2009年8月4日 · 900 idle is probably too high. A vacuum leak could account for that. On the 330 engines, less than 700 rpm is too low and would reduce low end power to an intolerable level. You have to ask other m43 users to find what the normal idle is. The higher rpm at start is normal.

2023年4月20日 · M43 can be considered more reliable than n42 because it is just simpler (no valvetronic in M43 is a huge difference, and therefore no sensors, retainer springs etc. to break). M43 is made out of cast iron too, unlike aluminium N42.
