I was thumbing through my car repair manual and looked up the spark plug gap the manual said “check emissions sticker on inside of hood.”
I did that.
The emissions sticker says spark plug gap 1.1mm (0, -0.1) (note: 1 inch = 25.4mm)
1.1mm = 0.04331 inches
1.0mm = 0.03937 inches
The way I read it:
1.1mm is the upper limit for the gap can wear to
and
1.0mm is what the plugs should be gapped to when they are installed.
(the NGK v-power plugs came pre-gapped to 0.044 which is already beyond 1.1mm, 0.04331 inches upper limit)
Long story short.
-Read the *&$# manual.
-Don’t trust the gap the plugs come with to be correct for your application.
-Funny thing is: I had my plug gapping tool marked at 0.040 which I thought was for a car I no longer have. But, I guess I marked it for my CRX at some point.
I gapped the plugs to 0.040 and the engine is idling correctly again. (no work on engine harness)
Take Care,
Chris
