Honda Prelude SI

In my case i adjust my fuel pressure regulator. but that was because i added a walbro 255 Fuel pump. Generally tho there is a throttle body screw that you can adjust for your idle RPM.

There is a bushing that the brake light switch rest against when the brake pedal is not depressed. They are known to break. You can get a replacement bushing from any Honda dealer for around $5.00. Just tell them your brake lights stay on all the time and they will know what to give you.

Need to check vaccum lines a bad throttle position sensor bad map sensor or any other number of things could be wrong with it. You may need to take it to a shop and have them diagnose it with a scanner in order to get the proper diagnosis.

1986-1989 Honda Accord with Carburetor have a very bad habit that is little known even by most mechanics but easily fixed at home. The vacuum port on the choke opener that is connected to the intake manifold and both vacuum ports on the fast idle unloader get plugged up with nasty hard carbon almost as hard as metal. When this happens the choke sticks closed and the idle sticks on fast idle when the engine is cold and nobody can figure out why. All you have to do is attach a small drill bit to the end of a flexible socket-driver extension and put it in a variable speed drill that will let you run it real slow and carefully drill out the vacuum ports that are plugged. After they are nice and clean use a vacuum pump tester to make sure the choke opener and fast idle unloader are working before putting it all back together.

If you have a fuel injected then yes

most cars you have to drop the headliner to gain access to the sunroof module assembly and then either lower it and clean it out or just disconnect the drain tubes and blow them out. making sure they are clear before putting it all back. after your done cleaning the relubricate everything with a high quality grease that's not affected by cold temperature. not white lithium. they make special grease just for sunroofs. the tube I got cost me 30$ at my employee price.

The 3G Preludes have to little rain gutters on the driver and passenger front corners if you open the sunroof up you can see them make sure these are kept clean otherwise you could have leaking problems

Less performance, economy, harder to start cold.

If you are replacing the bulb, the plastic backing (reach behind the fog light) pivots about 15°degrees easily so dont force, and pulls off giving you access to the back of the bulb. Unlatch the small clip and bulb slides out..... With the backing off you also have access to the mount. I have a 1999 VW NB with fog lights and just recently had to deal with them. TIP: The air release hole ends up on top when backing is put back on.

you could try calling a wrecking yard...or a dealerships parts department for the length of a new one...:)

on the intake manifold.

WELL U HAVE AN ELECTRICAL PROBLEM U SHOULD GET LOOKED OUT ASAP BEFORE U HAVE A FIRE.

Best luck I have had is to re-wire the speakers...... It may take some time but, it works. And you can use higher quality speaker wire...

The radiator support on a 91 Accord is a welded on part. Removal requires removing the bumper, headlamps, and fenders. Once these parts are out of the way you must drill out the spot welds that hold it to the frame rails and apron. The new piece must them be fitted and welded in place. On a 91 Accord (and nearly every other honda) the radiator support is a structural piece and should be replaced under the supervision of a trained profesional.

An engine can fail at any time. Also, if your alternator goes, the car will no longer recharge the battery which means that the car could die after the battery runs out of charge.

If you're looking to manually turn off your engine while in motion, the only safe way to do it is to shift into neutral and turn the key to the off position. This can potentially damage the engine, so only do it during emergencies.

1992 -2001 not all models have them anything before that was a 2.0 or 2.1

it depends on the model, if its just the s model it has a H22, a 2.2l SOHC, but the si model has the H23, the 2.3l DOHC, however the h22 is vtec while the h23 isnt, if you are looking at a stock lude anyways.

Around $900 at a Honda dealer for the timing belt & water pump. Head gasket cost depends on if the head needs work or replacement.

You can drive the vehicle. Do not disconnect the battery as this will remove all codes. The problem could be a faulty catalytic converter and the O2 sensor is picking up bad emissions. However, I had that happen and it was the sensor itself that was bad. It could be a loose wire or bad connection due to contaminants. If the Check Engine light is flashing a code that indicates a concern with the O2 sensor, then you'll need to check both the upstream and downstream sensor. The upstream/downstream means before/after the catalytic converter. One common cause is that the connector is loose or needs to be reinstalled to get a better connection. Dirt, moisture, or oil could possibly block the wires from receiving a signal from the o2 sensor. To determine which sensor is a problem, go the your local Auto Zone store and ask them if you can borrow their computer code reader. They will ask you for your driver's license while you use it in their parking lot. The connector on the reader is plugged into the socket under your dashboard under the steering column. Often the socket can be seen by opening the driver's door and looking under the dash/steering column while kneeling on one knee outside the car door opening. Plug in the reader, sit in the drivers seat, and the code reader will tell you what buttons to push. It's easy and if you make a mistake the reader will tell you what to do and set you on the right path for success. After 3 or 4 steps, the reader will indicate whether it's the O2 sensor #1 or #2. #1 is the sensor located in the exhaust manifold, usually accessible via the engine compartment. Try to unplug/plug the wire connector to the sensor out/back in and run the test again. The #2 sensor is accessible from under the vehicle approximately in the area of the driver's door under the car in the center on the exhaust after the catalytic converter. To run the test again you may have to turn the ignition off/on as instructed by the code reader. If all else fails, take it to a TEST-ONLY smog station.

yes as long as it has the same block # if not u have to change ecu

open the hood.. si mean sequential injection... pgm-fi programed fuel injection.... wake up

Open to trunk (boot). Remove the piece that covers the spare tire. Near the front of the car (in the trunk) you will see a metal piece with a wire running into it. Remove this piece and you will have access to the fuel pump.

I'm not sure what you mean here...are you wondering what tire size is on a 1992 Honda Prelude? Or, how do you get to the spare tire? Or, how do you remove a tire?
