Technical Head Gasket?

[Zwyczajny]

Hello everyone. I'm probably most unlucky Fiat Panda owner .
Because i've got some ignition problems last time i was replace spark plugs and high voltage cables with unsuccesfull solution.

Today after few kilometers on higway my panda start to shake and lost power with check engine.
I stopped at the nearest foot and read the errors.
If coil replacement doesnt help it mean my head gasket was damaged? First spark plug was totally black and last less black, but still when i'm replacing them.

probably not the head gasket

But if i swap coils and problem still will be on 1 and 4 cylinder not 2,3 what it can be?

wiring

do a compression test by all means.

which engine

 

[Zwyczajny]

1.1 8V Fire with square oil filler cap.
Wiring seems to be okay. Last time i check all connections when looking for problem with ground.

sounds like the common 1.1 error. caused by the ECU pug

normally worse over rough ground

some have had success with a cable tie

The spark plugs for cylinder 1-4 and 2-3 are connected directly (two at a time) by means of high tension leads to the terminals of the coil secondary winding and their connection is in series because the cylinder head joins them.This solution is also known as the 'lost spark' becuse the energy accumulated by the coil is almost exclusively discharged at the electrodes for the spark plug of the cylinder under compression allowing the ignition of the mixture.The other spark is obviously not used, as no mixture is found in the cylinder to ignite, only exhaust gas.

I see you already have had electrical problems

Good morning! I've been having big electrical problems with my car lately, all kinds of things are happening. the last problem I noticed and probably the most serious one is what is in the film. While adding gas, the fuel level drops and the handbrake indicator light flashes. Which plug to see...

I have already tried everything with the plug of the IAW-4AF computer. I cleaned the contacts chemically and mechanically and with ties around. I was not able to remove the pins of any wire because I would bend them a bit, but I did not find a way to do it. Then I could definitely rule out the lack of connection. it is possible to disconnect the cables from the computer plugs?

next time its misfiring test the HT

don't do this if you have a pacemaker

Take you pick from this lot. https://www.ebay.co.uk/sch/i.html?_...m570.l1313&_nkw=HT+lead+spark+tester&_sacat=0

But its just as easy to use an IR thermometer on the exhaust stubs adjacent to the cylinder head (cold engine of course). All four should warm up equally. The one or two that stay cool for longer are not firing properly. On cold start, the cause is most likely ignition related.
