Problem with rpm

[dani-bayamon]

my accord when this stopped the engine revs down a lot but when I accelerate the engine shows no faults.When I stop down to 400-500 rpm regardless of whether the a / c is turned on or off

Rough idle below 700 rpms? Check your EGR and IACV. Any CELs?

 

[dani-bayamon]

Thanks Varnell, I'll work with it

 

[dani-bayamon]

and wiped the idle and EGR and now my car maintains high rpm of 1000

 

[dani-bayamon]

how I can adjust?

 

[xci.ed6]

that points to a vacuum leak

Did you change the IAC gasket and EGR gasket? That could cause what you have.

 

[dani-bayamon]

First I cleaned the EGR and no changes, the symptom started when I opened the intake, and no, I did not change the gasket

You removed the upper half of the manifold?
