Engine shut off
 

I changed my spark plugs and the valves and when I drive if I come to a stop in gear the engine shuts off but if I leave it in neutral it's fine.... Did I miss something???

You mean it dies if you leave it in gear and release the clutch? Or it dies when you are still pushing in the clutch pedal?

Or is this an automatic?

And what valves did you change?

Changed the spark plug valve seals. I had NGK spark plugs in it before then the new ones I got were just some platinum ones so I just bought NGK Iridium ones so i'm changing those today to see how it does.

Iridium is overkill for the NA engines, but on the plus side they should last half of forever.
