tracker idle help
I just bought an 89 Tracker, and have been trying to get it road ready. It starts ok, but when at normal temp the idle drops to 300 - 400 rpm and stall out. I noticed that it sounds like fuel being sucked in thru a vacuum line and if I pinch off the line that goes from the charcoal canister to a tee to the throttle body, the Idle smooths out to near normal. there were a couple of lines un-hooked and I may not have them connected right. any help there? also It looks like the bottom port on the canister is connected to a vent for the front diff. that doesn't seem right does it??
I have installed new plugs, wires, dist cap, rotor, timing belt, etc ,etc.
the new plugs indicate rich mixture (very black)
I ran ok when I picked it up, but found that it didn't have a thermostat, so was never getting to temp. it does have a fairly new O2 sensor.
