The car will start and run fine, until it warms up. Normally I can restart it by pumping the gas but after it starts the car won't go past 4,000 RPMs. When I shift. Today it stalled at a stop and now won't even start. Now I had it hooked up to a professional computer a couple codes coming up about bank 1 and bank 2 also brake light sensor. But it seems like it's not getting fuel.

Hi,

When this happens, do you notice any power loss? The EPC (electronic power control) is usually related to a throttle sensor, ABS, traction control, or cruise control.

If you haven't already, I recommend you have the can-bus scanned. CAN stands for controller area network. Basically, the different computers/modules are tied together via a few wires so they can communicate with each other. This type of scan will retrieve codes regardless of the module storing them.

Here is a link that explains how it's done:

Let me know if you have already done this.

Take care,

Joe
