There is no adjustment that can be made. You will have to have your iac motor checked it is attached to the side of the throttle body (idle air control).it is operated by the PCM. The PCM adjusts engine idle speed through the idle air control motor to compensate for load on the engine, or changes in coolant temperature or barometric pressure.

2001 Plymouth Neon gets a little hotter than normal when parked or idling, but cools back down during driving

i would suggest making sure you have proper level of coolant in it and maybe go with a lower temp thermostat like a 140 or 160 degree

I have a code for my 1995 Plymouth neon its p0505 with is a idle air control and i can not find any diagrams for what might be the problem could it be as simple as a new air filter??

The air filter has nothing to do with an codes you get.

The PO505 --IAC (Idle Air Control Valve) should
be on the throttle body near the base.

You can remove & clean it or replace

Car idle low stalls out when stopping idles rough

there must be an air leak between intake manifold to the air filter. maybe have any hose not fitted properly.

96 Neon idles a little too low it shuts off

This sound as if it may be the IAC or idle air control valve which is located just behind where the air intake hose attaches to the throttle body. This is a switch that tells the computer how fast the car should idle and adjust the air intake to keep the idle steady. If you go to one of the car part websites you can look up the IAC and see what it looks like for your particular vehicle. Autozone, Checker, Oreiley all have websites.

My neon started idling at 4000+ rpms and wont idle down. car is undrivable because engine revs to high to stop with brakes.

check for major vaccum leaks and it none found then you may have a bad idle air control valve, that controls the idle start there, good luck.

93 voyageur keeps stalling?

The owner should locate the fuel pump first before servicing . prepare the equipment to use in servicing the the fuel pump.The owner of the car should adjust the the Idle. Start the car and check the fuel pump Idle and adjust until the car can drive when it is place into gear.the problem in the car is in the Idle, it means that there is low fuel passing to the fuel pump, that is why the car when it drives or the strength of the car is low when placed into drive. there fore adjusting the Idle until the car will drive when placed into gear is the solution.If the owner don't have time to do it then the owner of the car should go to a car mechanic to do the task or job.

1995 neon stalling and motor problems after left idle ing 10 min

I had a similier issue when I bought a used 95 Neon. Check your spark plug cables for worn surfaces. They like to rub the hood and the valve cover. When they wear down and heat up they discharge to the hood and v/c. This creates low voltage condition that causes the car to nearly die.

Power loss / low idle speed

This could be a multitude of things but my first suggestion would be to change the spark plugs. They are cheap and can be bought at any auto parts store.
