1989 Chevy small block V8 350 with TBI and 250,000 original miles
Recently noticed a drop in power. It is most noticeable when I "step on it"- like when passing at highway speeds. Less noticeable in around-town driving. Also seems to crank longer when starting than it used to.
All fluids are regularly checked/changed and are fine.
No unusual noises.
No noticeable engine miss.
No knocking or pinging.
I replaced the plugs, wires, distributor cap, and rotor button about 1.5 years ago.
I am thinking that it may be a clogged fuel filter. I found a filter along the frame under the driver's side door and it looks pretty old. Is that the only fuel filter?
Also, if a new fuel filter doesn't work, should I change the plugs again?
Any other ideas?
EDIT: Is there anything special about the fuel filter or should I just get whatever generic brand they have at Advance Auto?
