So I'll start the car in the mornings, drive it down the road. Almost like clockwork it will want to die at the first stop sign. It will never die or struggle while I'm using the gas, only when in neutral. I can save the stall by feeding it gas, and it will even out. It will continue to struggle while idling until 5 minutes has gone by, then it idles amazing! I'm out of ideas. If it struggles while idling why doesn't it struggle while on the throttle?

I've replaced: Plugs and wires, ignition coil, cap and rotor, air intake temp sensor, fuel filter, cleaned the IAC valve.

Thank you so much!

Just blow through the first few stop signs for 5 minutes! Kidding!

You can manually relearn the Idle by following the procedure below.

1. Remove battery power for one (1) minute. Restore battery power and place air conditioning controls (if equipped) in the "off" position.

2. Firmly apply the parking brake and block the drive wheels. Start the engine, shift the transmission to drive for automatics and neutral for manuals.

3. Allow the engine to run until the engine cooling fan has cycled once, or a maximum of 10 minutes.

4. Turn the ignition key to the "off" position for at least 5 seconds.

5. Repeat Step 2.

6. Allow the engine to run for at least five (5) minutes.


The correct IACV values for proper idle control will now be stored.

Good luck!
