Pulling codes p0335 and p0340. Could this be happening if the timing is off?

Question

Replaced both camshaft and crankshaft sensors. Replaced timing belt. Engine stalls after idling for a few minutes or after driving for a couple miles.  OBD computer is showing ignition timing at cylinder 1 at idle speed varying between 7 and 15.

Hi there,

If the timing is off then it will throw the code for the cam sensor. If you have replaced both the cam and crank sensor and you still have the code then it is a fairly safe bet the timing is off. Especially if the codes weren't there prior to the belt replacement.
