91 Honda Accord

91 Honda Accord
132 CID, Auto trans, EFI/distributor, engine #MHN2.2V5FNF1
I'm getting a code 42 - Fuel Supply System
The car has a mild shake beginning at about 1800 RPM and it continues through every gear. Feels like it's not gettin enough fuel. Had trouble with spark plug wires and coil. I've replaced plugs, coil, wires, cap and rotor and that all seems to be fine and doesn't appear to have been related to the shaking problem. I've replaced the fuel filter and run a couple doses of injector cleaner but that hasn't remedied the shaking problem. I've run checks on the oxygen sensor too. I'm going to start to check for vacuum leaks and hope that you can give some more direction on what I can check next. Thanks.

Dan if you feel it's not getting enough fuel test the fuel pressure.You must test regulated pressure,before the regulator.I would also drive at the stated rpm with the guage taped to the windshield to test.If its low you have a starting point.How many miles on the car?

Thanks Dave... I'll give that a try. There are 150k miles on the car.
