Re: URQ sorting out

Last night I purchased a new meter which is much easier to use and more 
accurate. I did check out all the wires at the ECU connector for continuity 
(all passed). What I found was that the cycle will change. Cold start = 
61.2%. After about a minute it goes to 49.1%. If I manually trip the WOT 
switch, DC goes to 61.2%. Through all this the idle of the car doesn't 
change. I backed out the mixture screw till the idle dropped, and then slowly 
brought it back (removing allen wrench and blipping the throttle to reset the 
plate). The cycle would then drop to as low as 4 and then climb back up to 
49.1%. This was all after the engine was good and warm. A few times when I 
tripped the WOT the DC would go to 61.2% and stay there. The only way to get 
it back to 49.1% was to turn the mixture screw. At least now I know that all 
the wiring is correct, and the computer is functioning and trying to correct 
the F/A mix.
Interesting stuff. The engine _feels_ like I'm getting closer. A down the 
block road test tonight is called for (no plates or registration yet), but 
need to put it under load.
Many of you have been extremely helpful. Thanks
