Quick backround of this closing saga; Motor swap with reman motor. Broke old distributor, replaced with reman dizzy.
OK, now with the new distributor in place, I get surging in gear at idle. What did I do wrong? (besides take the job?) I read that the timing cannot be adjusted, however a scan tool is needed to see if there is any crossfire in the cap. Could this be my surging and will it help to turn the dizzy slightly?

v-6 or v-8?
Either way, you need a scan tool to get the camshaft sensor to
0 degrees. The v-8 can be adjusted, the v-6 engine supposedly can't be adjusted, but GM has told us in certain circumstances to enlarge the bolt hole in the hold down clamp so that you can make some adjustments.Just moving the distributor around is kinda fishing in the dark on these engines.
Whether the dist is actually your problem is another discussion.

Dist is brand new (remanufactured), and according to the book, this type of ignition can not be adjusted. The only thing that the book says it to turn the dist slightly to (with use of scan tool during the process) to eliminate crossfire or cross feed or something of the sort. I am going after the dist today and pull it back one tooth on the gear and see if that is where I went wrong. The worst that will happen is that it will not run. And did you mean crank sensor or is there a cam sensor in the system?

From reading previous posts in time, cam sensor is in the dist, computer compares to crank sensor, so if a tooth off will cause problems. But as Ian stated with out a scan tool, its hard to say that is the problem, or that the problem is dist related at all. Whitelightning
Again, v-6 or v-8? In either one, the distributor is nothing more then a cam sensor. If it's a v-6 (4.3) you cannot adjust the distributor unless you grind out the bolt hole in the holddown clamp. On the v-8 engines, you can move the distributor around just like you could in the old days. But....you need a scan tool so that you can see what the camshaft offset reading is and adjust the distributor (cam sensor) accordingly.

It is a V-8, 5.7 The movement on the dist is only about 10 degrees if that much and the base is squared off to accept the hold down.
I pulled the rotor back one tooth and it ran as smooth as butter. SO I have learned that it will run on the mark, one tooth ahead of the mark, and no teeth behind the mark. Taking it over to the shop tomorrow to have the check engine light reset and to check for anything else I may have missed.
Next tool...a Nemisis scan tool.
Thanks
