The idle air control valve should be checked for operation both mechanically and electrically, it could be defective. cost depends on which trans you have auto around $230.00 for the part, manual around $150.00 for the part. at those prices I would be darn sure it has a problem before replacement, or find one from a salvage yard in better shape.

Check engine light on and was reading a p0505 code drove to the store and engine like started blinking got home hooked the code reader and now have another code of p0309 and p1399


Code 505 is a problem with the idle air control valve.
Code 309 is noting a cylinder 9 missfire on engines with 10 cylinders which would not include yours. That may be a fluke or not the right number.
Code p1399 is brand specific and for Honda it usually means random miss.
The code 505 could be the idle control valve or a vac leak. The computer can not control idle speed by using the valve.
The miss codes mean the cylinders are not producing power when they should be. Which may or may not be ignition. It could also be fuel or mechanical problems.
If you have not replaced the plugs and done the usual maintenance stuff in the past year or two, I would start with the basics.
Be sure and look at the inside of the dist cap and rotor.

When engine gets hot, idle is up and down with the engine light on. OBD code gives a P0505 code.


per this address "http://www.obd-codes.com/trouble_codes/" p0505 is a "IAC (Idle Air Control) System Malfunction" it gives some good suggestions to look at to find a solution for your problem.

1999 dodge stratus car runs for awhile then dies check engine light comes on code P0505


P0505: Idle Air Control System

There is a small motor that controls the amount of air the engine gets when you aren't using the throttle. The computer uses this small motor to control your idle. It sounds like it needs to be replaced. You can try cleaning it first with some throttle body & air intake cleaner.

When in park honda odyssey revs up and down between 1000 and 2000 RPMs


is the check engine light on also? it sounds like the idle air control valve is bad. this controls the idle of the vehicle. when it is stuck open it causes too much air into the engine and causes it to rev. when it gets to a set rpm, the pcm cuts fuel. then it turns the fuel back on, then the engine revs, then it cuts fuel........code p0505 will prob be set

RPM stays at 1500 instead of 1000 and check eng lght stays on


changing the spark plug will not gonna change anything good in the system if i were you,you might check your idle air control valve if functioning right or check you wires goes to it their are possibilities that it might burned up or you might wanna pull out the idle air solenoid they usually tend to have carbon in it cleaning it may resolve the problem sometimes..
