P0340 code

Asked by jrvs427 Apr 14, 2017 at 11:11 AM about the 2003 BMW 3 Series 325Ci Convertible RWD

Question type: Maintenance & Repair

I've changed the intake and exhaust camshaft
position sensors, crankshaft position sensor, fuel
pump and filter. Car still stalls in the afternoon but
not in the cooler morning hours. I've also checked
the wiring. Any ideas?
