P0300 code

Check engine light is back on so I went back to AutoZone. P0300 multiple misfire.
Any advice on what to check first?

This is another thing it does.

Airbag light comes on and the speedo and tach goes dead, other gushes work though.

I had a cylinder misfire on my #3. I replaced all plugs...and I noticed the gap on #3 was about twice what it should be...

Good place to start. I replaced the plugs and wires, cap and rotor about a month ago. I gapped to 032, I had lots of trouble with the #1 plug. Ill pull them all inspect them and check the gap.
