4g15 throttle body on 4g93?

There is the BISS (Base Idle Setting Screw) that will adjust over the entire RPM range. However it is a global setting, and will cause your overall RPM to change. If you adjust it, your cold idle will go to like 500rpm, but your warm idle will be normal-ish at 1k rpm. There is no easy way to adjust the BISS without ruining every other rpm scenario. I highly recommend not touching the BISS, because its near impossible to rectify it again, but if you must its a philips screw on the top of the throttlebody. Let the car get to your rpm problem range, and then adjust it, and pray that it hasnt ruined your other rpm areas

I'll just have to get the iacv,tried adjusting the BISS fully tightened the rpm is at 2k,if I back it out it goes higher

In a working setup, the IACV should adjust to compensate somewhat for the moving BISS, especially if its fully tightened the car should conk out.

Should I try backing it right out?,what's the factory setting?,I'm starting to think previous owner has stuffed around with everything on the throttle body

If you want, you can try backing it out.

The factory setting is done electronically, thats why i said this lol:

It'll work, the g15 tb is only a tad smaller. Keep in mind it might idle funny without the g93 IACV and TPS calibrated properly.

Got it fixed,got a throttle body from the wreckers it's from a 4g15 but still works and doesn't idle at 2000 rpm
