Hesitant on acceleration

==================== Your first step should be a tune up, -fuel filter and spark plugs. You might find that you need plug wires as well.

The seller had Bosch Platinum plugs installed. I can change the wires and filter. My main question was of how the fuel delivery system works and whether it has some type of acceleration circuit.

Is it vacuum advance? Could the vacuum line be loose or dried and leaky?

================= There is no "accel circuit". The computer looks at sensors such as throttle position, manifold pressure, egine temp, ect. to determine how much to open the injectors. The closest thing the what you are discribing would be the throttle position sensor (TPS).

check the cat... i had mine clogged with a similar problem.. does it rev sitting still in neautrel?

It behaves the same way. "Normal" acceleration rate and it stumbles. Easy acceleration rate and its smooth. So I would say its not related to load. Are there any other symptoms that could be related to a clogged cat?
