Car question

omg don't soak the whole car in wd-40! It just occurred to me that every bolt will loosen simultaneously and the car will fall apart while driving down the highway, like a cartoon!

But until then, every squeak and rattle will have been eliminated.

Thanks for your input, tw.

FYI, the car is a 4 cylinder.

I was reading the shop manual as I was drifting off to sleep last night. Boy, what an annoying book. You find one list that talks about rough idle possible causes, and each cause sends you to a separate section of the book, so you go to those separate sections, and they each send you to other separate sections, so you spend all your time just flipping around from section to section. I need to just sit down for a couple hours with a notebook and take my own notes from this manual, since trying to find where I read something is pretty much impossible. I've got almost every page in this one section folded over.

Anyway, for the O2 sensor, the voltage ranges are supposed to remain within .1 to .9 volts during operation. It doesn't send you a code until the voltage drops below .05 volts, and in my idle test on my car, it never did.

I also have a few stop and go trips around town recorded, but they are confusing because there is so much variation in road and engine speed. I'll try to fit in a short trip on the highway this weekend.

One amusing thing is that this CarChip Pro is also marketed as a way to snoop on your teenage driver and tell you if they accelerate too fast or stop too fast. My wife never triggered the thing, but almost every time I stop when driving, I set the damn thing off. So I come to a stop at a stop sign and the damn thing beeps at me. Then I stop at a red light, and it beeps again. I'm not jamming on the brakes. Honest. But my wife thinks it's funny. There's some way to turn it off, but I haven't figured it out, and maybe it will make me into a "better" driver.
