My stalling problem resurfaced today after almost a month of perfect operation. Car was driving fine all day, then I started it up and pulled out of the driveway, accelerated to maybe 20 mph, and it died. I pulled over, tried to start it, and it’ll start just fine, rev up as it starts, and then drop down and die. Did that maybe 5 times, then started and stayed, so I limped back to my driveway.

I’m beyond frustration with this. It has a new throttle body, EGR valve, battery, brake light switch, and a fresh injection cleaning. The fuel pressure is also normal. WHAT could possibly cause such a problem to occur so intermittently?

Unfortunately no, it’s so intermittent that I can never get a pressure gauge on it while it’s happening. The car was completely fine for a month, never showed the slightest hesitation. Then this. I know it could be a fuel pump.

I popped my IID on last night and got a P0513 Incorrect Immobilizer Key. I’d never gotten that code before when this problem happened. Could the immobilizer cause a problem once the car is already started and driving?

thank you! Didn’t know this, good to know that’s a code I should ignore, because apparently there’s a lot of them baha.
