hello I’m having weird idle and performance issues
symptoms when car is running cold it’ll run fine but when the car is warmed up the acceleration Seems like it’s hesitating and there is a slight power decrease.
It feels like a single cam at some times
the idle also drops very low maybe 300 and sometimes even lower and picks itself back up.
the idle also has the surging idle when the car has been On drives longer than 20 minutes
Car is obd1

I changed
distributor
spark plugs
cleaned IACV
checked grounds
checked timing on the driver side and everything lines up fine
at this point I have no clue what could be causing it


checked Codes and Got one for IAT and replaced it but still does the same thing
