I've noticed that at about 50 mph and accelerating to that point there is a
very subtle "miss." I guess that's the best way to describe it. Have new
plugs,rotor, and dist. cap. throttle body is clean.also cleaned out idle
control valve.
wonder if fuel pressure regulator could cause this? fuel pump relay?
thanks for your input.

ok. maybe "miss" is not the correct way to describe what's going on.
more of a slight hesitation.
anybody have any suggestions?
I did have the fuel pressure tested and it was lower than normal. .but
mechanic did not seem to be concerned.
