vacuum hose routing problem B1in DA9

[GonzoDA9]

If any of you remember, I have a B1 from a 2000 Ls and everything is mostly obd0 besides the intake manifold which is obd2, so finding where these vaccum hoses go is a challenge and I was needing assistance with routing them, I have left the hoses by and under the map sensor located on the firewall with nowhere to go, and the pcv canister on the passenger side Is also lonely with no hoses going back and forth, also have the stock intake hoses on top dangling from their position and I'm pretty sure all of these are judging the idling problem I have, I have plugged up the map sensor on the top of the obd2 intake manifold since I have a obd0 harness, the car runs okay and turns on but it idles oddly and will only allow me to hit a certain rpm before TWO STEPPING on it's own.

Any input would be appreciated because I have been stumped on this for a while, I also drained the gas from the tank and it looked like fat bastards dookie, I'm sure that's a reason why white smoke would come from the exhaust.

you want to probably use the ODB0 ( PR4) intake manifold and head & dizzy... specially if you are running the ODB0 ECU & Harness... makes life easier unless you just go all out to ODB 2 with that ECU Harness, & peripherals.

Well it's also throwing codes 3 5 and 7 all intake problems mostly so I have no idea why, but I am thinking of switching by intake with obd0 but you think I should change out the head too? I've seen this guy do the same swap on YouTube his name was Mrbobgucki or something but he did the swap all obd0 and what knot and it seemed to be running cool, I just have no idea why the revs are acting up the way they are.
