Spark plugs

With an August road trip to Calgary in the works, I've been trying to get my car fixed up and ready to go. Basic stuff, oil change, tire pressure, etc. I'm sad to say that I've been particularilly negligent about tire pressure. My bad; that's poor fuel economy, increased wear, and increased squeek! They should also be rotated probably....

Today I changed the spark plugs. I don't even know when the last this they were changed was. They probably have over 80,000 km on them now. That's about 30,000 km over the recommened change interval of 50,000 km.

Since the car stumbles a bit at certian RPM ranges, and ocassionally knocks, and burns oil, I was curious as to what the plugs look like. They all had excessive gap. Two were oil fouled, indicating worn piston rings or valve seals, so it's especially no surpirse that it burns oil. The other two were just old. So hopefully new plugs will help a bit. I should probably also measure the wire resistance...

Other things on the list are fuel filter and battery. The guy who changes my oil recommended these, saying that the fuel filter looked like the origional equipment. I have records indicating that it was changed at about 100,000 km, so it's probably ok. The battery will need to be replaced before winter though.

Other than that it is running ok. It should be able to get us around until we get real jobs!
