I CAN'T GIVE MY ENGINE MORE THAN 1/4 THROTTLE WITHOUT BOGGING DOWN

1988 Chrysler New Yorker • 6 cylinder FWD Automatic •

New issue with my 88 New Yorker. Runs good however after a while I can't go much past 1/4 throttle and it bogs out, does not die, just bogs and looses power. Replaced fuel filter, set timing as per the manual, and does not seem to be a vacuum leak. Any ideas? I have set timing, changed fuel filter and checked for vacuum leaks.

Correction to the last question. Should read "does not seem to be a vaccum leak".

Could be caused by one of the following below

Oxygen sensor.

Catalytic converter.

Fuel injectors dirty/sticking.

Mass airflow sensor/Airflow meter.

Throttle position sensor.

Crankshaft position sensor

Knock sensor

Manifold absolute pressure sensor.

EGR Valve

Fuel pressure regulator leaking or defective fuel pump.

Fuel contamination.

Foul/defective spark plugs.

Open spark plug wires.

Ignition coil/Coil packs defective.

Incorrect ignition timing.

Cap and rotor.

Note:If it doesn't apply disregard it and keep testing.
