305 TBI troubles
Okay, just the other day my car was normal as can be. Then I go into town. Fill her up with fuel. Now, all of a sudden I've lost my high RPM power. Low RPM power is good but still not normal like it used to be. I replaced the spark plugs, wires, cap, coil, and rotor. Still no power in high RPMs like before. I can still chirp through second. It just seems as if its losing it's power and staying in all three gears way too long. Know anything that could of caused this? My next best bet is to replace the fuel filter..
