Idling problems 1992 honda accord / in park car idles back and forth from 1000 to almost 3000rpms constantly, in gear it does it only sometimes. wired across the E.C.U. unit under pass. side dash, it gave me a code for throttle position sensor, so i changed out the throttle body intake(because you cant just change the sensor alone). also changed fuel filter, injector resistor,fast idle thermo valve,and IAC valve, tried checking for a code again, now i get no code, but the problem continues, i am a paint and body tech, definately no mechanic, but for a girl i follow a chiltons or haynes ok, im lost on this though

Buy a can of CRC Throttle valve cleaner and clean the idle speed control valve and the throttle bore and throttle valve, this should help.

Why is my 1992 honda accord ex adleing up and down when the car is in park

Your idle air control valve is probably bad. That's what causes a high-low-high idle on Honda vehicles.

Honda 1989 Accord Lxi , 4 door rpm increases and decreases like some one playing with the accelerator after it warms up. it will not do it while in gear so it drives fine, until you go park then the...

This is common on the older hondas, the idle goes up and down, this is caused by a couple of things, you may have low coolant or a bad idle air control valve, the last thing it may be is the power steering preasure switch, this switch is the most common, when you turn the wheel the switch is actived to raise the idle . sometimes that switch shorts out and cause the problem you are having, this switch is located on the powersteering hose, unplug the connector and if the idle stops going crazy then thats the problem.

The idle drops when i put it in gear almost stalling the engine

That is normal, in park or neutral there is no resistance on the engine when you put it in gear there is resistance because the car wants to move. Also when you turn on the ac that turns on the compressor that is run off the belts of the engine so it puts more resistance on the engine. Low idle is not a problem unless the engine dies.

I have a 92 honda accord ex that the it idles go

If it does that when the engine is warmed up (full operating temp.) it may be you iac valve, or your fast idle valve. They get gummed up. It also could be your PVC valve, but probably not.:

accord8.jpg
IAC in red. Fast Idle in yellow. Your PVC valve is plugged into the valve cover (the black hose in between the red and yellow in the picture) it simply pulls out. It should rattle when shaken.
Hope this gives you a start on the problem.

IDLING PROBLEMS ON 1992 ACCORD EX

Have the Idle Control Solenoid Valve cleaned up.

Or it might be defective. See steps below to check...
  1. Disconnect idle control solenoid valve electrical connector.
  2. Disconnect upper hose to solenoid valve from manifold and apply vacuum to hose. Valve should hold vacuum.
  3. Continue applying vacuum to hose and briefly energize valve by connecting battery positive terminal to the black/yellow wire terminal and negative battery terminal to the green/black wire terminal. Valve should not hold vacuum when energized.
  4. If idle control solenoid valve fails to perform as outlined, valve is defective.

near the throttle body there is an adjusting screw(flat head) for air fuel mixture, it's on a deep cavity sometimes with a cover, adjust counterclockwise will increase the idle.
