Further installments are needed to be written here.
Due to the ongoing idle problem , I have persevered with this , I have done absolutely everything for the idle symptoms on this car and one thing has led to an other, I have downloaded Fiatecuscan and paid for the full version.
I reset the parameters as I have done with alfadiag before and noticed a different reset procedure, any way as I reset the key on and off the usual occurred albeit with a warmed up engine it would fire but not idle so i noticed by backing off the throttle to get it to run the engine ran so smoothly compared to before right down to idle rpm, before it was very lumpy and up and down especially if you tried to hold it at 1500 rpm. This time it was smooth so i took to turning the stop screw on the throttle arm and when finall at a happier idle it hummed at 850!!!!!!!!!!!
I am not sure if this is luck or even by adjustments needed I t idles well. Took the car out for a good run and seemed fine , went into a shop and came back to start it floundered like the compression nwas too high , so I gave it some trottle and no result, so I left the throttle alone and it was fine.
The next stop was the same but found that when I backed off the throttle while decelerating the revs took a second or two to come back to idle ,noticing the car would run on a bit .
Back home I took the stop scew back a bit and everything seems to be better.
The only other thing I noticed is that when ever the fan comes on at idle,the revs quite rightly so increases , this is not unusual but a tad higher.
I can only say that at last I have a totally restful idle and getting there.
Without giving away what I think next , has anyone have any thoughts to curing the temporay slow down in throttle relax to idle.
