My idle has been really fishy lately. It will idle steady at 800 then drop to the lowest point on the tach. More apparent when cold. Or when I put it in gear move about 2k rpm and push in the clutch the idle will fall below 800 to almost stalling a few times then hold steady. I’ve cleaned out the IACV and readjusted the idle. Changed the dizzy cap, and spark plugs are newer.

I’m also getting code 43. I’ve tried a different map sensor and it didn’t help. A bad 02 sensor couldn’t be doing all of this could it

Any help is appreciated it’s a b16a in a eg

There’s no problems starting the car or cooling issues at all
