Rebuilt ECU, now low idle

[fixkick]

or as some would say what is NOT Bad now.?
30 years of wear and tear.
what is not bad is the real question.
We only see 1 of these cars on the road here per year, just 1, and my wife says, look there, a GEO cracker, (her cute name for it) Saw one Jan 2020. 2dr, ratty.

takes air to run an engine, all EFI cars have resources to supply that, and driver is just holding the key.
