But Speaking of Worry...

After the misadventure with the pickup truck in Tempe, Lisa mentioned that maybe we would have been better off with the original plan, which was for her to drive the Vanagon to the Bay Area and for us to drive together in my van to Tempe. (This plan was abandoned so I could use the vacation days saved by my flying to Arizona for the Worldcon trip instead.)

Well, if what happened tonight is the harbinger of trouble, maybe not. While powering up the long climb out of Dunsmuir toward Weed and Yreka on I-5, the van was performing pretty well, maintaining 65-plus on the open road, when the SERVICE ENGINE SOON light came on. Now there's not much you can do when that happens because it's unclear exactly what triggered it, so I just kept going. When the road flattened out, the light went out, and then along the next climb, it came on again. It went off again as I slowed down in Yreka for the exit and driving in to the hotel.

The van has plenty of power, but I can think of several possible problems. Among them -- and I don't know if this will trigger the check-engine sensor -- is that I'm concerned that the alternator isn't putting out enough power. Admittedly, I had the air conditioning and lights and radio on, but the needle certainly seemed low to me.

Why do these things always happen on the road trips? Still, there's a GM dealership in Stayton, so I can probably have the van looked over and they can tell me what's wrong while I'm in Mehama. Fingers crossed that this isn't a serious (read: expensive) problem.

On the one hand, if this had turned up a couple of weeks ago, I could have had my regular mechanic look at it. On the other hand, for the past two weeks, I've been too busy to do anything of that sort.

You can also find out what caused it by buying yourself a Haynes or Chilton manual (around $15) and it will tell you how to diagnose the service engine light and what the codes mean. It's a lot cheaper and easier then paying the dealership to diagnose it.

I have the Haynes guide. I don't have the tool for reading the codes, but I guess I could buy one. I'll ask Lisa about it. She's a much better mechanic than I am.

Ah. On my cars it's usually been a case of needing an extra fuse and then just sitting and counting the flashes of the service engine light.

On my 1989 Chevrolet Astro Minivan, you get one "Service Engine Soon" light that comes on solid and does not blink or give any indications. You have to have an extra device (and know where to plug it in) to read the failure codes.

Ah. On my older cars, the "extra device" has always been a spare fuse (the small ones in the front dash) and the spot to plug it in has always been one of the spots in the fuse box. Then the failure codes would start blinking.
