87 420SEL Hesitation Problem
Engine bogsd down for 3 - 5 seconds on full throttle acceleration. Normal acceleration car runs fine. Changed the plugs and fuel filter? Both fuel pumps seem to be working all though did not do a pressure test. Any ideas?

Fuel pressure OR fuel pressure differential is the most common problem for hesitation on that car...system operates at 100+psi
