I have read it about 5 times now along with the tdc write up, the diagram I and J tells the story but I just wanted to make sure. measure a 1/2" off the end of the tab, make a straight line, cut the tab off at that line??

Before I cut anything, I would just bring it TDC and scribe a line on the body where the #1 electrode is in the cap and pull the cap.
See that its pointing at the scribe mark.
Grab distributor shaft and make sure its not wobbley loose from a worn bushing.
if this good I would think about drilling a small hole in the TB bufferfly to give it more air so idle is up.
Renix is a strange thing and when all fails improvise lol.

Yes. You're just making an allowance for the distributor to rotate.

Just got finished indexing and no change in low idle problem. When I first started it up it sounded smother and hard start didn't happen. But after it warmed up a little the same thing as before. Any other ideas?? I'm gunna go ahead and block the egr with some tin and bolt it back down just to make sure that's not it. But other than that idk. Might even try taking that bleeder screw all the way out. I've back it out about a revolution and a half and it seemed different in a slightly positive way

Also I was thinking about picking up a ecu reader and I was curious if it would be worth getting? The unit I was looking at is homemade looks pretty legit if it functions well.

Blowing up the thread today lol..but I was reviewing some of the things I have done to see if I had done something wrong, and I might have. I changed the plugs back when I first got it and I was looking at the package of one that was left over (I bought two packs of 4) and they are Bosch iridium and it said the gap is .044. I know it's supposed to be .035. I'm going to get some champion coppers and see if that will change things.

Maybe if you upgraded the coil, but that alone would be a pain on a renix.

Well I had a little break through today!! (Hope so anyway) I ran a new setup for the ccv tube (firewall side) and when I was checking ports and tubes (again) I fired it up with one of the ports unplugged and didn't have an idle drop! It ran for about ten minutes at an acceptable idle. Only after I shut it off I realized that I left a port on the manifold unplugged. So I think for now anyway, I'm going to tap into the air intake above the throttle body and run some filtered air to said port on the manifold and see what it does. More will be revealed but for now I'm feeling pretty good about this

Back out the idle air screw instead.

How is your EGR valve? Is it working correctly, closing off all the way?
Would make a lot of sense if its seeping past and screwing up the idle mixture...
Been reading over the Renix FI manual.
Not much help here except to say ecm uses a preset rpm ....
Other thought i had was a wide going bad between the CPS and the ECM with wrong impedence.

The egr has been capped sense I got it but I am going to make me a little block off plate to completely rule it out. But I was looking at the vacuum diagram and the port that I left off yesterday runs to the air box on a stock setup. (Right under where the fuel pressure regulator line goes in the intake second one down). Why would the iac not adjust when that port is open?? But others it does??

I have a cold air intake And i thought I should get the intake ports and vac lines as close to stock as I can minus the egr and air box
