I have a 1998 Honda CRV with an idle fluctuation issue I have cleaned out the (FICV) fast idle control valve on the throttle body I have replace the MAP sensor and I have replaced the (IACV) idle air control valve and the car is full on coolant I have also sprayed starting fluid around all vacuum lines to see if there is a vacuum leak and I have replace the intake manifold gasket as well as throttle body gasket.Any ideas?

 

Did you clean the throttle body?

 

Yes I did

 

Are you sure the new intake gasket was installed in the proper position?

 

yes the codes that the car is throwing is idle air control system P0505 cat system bank one below efficiency P0420 evap emissions leak P1457 and that’s it only thing I can think of is it’s a bad IACV I bought it off Amazon for $50 and Ik there is 4 different ones and idk which one is the correct one to get

 

Get OEM.
