No it wont, That Idle dip means you need to raise the BISS screw just maybe .25 to .5 turns. And the oil light is from engine RPM dropping and causing oil pressure to drop, its a mechanical pump and pumps as much as the engine spins, engine spins slow = slow spinning pump = low pressure.

Dont just turn the knob, you have to log your Fuel trims and get them close to zero. With the mod + BISS screw turned out 2 turns from soft bottom, and fuel trims at 0 the car will idle perfect. On a cold start, you'll probably have to stand on the throttle for 10~20 seconds or so.

It works on a 1G also. The BISS screw should only be turned 2 turns out from soft bottom. Do the FIAV valve mod, and if your ISC motor is good and working, your DSM will idle like it did the day it drove off the factory. (once warm) cold idle will be low, so you might have to stand on the gas for a bit.

sounds like it could be fuel cut
