Loss of power...briefly
Here is situation. 1979 300SD W116, if I drive 60mph or more I abruptly lose power where I can barely maintain 50-55mph. this occurs about ever 10-15 minutes. if I pull over and let car idle a minute or three I can pull away with full power for another 10-15 minutes. Like there is a fuel restriction. But main filter has 8,000 miles on it, just replaced the prefilter because it looked dark. Turns out it was dirty outside clean inside. I did a shock of BioBor a week ago, no change, zero debriss making it to pre filter.
Tomorrow I will drive without cap on tank to prove its not a tank vent issue. Any ideas. I though if it was algea I would get debris at prefilter. Car runs wonderful outside of this. This started abruptly a week ago and I see no signs of an air leak.
