hey guys I have a 97 hatch with a b20 obd2 and the problem is this when im driving every thing

is fine but when im coming to a stop and throw it in neutral the idle stay at 2000 rpm then when

the car come to a complete stop the idle goes back to normal but only when I am completely

stoped why is this

 

Either you have a vacuum leak or you have an air bubble in your coolant system. Or you have a bad EACV.

 

has any one had a similar problem to this I just want some were to start looking

 

if it was a vacuum leak wouldn't the idle stay high and the air bubble in my coolant wouldn't that cause me to over heat but thanks and ill check everything 2night just trying to get things rit but thanks

 

Air bubble would not cause you to overheat.

 

ok well ill be sure to check that wen I get home

 

how do you check if you have a bad EACV
