I switched from 93' to 95' wiring, now it won't idle unless I unplug the maf. I'm pretty certain that it is the vacuum lines for the 95' style opti that are giving me trouble, but I can't find where they are, or where they lead to. Does anyone have a picture of where they exit the harness? Any help would be awesome!

There are some pics on my website in the component location views section of where they connect. Here is what a new one looks like. They don't go into any wiring harness.

I don't see anything like that, would these lines keep me from idling with the maf hooked up?

Driving around without the opti vacuum lines won't cause any drivability or idling issues. The cause of your idle problem is related to something else. If it works fine with the MAF unplugged, I'd start by cleaning it.

I sprayed some maf cleaner on both sides and let it set for a bit, hooked it back up and no change at all.

If you started with '93 wiring then the vehicle originally had no MAF. What did you do as far as the PCM? Sounds like it could be a programming issue.

I changed all the harnesses to 95' along with the computer and everything. I do have the AIR and EGR deleted, the lines are plugged, but it isn't tuned out of the ecu.
