I'm trying to get the Camry running a bit smoother... any markings or stickers under the hood which would have indicated timing specs are gone. It's EFI, so no vaccum advance or anything. Can anyone educate me on the procedure here?

I also can't find my old timing light, which I'm not sure even works, so if I could borrow one that'd be helpful. Thanks in advance...

I can bring one by tomorrow when I bring your wheel-straps back BTW, you have a PM.

You might have to jump a test plug. See if you can find a factory service manual on line.
There's a timing light in my basement.

I have no idea what this means. Keep in mind none of my other vehicles have a distributor, so this whole timing thing is new to me.

Henry, I got your PM and text msg... Been working too much to reply and won't be here tomorrow but you can leave beer in the fridge.

what he means is that there may be two terminals that you jump with a piece of wire. That is the process with the 22re. Once you jump them, the idle will change, then you will set your timing.

Agreed. Its normally the same terminals that you jump together to pull codes from the ECM.

On GM's TBI/TPI OBDI stuff, there is a wire that leads up to the firewall that needs to be unplugged in order to remove the computer applied advance so you can set the base timing. Eric, Haynes' manuals are not very expensive, and will tell you how to do such things. I personally think that $15 is worth the knowledge they provide. Sorry I didn't mention it earlier, but I figured you'd have bought a manual for it first thing.

The 22re have a separate plug for the check engine light and setting the timing. Look for rubber caps glued to the side of the engine bay. If you have them, the test plugs will probably be lying around the caps or in them.
