Hi everyone,
Just wanted to pick your brains on this one..I purchased a w140 s320 limo business edition in august. Great car, which I purchased from a relative. As the owner has passed away, the car was parked up for about 9 months. When I got the car the engine was running rich, black smoke & heavy petrol smell from exhaust. New ngk sparkplugs sorted this.
However, whilst it no longer runs rich, the idle is not perfectly smooth. its no uneven really bad - but just a bit uneven when idling. I have cleaned the maf but no difference. Any suggestions please as to what you think it maybe?
Also gear change can sometimes be a bit rough. The cars has got 120k on the clock, with merc servicing til about 80k, after that a local garage serviced it. I noticed the red tab on the gearbox oil dipstick cover is missing - not sure of oil was changed/looked at, maybe red tab was not replaced.
Any suggestions on how often & procedure on gearbox oil change?
Your help is appreciated...:d
