First problem, its AC, and AC always robs you of HP. Add a 4 cyl. engine in the mix... has never been a great combo. How long since last tune-up? Fuel system clean? AC check-up? Try the tune-up first and add some fuel cleaners to the gas on the next fill up.

Well I just bought the car two days ago. So I have no idea about recent maintenance activity. It got a new fuel filter before I bought it. When I say drive poorly, I mean it shakes violently at an idle and it extremely slow ar accelerating.

Very cool Redneck, you went into great detail to the few things I asked about. It was the AC that amplified the problem. FYI i've always felt AC puts more strain on the engine then requiered when it comes to 4 cly. cars. Robs you of MPG is what I meant. Sorry. Cleaners were added in case all he runs is regular, which has no cleaners added to the fuel. I've always run premium in my vehicles.

I agree with you Gordon. My ex girlfriend had a 95 honda civic and whenever the AC ran you could feel the difference in engine performance, it really does put a strain on the motor. Also I believe this year honda has a smaller engine, maybe a 1.6 liter engine.

Its a 1.5. Not just performance, but it actually died at a red light yesterday. It'll have to wait a month but I'll be doing a full tune up when funds are available

Well thanks for the detail. I feel I should say that I'm no dope when it comes to actually working on an engine. Its knowing how to find solutions that I lack experience in. That and all of experience is on 23 year 318.

93 dx coupe comes with a 1.5 non vtec motor, its a small under powerd car so when u turn the a.c on the compressor robs the car of power u dont have anything to worry about the car will just drive sluggish happens with every car u just feel it more because your motor is weak thats all
