Hello guys,
I have a 1.2 8v Doblo that is a bit rough at idle and it is difficult to start (it always start, but it seem to be doing too many revolutions before actually start: as a reference, I can count 1001,1002,1003).
Air filter, spark plugs, HT leads and battery changed; no improvement.
In the next days, I will change the muffler and an exhaust pipe.
I did a quick copression test, engine warm, only dry test.
cyl 1: 11 bar
cyl 2: 10 bar
cyl 3; 9.9 bar
cyl 4: 9.9 bar
seems pretty consistent, perhaps a bit lower than I expected ....
the insulation of the HT lead on cyl 1 was a bit damaged...
I've checked the ECU using MES, but at a first glance nothing seems out of the ordinary. I've tried the self adjusting procedure (three times a 4500 rpm for 3 seconds) and nothing change.
Tomorrow all try the auto learning procedure for the phonic wheel.
At high revs, the engine seems ok, without loss of power.
Any suggestion of what to check first?
Replace the coil where the slightly bad ht leads was attached?
Check for poor timing belt fitting?
Thanks
