The s light might mean a problem with the transmission computer it is right next to the computer for the car under the carpet. does the car shift gears? if it don't the tcu is burned out ,it is a common problem for 91-93 accords

It is up , behind, uncomfortably up and behind it. Get upside down, legs over the back of your chair, flashlight in your mouth, crazy up in and behind it. You won't find it at a glance. But once you see it, you will stay upside down to get it out. Good luck, and remember, stay cool. Its easy, just uncomfortable.

I would remove the distributor cap and crank the engine over . If the rotor does not turn , then you need to replace the timing belt. The timing belt needs to be replaced every 60 K. If the rotor turns then make sure you have spark to a spark plug. Run a compression test on each cylinder. The basics to run are compression, spark, fuel and timing.

Sorry, about that.

You check cam timing? Also valve adjustments.

Hondas run a "Switch to ground" circuit for wipers. So power goes from fuse to wiper to wiper switch to ground. Check the wiper switch.

There is no specific fuse for the clock you have a bad clock

this should be it

When was last "healthy" tune up? Plugs, wires, all fluids & filters? (especially fuel filter) I'd start there and also run a good fuel system cleaner through it.

Probably your crankshaft sensor

Could be a weak coil or bad ignition module located in the distributor. I would replace the coil if you have not ever done so then the ignition module. The coils last about 150k miles and then can go anytime after that. I've owned four 90's Hondas and they have all had this problem. If neither of those things work then you may have a bad distributor.

IF I HAD TO MAKE ONE GUESS FROM HERE I WOULD BET ON THE TPS , SINCE IT IS ESSENTIALLY A RESISTOR WITH VARIOUS TAKE OFF POINTS WHICH SEND THE MESSAGE TO THE COM AND IT SEEMS TO BE AT ONLY ONE SPEED RANGE THAT WOULD BE MY BEST GUESS BUT AS YOU KNOW IT IS ONLY AN EDUCATED GUESS

Find out what code the CEL is throwing. It could just be that your idle needs to be reset. Or you got the timing wrong when putting your car back together and it's running excessively hot.

should be a idle screw on the throttle body. right next to the accelerator cable. also make sure your cable isn't pulled tight keeping the accelerator opened slightly for a high idle

Nothing ECM controls the idle.

Remove oil pan plug from oil base pan and drain oil. Be sure to have a pail that will hold a min of 5liters of oil to place under drain hole.Once oil is drained remove oil filter and replace.Make sure to use oil to lub up the rubber seal on new filter.Install oil pan plug and fill with oil.Put 3 liters in and check reading on dip stick to be sure not to overfill. Never work on hot engines......You could burn yourself.....Hope this helps.......And always remember to place a block behind and in front of your wheels for safety.
