which is cylinder 1 on my '07 sedan?

[canadian_princess]

I just got my oil and spark plugs changed yesterday and now the check engine light is on. Plugged in the obd sensor and I got the code P0301, which thanks to garms code list I found on the forum came up as cylinder 1 misfire. One of the spark plugs were dropped yesterday before installation. When the car is idle it feels unsteady. 500rpm. Ideas? This was the first time i believe these plugs have been changed, at least since ive owned it in Dec (08).

Just looking at the Ignition pdf:

It would appear that #1 is closest to the battery or driver's side in the USA.
However, you might want to wait for the experts to chime in. :iono:

My guess is #1 is the one you dropped.

Replacing the dropped plug with a new one would be the first thing I would do to resolve the issue.

Hmm, just looked at the EWD:
http://www.etimago.com/yaris/repairmanual/EWD.pdf on page 48,
and it shows the opposite. So, don't go by me. :frown:

Number 1 is typically closest to the crank. So its going to be farthest left when looking down at the engine.

That's the one that was dropped. Furthest to the left. Thank u! Keep the info coming!
