At times when im driving and i slow down for a second, when i go back to accelerate its like the motor bogs down and wont get any response from the gas pedal. car has high miles, and i just did the water belt and timing belt a month or 2 back (pretty sure this was an issue before that tho), i have not checked the timing with a timing light or messed with the distributor since doing that tho. i have no CEL lights, not sure the last time the spark plugs or wires were changed, o2 sensor on header is pretty new, not sure about if or when the fuel pump or filter were ever replaced
