I measured the stock hole to be a 5/32" diameter size. I tired the method of adjustin the set screw, and it appears as if I'm out of range of the reset. I was able to move it maybe 4-5 degrees, then the TPS failed to reset to 0.0 after that. On cold starts my IAC is maxxed out. After its all warmed up its back down to 65 steps.
Area wise I looked at a few options.
Stock 5/32" hole area is: 0.01917 sq inches.
If I used the next size up in my box, which is 11/64", and drilled the stock hole larger I compared the areas. The new area would be 0.003201 sq inches. That is an increase of 21%, which seems too much.
I was thinking maybe an increase of 10-15% area to start with. To obtain this, I figured it would be necessary to drill a seperate hole, and leave the stock one alone.
If I drill a 1/16" hole seperately, I get an increase of 16% total area. Granted this isn't considering the differences due to effective area, but it gives me an idea.
What does everyone else think?
Thanks,
Kevin
