Yet Another Crank/Cam Position Sensor Problem...
Yet Another Crank/Cam Position Sensor Problem...
Yes Another Crank/Cam Sensor Problem...
Alright, Z family... I'm beating my head against the wall on this one.
04 DE Z, bone stock save a Competition Stage 1 clutch (installed by previous owner) and HKS replica catback exhaust.
Ever since I've owned the car, every once in a blue moon on a warm startup, as the RPMs fell, the car would stumble and die. Never was a problem, and it happened so infrequently I didn't think much of it.
Fast forward to a few weeks ago... Took the car in for an alignment and it stumbled and died on EVERY SINGLE WARM STARTUP. As before, it was no problem after a slight throttle blip or 2.
It's also worth noting that there is no CEL.
After some research, I replaced the crank position sensor w/ Ultra Power off RockAuto... Tried this twice. First sensor actually threw a CEL with p0335. Second sensor did exactly what my OEM sensor does, stumble and die on warm startup.
Last week, I tried replacing OEM for OEM. STILL has the same problem with a brand new crank position sensor, and still no CEL. Once running, it runs fine. And the cold start has zero issues.
What am I missing, here...? Should I go ahead and replace both cam position sensors for good measure?
I've done some reading about how the stock flywheel has some type of signal plate (can't find a picture of it), and some aftermarket flywheels have a paint mark that is suppose to match the paint mark on the crank position sensor. Is this something I can see through the hole where the crank position sensor goes?
I'm trying to collect as much info as I can before I spend anymore time underneath that car, so any guidance is appreciated.
Edit: Forgot to mention that I did reset the ECU after each sensor swap (more than once per sensor) via my OBD2 Bluetooth dongle and Torque.
