93 Del Sol Si D16Z6 Completely Stock Smog Question
So..I have a quick question and asking for help to figure out how my measurements are so much different from 15MPH to 25MPH on my California Emissions Test...
I have a 93 Del Sol Si, D16Z6 that is completely Stock..
Here are ratings in numbers if you can not see the attached image..
I measured 83 compared to 36, .21 to .08, and 716 to 158 on the 15 to 25 MPH range...these numbers are about 3x across the board.
15MPH(1860RPM) 14.7 0.2 92 23 83 .55 .08 .21 716 194 716
25MPH(2029RPM) 14.9 0.1 57 14 36 .54 .06 .08 764 166 158
I tried to bold, and italicize the numbers that "matter".
Where should I start?

I am just saying, I'm positive the timing is set correctly.
Not sure the age of the plugs/wires, planning to replace plugs/wires soon, and no CEL.
I passed the test, but barely. Really curious in the differences in the measured numbers from 15MPH to 25MPH.

Hook up a timing gun and actually check the timing yourself. Follow the service manual instructions to the tee.
Install basic, properly gapped NGK plugs and replace the old plug wires with OEM.
Check for CEL codes.
Did you install an aftermarket distributor?

NGK plugs and wires will be replaced soon.
Nope, an OEM distributor. No CEL codes.

I definitely appreciate the suggestions sir, and will be taking care of all three tomorrow, not like I'm going to be able to run another test..
Like I stated before, not that big of a deal because obviously I didn't fail, so I am able to go on with the transfer of ownership.
Just really bizarre on the differences in numbers between the two ranges..
