I found air sucking from a missing hose on my throttle body. Their are 3 locations on the side, but only the upper and lower has a hose. the middle is missing. I've looked in the HAYNES MANUAL but could'nt find anything.

That hose runs to the EECS (vapor canister) in the driverside headlight well. I removed the EECS and capped that port on the throttle body off so there is no vac leak.

I have an 86 also. Let me know if you need pics.
