Yes, you have symptoms of ignition break down. primarily plug wires. Double check plug gap & wire gauge (7mm 8mm). Ok, Bosch air meter has two adjustments, using a very long allen wrench (thinking 5mm) insert throu removed plug forward of air boot top of housing. with engine running turn 1/4 counter clockwise, may try several adjust until performance has improved. This IS NOT a fix only a personal diaagnosis temp. this should improve engine performance. The proper fix is lenthy. If improvement is noted then let us know and we will help the permanet fix. Rick

Sounds like there is a load of dirty fuel in that gas tank. Ran good for a while after changing fuel filter, then began to run poorly again. Remove fuel tank, drain and clean out, replace fuel filter AGAIN. That should cure it. Hope this helps

vapor lock or impurities in the fuel system may be clogging the fuel filter also could be a faulty fuel pump

Have you checked the primary gauze filter that is part of the fuel pump located in the fuel tank. You may have got a batch of dirty fuel that has clogged this filter which would cause fuel starvation when demand increases.
