So I have a 1990 350l that recently decided it didn't want to stay running when it got warm out. When its under 35 degrees, it runs like a charm. No issues, no hesitation, perfect machine. Above that, it will idle for maybe 10 seconds, bog out and die. I wait 15 seconds, start it back up, and same thing. It doesnt make any sense to me at all. I have no idea where to look to figure out where this problem is, or what could be causing it. Fuel is fine, I only use E-free and had the carbs professionally cleaned 2 years ago. Just at a loss.
