I bought a 1989 CRX (1.5) last month for a buck(100), changed the plugs and fuel pump relay and drove it away, on 2 cylinders though cause the spark plugs were crossed, and drove it all day. After I changed them back it rode ok for about ten minutes then bogged down when ever pushed the gas. I got it home and so far I changed the oil, oil filter, fuel filter, Plugs(NGK Iridiums),Fuel pump relay, the fuel pump, Distributor, intake manifold(and every thing connected to it), Head gasket,got the head worked and shaved,and freshened up the bottom end(minor overhaul,rings and bearing, yes I did hone) and my Ecu is good, ran my boys 90' civic with it. After I Finally get it running it'll get to 5000 RPM's and cut Off, crank it back up and it Bogs down when I push the gas. !CAN I PLEASE GET SOME HELP!

If it's carburated, maybe the carburator's accellerator pump is bad.

For fuel injectioned, check the fuel pressure and flow. (maybe, fuel pump isn't doing it's job.)

Other things to check: bad vacuum hoses, wiring connections to engine (sensors, trottle body, fuel injectors)

If the car has an automatic transmission, check the electrical connections to the transmission (it could also have vacuum connections to the tranny too)

Take Care,

Also, check the fuel pressure regulator. (on fuel injected engines, it's on the fuel supply bar that feeds the injectors; on carburated engines, it's on the side of the thottle body; in both cases, it has a vacuum line and the fuel return line connected to it and there's an o-ring seal to the fuel supply from the fuel pump, two bolts hold it in place)

It could also be a bad idle air control valve, fuel filters, incorrect timing, plugs, wires, distibutor cap, rotor, idle adjustment, etc., etc. Lots of things it could be. Oh, you said you already changed the plugs and distributor cap, so you can eliminate those as the problem.
