timing belt positioning for 318i bmw 1997

A high idle could be due to many things but a major cause is a vacuum leak causing too much air to enter the fuel system which in turn causes the computer to overcompensate with fuel. Take it to an auto parts chain store where they will do a diagnostic scan for free and see if any error codes are present.

There are 2 engines used on the 318i. One has a chain the other a belt. The M40B18(1990-1993) uses a cam belt and the M43B18(1993-1998) a chain.

a multitude of potential problems. Probably a bad abs unit or control box $850.00 Could be a sensor at the wheel---dirty or just quit working.

Either way.....lots of money.
