2003 Honda Odyssey Question: Idle Surge
My engine surges at idle to about 1100 rpm. It does not always do it. My mechanic has checked everything out and can find no problems. He confirmed that the O2 sensors are good and that the IAC valve is good. There are no fault codes set. It does not matter if the engine is hot or cold when it happens. Any thoughts? - biocrim
Idle goes up and down around 1100 RPM? - nutechauto
Problem solved. It was the power steering pressure switch. It had a faulty electrical connection. - Visitor
A faulty Idle Air Control valve (IAC) can cause the engine to surge and the Check Engine light (MIL) to come on. Replacing the IAC valve will repair this issue.
I own an 04 odyssey ex.lately,I've noticed that every mornning the vehicle's engine Idling surge up and down few seconds after start.It won't stop.does not shows any diagnostic code on computer.wha...
Once the the engine is taken out of park it seems ok
