Third post I've made about my MS problems, but here we go... I promise I'll stop being a noob eventually... :/


My Idle is at 1400rpm, I'd like it to be lower.
1400rpm idle w/185+ deg CLT and 31kpa MAP

Set up:
- MAT sensor is calibrated properly
- MAP sensor reads correctly
- Timing is on base map, yes base timing was set and tested at 10 degrees BTDC.

Fueling:
- Include AFR target is on
- EGO correction at 15%
- AFR table is stock
- VE table is stock
- No problems reaching target AFRs, even at idle

Idle specific:
- Yes, I sprayed potential vac leaks with wd40 and plugged/swapped out ports/hoses to test leaks
- Yes I checked my timing with a gun
- Yes, I'm in open loop idle
- Yes, my ICV is unplugged
- Yes, spark advance is off
- Vacuum at operating temp is 31kpa
- No surging idle, just high (idle stayed between 1377-1435rpm in log)
- My idle was right at 850rpm on stock ECU, so I really don't want to turn the idle screw if I don't absolutely have to

From what I've read, vacuum leaks and advanced timing cause high idle. I don't see any evidence of either (yes my last post said I had bad MAP numbers, but maybe moving vacuum lines around fixed that idk). Car runs great at all other rpms up to redline.

My question is, what else could case a high idle? Should I just send it and turn the screw? Pls help bro...
