Hi All,
I have a 1995 E420, every since the fan clutch shredded my rad and had them changed I have encountered a wierd problem.
Probably coincidental.
at first t would start normally, then run for about 10 mins then run rough and stall. then it won't start for another hour or so.
Then recently its giving me a hard time to start, very rough start, then it does the same thing and stalls after a while.
Then today I thought I would check the spark plugs, it had chamion ones, , they looked pretty bad, and there was alot of gunk insife the wire casing for the spark plug, so i cleaned them as much as i could.
So I took it for a drive and it stalled a few kms down the road, and wouldnt start even after a couple of hours, whhen ever I crank it, it backfires like crazy and the exhaust pops loud, but no start.
Seems to me like there is unburnt fuel in the system, b/c when I first started it ( very roughly) you could smell the fuel out of the exhaut, it smoked alot. and if you try to press on the gas the car almost chokes.

any ideas?
