I have been cleaning the body of admission and after arming the car i remain with the high rpm 2000+

Sounds like a vacuum leak. Are the intake hose & valve cover vent hose in place?

ACKERIS250

Yes, everything is well installed.

I do not know if I should place a seal between the manifold and the intake body

Did you remove the throttle body completely? Or just manually opened the butterfly? If you removed it the metal frame is the gasket. Is your check engine light on?

Also the car will idle high when you first start it up if you've disconnected the battery. It takes awhile for it to reach operating temp.

Yes, completely remove the throttle body, but I did not move the throttle, and the engine warning is not activated, but the rpm is 2000 to 1800

Cleaned it because the car began to spend too much fuel and felt without strength
Will this improve your performance?

between the engine block (where the cylinders/spark boots are) and the intake manifold, there is a gasket. Make sure it's not ripped or loose, or that you have a gasket there. It's 3 "8" shaped gaskets with a little tab each.

knyg

no. This will not give you any performance in power.

But this will will let you engine run cleaner.

I think the problem would be in this filter that does not close as it should and the air is filtered,

If the butterfly has moved, is the acceleration body deprogrammed? what should we do

Hello

Remove and clean the intake body again.

I installed it and it seems to be all right the rpm are in 800

Sounds good you fixed your problem. Was the throttle body gasket the issue? Or did you remove the whole plastic intake manifold gaskets? Like the member stated a few post up.

Thank you very much everyone for the help.

I do not really know what the damage was, since I did the same procedure when I put the whole admission body together, but this time I did not stay with the high revolutions

A last problem with my is250, when reconnecting the battery the copilot window does not go down just flashea the switch, I have done all the steps that come out in manual and continuous, check fuses and that the engine works and everything is ok

The ECU has to relearn the idle speed because the obstructions caused by the carbon restricted airflow past the throttle plate. The ECU opens the throttle body to a learned point to compensate for the carbon build up. Cleaning it off allows more airflow and the ECU doesn't know that you have cleaned it off. Letting it idle for a long period or pulling the battery will cause it to relearn the Idle speed control value.
