At cold my car runs with 1100 rpm, and at operating temperature it runs 1700 +

I have NO IRV mounted p.t, due to me ordering a new one home, the old irv didnt work either.


So now i dont know what to do, redo the settings at the butterfly throttle body?

Some tells me it due to "false" air being sucked in by a crack in a hose somewhere but when i take my hand and block the inlet, the car dies, so it shouldnt be this?

Got ANY suggestions what to do?

Normal behavior without any device regulating idle rpm's.
When the engine is cold the fuel doesn't mix proper with the air, and only a part of the mixture burns. When the engine is hot the fuel mixes properly and everything is burned.

Its is? I mean how to i bring the idle down? The irv cant bring it down, unless its open ofc.

oldford

If you bring down the idle rpm without a Idle valve it will stall when cold.
I would use a new Idle valve.

Yeah but how can it brind my rpm down when cold/hot by mounting the irv again mate?

Cuz letting more air in p.t (as the irv does) wont get the idle to fall to normal.
