PRESSURE REGULATOR and these items have made no difference whatsoever!
Could the MOTRONIC ECU have a idle fault???
Any ideas Steve or any 164 manual owner to save me diagnosis time???
Thankyou VeeSix
