the map sensor would probably throw a code if it were bad. they do sometimes get gunked up and dont read the right air volume. you might want to check the fuel rail and injectors to make sure they aren't going bad on you. also fuel pump and filter and fuel line, you could have a kink.

At this site I show the relay can be had for $25.00BECK/ARNLEY Part # 2030228 Main Relay( fuel pump) $24.79

A relay has two sides to it-the power feed and the line to the pump is the one side of the relay. The other side is the "coil side"-what makes the relay switch on and pass power from the power feed to the fuel pump wire. The coil side has a signal from one source-your computer-and the other coil side wire goes to ground, usually. When the coil side is activated by a signal from computer, the other side of relay closes contacts so power is passed to the fuel pump.Don't know if a switch will work there, but you could try it. You may need to look at a wiring diagram. If the coil doesn't get a signal from the computer, there may be other problems, like in your wiring or in the computer.

Look for cabin filter, if there is any on a 1990 Accord... not sure... Or make sure you're not recycling air from inside but taking it from outside (option on the heather control). Or air conduit bloked. First three thing to look. Hope it help.

your water pump might have broke I just had the same exact problem the pulley either broke or the blades on the inside

Check your fuses and relays first. The radio fuse also controls the seat belt shoulder harnesses, dash clock, and lighter. Check all your fuses and replace any blown ones. There is a fuse panel in your engine bay and one on the driver's side under the dash near your door

Check to make sure the plugs are tight and torqued to manufacturer's specs. Also, your Valve cover gasket(s) may need replaced.

All I can add is-- why would you drive a caryou just noticed had a leakLet it cool yesFill it yesUse it- no wayHave it towed to a shop maybe

remove both rear light assembly check the globes are the correctway around

Try to turn the steering back or forward little if you feel loose then hold and turn the key.Mai Lor

there is problem with relay PGMFI is under left leg.

here is a site i've used for electrical schematics and they have your year car I checked these are easy to see schematics go to this link http://autoowiringdiagram.com/honda/1997-honda-accord/here is a tip on honda's wiring color codes in the photo i uploaded hope this all helps

Defective window regulator. Replace with new motor and regulator.

On my 1990 Accord Lx I have the same problem.  My floor pan has a hole in it some where and my carpet gets wet which gets my computer wet causeing the "S" light to flash and then when my tranny shifts it skips 2nd gear.

not sure but my holden did the same and it was the crank angle sensor dont no about your car but hope it helps

So, there's a few things to do to fix this. There is the air boost valve, which is on the driver's side of the the intake plenum.. They get a hole in the internal diaphragm, which causes idle surging. Replace it or buy a block off plate from ebay and remove it and block it off. Second is your FITV (Fast Idle Thermal Valve), which is on the front of the same plenum with two vacuum hoses leading to it nearest the driver's side. You can remove the top of it and tighten the seal inside with a flat head carefully until it's fully seated, as that seal backing out causes idle surge. Third is your Electronic Air Control Valve, which is next to the FITV and has a black solenoid looking top. Remove that, pull the gasket off of it and soak it in parts cleaner to get all the gunk off of the screen and passages. Replace the gasket and reinstall. Also clean the throttle body with throttle body/carb cleaner and replace the gasket. After you do all 4 of these and make sure the new seals/gaskets are installed and everything is done right, bleed and feel your coolant system, then disconnect your battery for a few minutes to reset your computer. When you restart the car, let it idle without touching the throttle until the radiator fans come on, which will tell you that your computer is now reset (You have to do this to let the computer relearn the idle pattern.)Here's a link to show you what to do in case any of this confused you:http://honda-tech.com/showthread.php?t=1844067
