erratic Idle on a d15b2

[HondaPactStudent]

After my engine warms up to normal temp.if i stop at a red light or stop sign my cars idle fluctuates from 700rpm to maybe 2000rpm up an down up and down any body no why? I cant figure it out the engine doesnt sputter or have any problems while driving

Air leak in the intake system somewhere probably- check your gaskets.

my friend had the same problem and was annoying trust me! we finally found a little pcv hose not connected to a canister thingy a kinda big black plastic pump thing. and we bought a new pcv hose and put it on and bam never did it again.

check your (iac/ idle air contol valve) valve on the back of ur intake it could be bad or some dirt got in there.pull it off and clean the screen inside it.

Simple, you got air in your coolant you have to bleed the engine coolant.....^_^
