So I changed the oil, plugs, rotor cap and head, installed a thermostat, air filter, fuel injectors...
Can't get the throttle body off yet ~ the 3rd screw is totally stripped and rusted in. I think I may need to drill and tap if I can't get it off tomorrow.

It idles a little high. Like 1000 / 1100 some times. 500 / 600 other times.
Was around 1100 when I hit the DEQ

It failed at 3.2 CO measured in tail pipe. 1.0 is the limit.
I'm not sure if cleaning the TB will solve the prob. But plan on knocking it out anyway.

What should I be idling at?
In addition to TB, any ideas?

BTW ~ I get great mpg. If that helps narrow the potential causes.
... can a diagnostic computer plug into the old RENIX?

Help I can't get tags till it passes
