Generally my '71 280 SL runs great but after sitting and idling for a period of time (5 minutes or so) it will stumble fall over itself when I accelerate. Feels like just clearing excess fuel that may have built up in the piston chambers. After 30 seconds or so of running very rough it smooths right out. Could this be the fuel injectors? I was thinking about having them pulled and doing a bench test to evaluate the spray pattern.
Any thoughts or similar experiences would be appreciated and what was the corrective action.
