This is a consistant problem. When I fill the tank, even if I stop a little less than full, the engine starts to perform badly. Pops, won't take gas from idle, pushing down accelerator and nothing happens or takes along time to catch up- , huge hesitation 2nd gear around 2800 RPM, Then can feel it hesitating as I an traveling on flat road. After maybe 10 miles and shutting the engine down and starting the next morning, problem is gone. Dealer has installed air-oil separator and couplling, Mass air sensor, cleaned throttle body. When it is okay the next day, it runs great with absolutely no driveability issues until tank up again. Any ideas would be welcome.
