I have a '98 CLK320 that has run without any major issues for 65,000 miles. Recently, it stalled twice while waiting at a light. After each stall, it would not restart for about 15-20 minutes (until the engine cools down).<br> <br> After the second time getting stuck, I added some oil, and it ran fine for about 2 weeks (thought that was the issue). But then after stopping at the bank, I had the same problem with it not starting for 15-20 minutes.<br> <br> Now, once it starts again, it runs until until the next long stop (turned off or a long stoplight).<br> <br> Has anyone seen a similar issue in their CLKs? If yes, what was the cause (so far an air hose and filter have been looked at and replaced, but it has not fixed the problem).
