1989 560SL stumbles when starting after a warm up
I am new to this forum.
I have a 1989 560SL white on red that I bought back it 2014 from Oklahoma, from the first owner.
The car has 32k miles and is in pristine condition.
Ever since I bough the car there has been a small issue. When the car sits over a long period of time it cranks just fine. When it is fully warm it cranks and runs just fine, very strong! Everything is perfect except this one thing. When the car is warm and I shut it off, and if I am to restart it within lets say 20 minutes, it cranks instantly, half a turn. But if it is to sit lets say for an hour or overnight, it cranks instantly but dies right away. Then with a second crank it cranks instantly and runs like nothing ever happened. All the maintenance is done including all possible flushes, new filters, sparks, wires etc. Non ethanol gas only with clean boost additive.
Ill be honest, I only put about 500 miles for these past 5 years on it. Just don't have time to drive it.
I took the car to the dealer and of course we could not replicate the issue but I also realized that they know nothing to very little about KE Jets.
I would highly appreciate any input on this matter.
