I have a Saab 95. For the last 3 years 3 cranks for a cold start only.

What is your question?

Rest of the day fine. No hesitation,missfires etc. A month ago code P0336 appeared:erased. Today sudden engine stop al low speed and the folllowing codes: P0103 (Maf sensor high input) + P1103 (GM: MAF sensor in range but higher tan expected) + P0335 + P0336 + P0337 (Crankshaft position sensor issues) + P0340 (camshaft position sensor malfunction).....and the car drives perfect. Looks very complicated. Any hint? Thanks
