I have a 1996 Dodge Neon Highline (SOHC) and it will run fine as long as I have my foot on the gas, but it idle it will just die, it doe not sputter or anything just dies, My check engine light had been on and it was giving a code for the o2 sensor and I replaced that but I am still having the same Idle problem, what could be causing this?

Hello,

This sounds like you might have a faulty idle air control valve (IAC).
The IAC controls the engine idle speed. A faulty or clogged IAC can keep the engine from idling.
The IAC is located on side of the throttle body. Over time large air particles can stick to the inside on the valve and restrict air flow this will impact the way the engine idles.
Many times, cleaning out the IAC can improve the idle quality.

Here are some helpful articles:

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
