Hello Team
Re: 1991 500SL, Japan delivery, no cats, no oxygen sensors, no emission controls worth noting...
She starts and runs quite well, (gotta start 2ice when cold), has great power and is an absolute pleasure to drive, especially fast, as she should be...
However on the odd occasion, after driven a short trip (10-20 mins) and stop for a short time (10-20 mins), then try to start again you can hear pinging under the bonnet while turning over, absolutely refuses to fireup and backfires very loudly out the exhaust... Try again and again, 5 - 6 times, same same, sometimes she will start, idle rough for a few seconds and stall...
The beauty of this, is that I leave her alone for around 30 minutes, go back and try, starts and runs as good as always and as if nothing has happened...
Very rarely, while driving, she will idle rough, miss and splutter on the 1st part of acceleration (irons out as the revs get up above 2500 or so) but idle down rough and eventually stall. Try to start and the above repeats itself...
*The strangest of all, this happens on average once every 4 weeks ... Seriously... 4 weeks...
**Aside from a "divorce, does anyone have any ideas ???
