Car Woes
My suby-jet has been running really rough lately. It's loped like mad when idling, backfired often during acceleration, and provided generally a lot less power than I've been used to. I figured it was just the extreme cold and short driving distances that have been experienced lately, but it's been warm (above freezing, in fact!) the last two afternoons and it has still run miserably. So ice in the fuel line was out as well.
I popped the hood and not one but two spark plug wires were unseated. Yeah. That's bad. I snapped them back and they seemed to hold, but it started loping again and lo and behold they were off again. I had bought new plugs anyway as I was planning to replace the old ones. So I swapped out the plugs (one of the unfiring even had cracked ceramic for some reason...hm), and crimped the wires and everything seems to be happy now.
The question is, what kind of damage will having two unfiring cylinders do to a horizontally-opposed 4 cylinder engine? The car still feels way underpowered and lopes every now and then when idling -- could I have damaged a valve? And could any of this explain why the ceramic was chipped from the tip of one of the plugs?
I wish I knew more about car engines, but I guess I'll have some opportunity to learn more when I get the motorcycle...
