00 Civic DX auto -- Idle problem re-arose...
So two weeks ago, I had an idle problem. (I dont have a tachometer, so I dont know exactly how many RPMS) Basically the idle went up and down as if I was holding down the gas and letting go continuously. A Check engine light popped up and I got the code, It happened to be a IACV. So I cleaned my IACV, everything worked perfectly, fixed the idle problem, and CEL went away.
Heres the bad news... So I find out that I'm leaking oil under my distributor, and research tells me that it is my dizzy leaking the oil. So I mark the dizzy with a screw driver, remove it, change the o-ring but in the process I accidentally flipped the fin (part that goes into camshaft) so basically I figured that since it can only go in 1 way, I switched it into position and put it back in (Is it possible that the turning of the fin can affect my idle?). Lined up my bolts for the dizzy and tightened everything up. I tried to start the car, and no crank, turned out to be a dead battery, so I replace the battery, and now it starts.
The problem is that the idle problem is back, and worse than before. What is the problem now? Vacuum leak? IACV AGAIN? Dizzy? That fin inside the dizzy? timing? battery?
Car: 2000 Civic DX Hatchback
Engine: D16Y7
Transmission: Automatic
Please help me out asap, this car is my daily driver, and Im pretty lost without it. If all else fails, Im gonna have to bring it into the dealership

Theres no CEL as of right now. There was before I cleaned the IACV and Throttle body, and then the problem went away as stated, It wasnt until I messed with the Dizzy that the problem resurfaced.
Im not sure where the vacuum hoses are located... Could you point me in the direction? and I dont see how it could be disconnected either...

Alright thanks for the diagram. However, Something stranged happened... today my Check Engine Light popped up, I checked my code, and it popped up 14, the IACV. Strange because I just cleaned it, along with the throttle body. Now heres where it gets even trickier. I unplug the fuse for FI E/M and the backup radio fuse to reset the ECU and guess what... No idle surging..... Could this fix be temporary? any ideas? Im stumped

If the problem returns, as it likely will, check whether unplugging the IACV affects the idle speed. Also pull the code with a code reader to get the OBDII CEL code.
