92 Lumina stumble under acceleration
92 Lumina, 3100 has a slight stumble when accelerating or when under load like climbing a hill. Any ideas?

Plug, wire, coil, low fuel pressure, bad o2 sensor, all possibilities.

Re: 92 Lumina stumble under acceleration
Any idea on how to diagnose the problem? It is not giving me any error codes.

Re: 92 Lumina stumble under acceleration
Eliminate bad O2 sensor if no code, check for plugged fuel filter. Relieve fuel press., pull filter and check for sediment coming out of inlet (tank) end when turned to empty into clean glass jar.
