    Welcome, to Motoring Alliance, thanks for joining.

    With that high a mileage, congrats on getting there, I'd start to suspect the fuel system. I'd run a tank or two mixed with a bottle of Techron to see if it cleans things up.

    Ran some Lucas in many times. Once I get past 3200 rpm it takes off like a bandit.
