Car dies while turning

How exactly does it stall, does it sputter out or shut shut off like you shut off the ignition switch ?

Shuts off like i turned the key, just wam, dead.

But the rpm's are already low because im decelerating for the turn and they just seem to miss the idle point.

Just so you know... your battery does not run the car once it's on: the alternator does. It's not the battery cables.

Your IAC may be getting dirty, still working but not responding fast enough. You may want to clean it.

Have you ever tried to run your VR4 without the battery? My old Optima Red top failed a while back and although I got a jumpstart the car wouldn't run and I had to trailer it home. The car kept bucking whenever the ABS system tried to run. I actually found a paragraph in the manual that recommends unplugging the ABS ECU in the event of a very low battery because the ABS system initialization has a very high current draw that the alternator can't support on its own. The VR4 won't run without the battery unless the ABS is disabled.

The battery absorbs surges when it's connected, so it's not recommended to run without it... but yes, the car will run without the battery. The alternator supplies power to the vehicle when the engine is running.

Alternator can't supply enough current unless ABS is disabled.

I'll check on the IAC, see if it's dirty but probably this weekend as I've got some other parts to put on too.

I am just referring to my past experience. My car would act as if I had turned the key when I would make a right turn. I would hop out, go mess with the ground wire, and fire it up until the next right turn. When you start messing with electrical, anything can happen. Just ask a VW mechanic. LOL

The IAC is very simple to test (although my last one that failed tested fine...BUT it would only fail when the car was WARM, and I only tested it off the car (COLD)). It's just a series of resistance measurements.

If I would have picked up on the "warm" thing (I think Steve 92ES mentioned it), I would have tested it while beating on it with a heat gun....

If you need me to send you the section of the manual for testing it, just holler :)
