those are what i pulled off my car. guess ill keep them around (they were in decent shape) just incase i decide the DMCH ones are not up to snuff.

course if i do decide to change them, i guess its gonna be a PITA to swap them out. fuel mix unit doesnt need to fully removed i take it, but at least unbolted from the manifold to make room for unplugging the wires (the plugs for cyl2 and 4 on the distributor cap is especially crammed under there).

well looks like I fixed the idle.

as seen in the pic (taken before i pulled stuff apart), the lower screw is in full contact with the bracket that the micro switch is attached to, making the fully depressed. I had inadvertently adjusted the throttle assembly rod so when put back together, that lower screw was about 1/8" away from making contact with the plate. so the micro switch was engaging (clicking) but JUST barely.

after readjusting, I fired the car up. quick puff of white/blue smoke (i hope i didn't screw the valve adjustment up) and it idle walked a bit (as it always has) and then settled in where it used to idle.

so with that, Idle appears fine.

now to check dwell, etc this week before attempting a short drive (hopefully)

now i've got a question regarding dwell.
I picked up an Actron dwell meter. i hooked up the meter's green alligator clip up to the Lambda ECU pin in the diagnostic plug (pin #3, lower right pin when plug cap is opened to the right). and attached the neg alligator clip to the grounding bolt ont the top of the intake manifold.

after firing up the car, the reading and my dwell meter just read 0.

any ideas?

There's a 2 pin connector in the engine harness, mine was behind the idle speed motor but you might have to fish for it. One of the wires in this connector is Orange, you can use this for a dwell signal.

I take the dwell reading right off the bulkhead plug to the frequency valve.

ok, onto dwell:

took reading this morning. during the warm up period (idle hunt) the dwell meter stayed right around 21.5 on the 8cyl scale (so 43 when doubled).

once warmed up tho and idling correctly, dwell dropped to 5 (so 10 doubled) and didn't move (let the car run for a few mins and nothing changed. revving the engine via the throttle spool by hand did not change the reading either.

so given this what does it mean i should start checking next?

Do you see 60 with WOT switch engaged

If it dropped to 10 deg. your mixture is pretty far off. The reason it is not moving is your at the limit of the lambda ECU.

I remember the dwell jumps back to a starting position when off the limits.

But don't know if it is in both directions.

Lambda-Probe OK ? and connected ?

Mixture off ?

engaging the WOT switch while idling sends dwell to 50 steady.

i'm also getting some grey/white smoke at idle out of the exhaust and some water spitting out of the tail pipes (but this has been that way since i bought the car.. hoping that's just condensation from running the engine in short spurts)

o2 sensor is connected. hoping its mixture.

at a reading of 5, what way should i be turning to adjust the mix? i know ~1/4 turn is basically the full spectrum in either direction.
