Idle 306

As I wrote before, there was an idle irregularity in my vehicle, I changed a temperature sensor in an excessive amount of idle group, but for a few days, my idling in both gas and gas drops, especially in gear shifts, from 1 to 2 or 2 to 3, the idle drops immediately from 900 rpm to 200 rpm. and it comes back about 4 months ago, I changed the idling engine, I just did not change the idle group, there is only the haba temperature meter, I would be glad if you could help me with a butterfly in front of the air intake (1.8 16v XU7JP4 INJECTION 2 + 2 1998 model 306) Idle engine approx. 40 ytl air temperature sensor 75 ytl

there is a problem with temperature as far as you tell

the engine temperature sensor was changed, the vehicle froze to normal, but as I said above

I have the same problem, but it starts when I turn on the air conditioner or rear window, my idling normally stops at 600- 650, it seems to me low, but there is no tremor. But as I said, when I open the air conditioner, it keeps shaking between 100 and 600. Idle engine was said, but once it was normal on gas, it was on gas, now it started on gasoline ???
