Engine Stalling

[rock88hard]

Would it rule out water in the gas if I let it run to empty and then completely fill it up?

The top does have some leaks from cracked plastic window and the clamshell not fitting tight. Also, I did have to leave it out in the rain a few days before the problem started.

Check under your drivers seat to make sure the Immobilizer is not getting corroded.
Not sure how that might cause a stalling issue -- but the immob sits in the lowest
point in the chassis and is a magnet for rain water.

If this get's bad enough -- the car will not start, the repair can get pricey AND
if the Immob needs replacement -- it can only be programmed at the dealership.

In other words -- make sure you are not getting your Immob wet regardless
of your stalling problem.

Damn! I did hear a pop 2 or 3 times under or behind me. Usually when I first start it and start driving it. This started only after the stalling problem started.

if the pop sounded like a gun shot behind you, your issue is a check valve located on top of the engine, mounted underneath the intake plenum on the drivers side of the engine, it has a plastic hard pipe that leads to the front of the engine bay and runs down to the under carriage along side other similar style plastic hoses... if your lucky You can test it but having the engine running, and engine cover off, locate the valve and give it a hard smack with the handle end of a screw driver, sometimes itll unstick and cel will go away but the cel will come back usually once the ecu tries to trigger that valve into another position, causing it to get stuck once again.

had the same thing happen to me (1 gun shot sound) and 986 was really under powered and I kept going back to maf and aos replacements till i did some research and made the proper fix.

I replaced the MOFO Battery Cable, and BAAAAAM No More Stalling!!!!!

I might still try to clean the MAF Sensor because the check engine is spitting the code for it, but that throttle body looks like a tedious job where I could mess things up. I couldn't even figure out how to get the hoses off in front of it. So I'll leave the throttle body alone.

It def sounded like a gunshot behind me, but it hasn't since I replaced the cable. It starts fine now. I wonder if it had anything to do with not having enough juice from the battery?

So glad to read this, my car suddenly failed on the highway and started stalling afterwards. I heard a loud short bang twice while starting the car several times. Sounds exactly like what I'm reading here. I've informed my garage on what I read. Let's see what the issue is... Anyway, this is what I like about forums such as these!
