98 v6 mustang stalling when in drive unless gas pressed

[gonzalesjon]

I'm currently having issues when I put my mustang in drive it stalls out. If left in r n or p it idles fine. If I give it gas it will run fine in d and hit into n while stopping it will idle fine. Then I can drive like this but keeping it in drive without revving or driving it will shut down. So far I replaced the iac, the spark plug wires, spark plugs are fairly new, new battery, alternator, water pump, ac. I'm scatching my head and I'm thinking it's either the tps or speed sensor I have some pics please help me the stupid emissions are coming.

Have you checked for codes?
also the pics don't show your car.

I think the pics are screenshots of the [Torque App].

He probably thought they would be useful somehow.

I actually did and no I'm not showing any codes. It's an automatic and I'm wondering if this device I bought that's suppose to help the car run better on obd. If it changed the idle setting for d mode in the pcm.

The only thing that the device does is read registers from the ECU. It is not a tuning device.


I would try pulling codes again:

Once with the key on and the ignition off
Once with the key on and the ignition on
Once right after the thing dies.

When you replaced the IAC did you do a tune? I’d quit throwing parts at until you make sure the timing, base idle, and TPS is correct.
Next I’d open the ECU and check the capacitor’s. That was my problem on my 5.0.

What device?

What device?

It's just a bluetooth interface for the OBD port. It's like this one: Amazon product ASIN B01HXGX8V6View: https://smile.amazon.com/Mestart-OBDII-OBD2-Bluetooth-Car/dp/B01HXGX8V6/ref=sr_1_9?crid=4LMPRLMH1QCC&keywords=bluetooth+obd2&qid=1673484268&sprefix=bluetooth+obd%2Caps%2C166&sr=8-9


All it will do is [read]. It has no capability to [write]. It [will] pull codes though.
