I posted awhile back that i was having idling/bogging issues with my 92 240sx ka24det. The problem went away for a week or so and now its back. The car will do ok when cold but when it gets warmed up and if you get on it all, it starts the problem again. It will idle fine, then drop to around 6 or 7 hundred, stumble 15 or so second then rev up and repeat. It dosent do this all the time but when i notice this problem is when i have the bogging issue. Ive checked the plugs, wires, cap, button, and also done the ohm check on my tps. Also, I have ran seafoam throug the iacv and cleaned the mafs. This morning while the car was idling, it srtarted to stumble and for some reason i pulled out the relay that was for EGI. When doing this, the car idled fine. I plugged it back in and the car started to stumble again. Then I pulled it out and it ran fine. I even drove it with the EGI relay out and it drove great. No bog. Can anyone tell me what the EGI relay does and what my problem could be? I know the EGI PUMP relay is the fuel pump, but what is the EGI relay for?
