Car shuts off when A/C turned on...

[Howster]

Hi and thanks for the replies. I have totally cleaned the injectors, replaced the o-rings and caps, replaced the plugs, and so much other stuff I can't remember it all. However it was all done via troubleshooting and not just a way to replace things for the heck of it.

Everything needed to be done as it had not ever been done. I am still concerned as to why the car shuts off when the a/c is turned on. Once I figure that out the rest should fall into place. Thanks.

The AC obviously puts a large load on the engine. The Yaris ECM does not compensate as much for this at idle as most other cars' ECMs do. So, if you are having fuel delivery issues they will be amplified with the AC. You may wan to try pulling the coil connectors and disconnecting the fuel rail and turning the engine over while letting the fuel hose squirt into a container to see what the flow looks like.
