Idle Speed and Air Temp/Humidity Options

[StarBear]

As getting ready for the 2022 Northeast Gathering, I'm encountering a semi-recurring idle issue on my 1974 1.8L LJet FI. When outside air is cool and dry, idles just fine at 950-1000 rpm. When outside air is warm and humid, after warmup the idle falls off to barely running. I've just been adjusting the air flow screw (maybe 1.5-2 full turns) to open it. Of course, the reverse happens - if I preadjust the screw it idles near 1800 then settles down to 1100 after the engine gets totally warm (15 mins or so).
I presume (?) there SHOULD be some regulation, perhaps with the ECU or AFM, to monitor air temp and humidity and make adjustments automatically? I didn't have to manually do this adjustment in the past.
The AAR works and tests out fine. Just annoying to have to pull over after running a while and adjust the screw. (IMG:style_emoticons/default/dry.gif)

Nope; the day after graduating college in Va. Drove to Ohio two days later for a friend’s wedding then to NJ the after getting back from OH. Broke the car in quickly!

did one xmas in NJ. in a pretty flash area. Bernardsville.
girlfriend's father lived there.

remember getting up early on xmas morning and going for a walk in the snow.
novelty value of white xmas for aussie. lots of deer wandering around.
looked like they would do more damage to your car than a kangaroo if you hit them.

also drove down to trenton once when staying in new york to check out some famous bathhouses that had been designed by the architect Louis I Kahn. the bathhouses were wrecked and in ruin. (IMG:style_emoticons/default/sad.gif)

been to cleveland OH. tough town. or it was back then in the late 80s.

never got to VA. always regretted that i never got a look at that section of the east south of new york.

was actually planning a trip to the states a couple of years ago to catch up with some old friends in LA and Chicago and was intending to finally have a look at that bit of america.
covid put paid to that. probably won't make it back there now unless i win the lottery.
or maybe sell the 914. and that ain't gonna happen if i can ever help it. (IMG:style_emoticons/default/beerchug.gif)
