Hello guys! Permanent misfires or sporadic misfires, whatever it is, it is essential to always follow the diagnostic method and assume nothing! Always see point by point what is good and what may be missing. I already have several situations of crank no start, difficult starting, lack of power and others on the channel, it is here a little further down in the description in the links to that effect.

It takes a great mechanic to admit nobody is perfect and to put it on camera!

You are a good man, Bruno. Only who keeps his hands in the pockets does not do mistakes. *Twince two different mechanical forget to tight my wheels. Last time a fault sealing on my JTD cost a massive oil leak. The mechanic pay a night in B&B for this issue.

I always try to do things like this. A car that I delivered two days ago, customer said the side blinker now comes off. Ok, I did not messed with that but I did order a detailed wash and clean, maybe it did affect the side blinker. So I will send a new one to the customer.

I would also recommend you to check ignition coils for cracks. Normally there is tiny crack on each coil on the bottom side. Though it is tiny, its enough to cause misfires.. look carefully, I have not seen a single 20+ year old ignition coil without cracks on this engines.

@alfaromeonoproblem 13 күн бұрын

Hello. I'm aware of that, these ones are very good, but I had a GTA here with 4 bad ones, 2 of them seriously cracked. I had another 3 liter 166 with all 6 checked... But this ones are good, odd enough

It happens to all of us. I bought two sets of spark plugs, both turned out to be Chinese NGK and the spark plug leads had the wrong resistance, finally got the correct parts and my Alfa now drives well. You should also check for vacuum leaks, although I had new gaskets on the exhaust and intake it still leaked. RTV red on the exhaust side, on the intake removed all four "new" carburettor mounts, removed the studs and belt sanded all I sides, not one was flat. Getting sick and tired of buying new faulty parts.

That is why I always sort by price, highest first. But not even that is a guarantee sometimes.

A misfire from spark plug or coil most of the time throws pulse check light(active). O2 sensor if they are defectife throws check(static). But bruno is brave enough to solve it with out any obd.

The dancing rpm needle was a good indicator of a crank sensor issue. Also it should have been visible on live data.

@alfaromeonoproblem 13 күн бұрын

Hello. The symptoms before and after on the middle and live data were exactly the same. The rpm needle on these gets a bit loose and imprecise with time. On live data it's not fast enough to read bad.

@@alfaromeonoproblem Ok. What i hate about these engines is that it has inly one cam sensor. Good luck finding a bad timing. The only way is to get it apart and put on the camlocks.

Have you checked crank sensor cable? Sometimes it melts to the engine and makes problem on temperature change.
