So I've had this issue happen twice in the last month. My car would randomly start to jerk at ~3K rpm, and stall by the time I stopped. The first time it happened I had been driving for abour ten minutes and was in light traffic. It happened again today and I was able to pull off onto a side road. The car would start, and if I gave it gas it would stay alive but I could only do that when stopped, trying to drive would cause it to jerk and eventually stall. Both times after waiting about five minutes the car would start up and drive with no issues again. The second time the car threw a CEL for code 24, which is a vehicle speed sensor. Thanks for any input.

Any other type of code? P030x?

Sounds like a tps.

Is the car stock?

No other code, except for one in my AYC ecu for pump failure which is an old problem at this point. Car is pretty stock. I have a few tunes I hop between, a COP setup, uprated fuel pump, 3 inch turboback, intake, aftermarket rad. Not really anything that'd affect this at least.

Hmmm the cop could be a possibility. Have you tried putting in og coils and wires to see if any change?

It happened the first time with the classic 2 pack/wires. I'm kind of leaning towards a cam angle sensor possibly as well. If it was my cps the car wouldn't have even been able to turn over, nevermind run crappy.

Bad cps would cause a crank no start more then likely. I guess you can inspect reluctor wheel for any damage , proper torque. The only way you can rule out both the timing position sensors with with an osciloscope. Other then that it is just blind diagnosis.

Get a buddy with same car and start swapping those sensors. I.e. Tps, map, cps

Main issue is the problem isn't replicable. Its happened twice in the last thirty days under entirely different circumstances.

I know how that goes. Could not verify.
