Mercedes SEC 600 1993
New Owner - Idle Problem

Hello all,

I am the proud owner of a 1993 600 SEC with only 8,000 km! Please see the attached pic. Its a real classic.

However, the car has a problem when idling. It sounds as though its wheezing. The rev needle is always moving up and down as it breathes, both in neautral and in park. The oil needle always stays at zero. I'm sure the needle and the rough idle are related. I also notice that the accelerator has to be pushed down a lot for any real power. I believe all these issues may be related.

I do hope someone can point me in the right direction on how I can try and solve the problem.

Look forward to hearing from someone.

Regards
