The weather was good so I pulled the cables and plugs out of my little Opel's X14XE engine.
This is what the plugs look like. Right to left are cylinders 1 .. 4.
The one I pulled from Cylinder 4 looks quite a lot different from the other ones which I find a bit odd and I'd like to know why this is and/or what might be causing this...
I put in the new plugs, connected the new cables and fired it up. It ran OK and after having run stationary for a while I took it for a quick spin which went well. I'll give it another test drive tomorrow morning when it's cold again.
So my little Corsa is suffering from at least 1 misfiring cylinder when it's running cold. This is a very tough issue to diagnose because there can be dozens of causes. Because it's only when the engine is cold and a slightly more common cause is the ignition, I have decided to put in new sparkplugs and cables. It's not too expensive and easy to do myself. Since the car is from '99 the plugs are not available anymore apparently.
These plugs seem to run very well I read so I'm getting these instead. Will put the whole lot in tomorrow...
This was put up infront of Sloterdijk Station today. It was an installation during the 2014 ligh-event here in town. It was showing flags of numerous countries. Doesn't look as much fun as it did then. Wonder what they'll do with it.
