When you say hesitant…. do you mean litrally no power or does it just stutter then pick up after?

Could be a few things, Fuel filter, 02 sensor, someone on owners club forums said there exhaust was clogged…. a family member had a similar issue…. was lead problem. I’d say just double check make sure everything is running okay.

Was yours doing the same thing?

Yes, sometimes if i was at a red light and when it was time to take off it would bog down in power until i hit 3k rpms it will stutter then shoot off.
It will be even worse if you wash the car or it rains.

The coil is internal and have the distributor rebuilt. If theirs any other ignition components you have yet to replace get to them as well.

@Rick
I know that I had a hesitation on my car and I had oil in distributer cap. The seal in the distributer had failed. At first it was a small leak then it grew.
