1G throttle body swap... 1G ISC, or 2G?

Hey, I just finished swapping my Throttle body. My car feels a little rough. I used my 2G ISC... shoudl I have used the 1G ISC instead?

nope, use the 2g.

did you set the BISS screw? Check the throttle cable adjustment? My car idled at about 1300 rpm until I loosened the throttle cable. Then it idled at about 500 so I had to back out the BISS screw.

If that's not it, check your TPS readings if you have a datalogger...

dudn't matter which ISC you use

Cool thanks. I used the instructions on RRE, it also said the ISC's were the same. But in the pics they used the 92 throttle body's ISC.

I thought that it was strange to use a 10 year old ISC vs a 5 or 6 year old one. SO I was wondering if there was a reason for it. But I fixed my Idle problem. I tried to eyeball the TPS position, but that didnt work. The voltmeter method works much better.
