Since I just replaced the Fuel Injectors and Idle Speed Motor, I thought it might be a good idea to check/adjust the air to fuel ratio. I have read some of the threads and watched a video and on my Actron Dwell Meter I connect the black lead to ground (easy) and the positive to the orange wire on the diagnostics plug (difficult). That's the first problem. If I have one, I cannot find it. Then if I don't have one, where do I hook the positive lead to? Second my meter does not have a number of cylinders switch so I guess that fine. And third, not sure the reading should be between 15 - 20 (like the video) or some other reading as mentioned in the threads. My car is #11153 January 1982 if that matters.
