This can make the light come on but so can alot of other things if it is running normal unhook the negative battery cable and let it sit like this for about 15 minutes this will reset everything in the system. If after doing this it comes back on imediately within a few hours there is some problem you should have it checked out to see why the light is on.

Spitting and sputtering like not getting fuel


It may have fouled your plugs, but you can tke them out and clean them. Use a small blade and scrape the carbon off.
You could also take the egr valve off and try to clean it. Use a wire brush. also clean as best you can the passages under the valve, they can get plugged with carbon. Use a new gasket when you bolt the egr valve back down. Keep trying to get the fuel filter off, but the egr cleaning should help.

When the egr valve is bad on a 1992 honda accord wagon what happens?


If it's stuck closed, you will feel no ill effects. If it's stuck open, the car will not idle right and be hard to start. If you're getting an egr trouble code from your accord, test the egr valve to make sure it's working; use your finger to push up on the egr valve diaphragm, while the car is idling....car should shake and shut off if the egr valve is good. The one vacuum solenoid that feeds the egr valve, on that generation accord, is known to go bad and cause the egr trouble code. Check that solenoid if the egr valve tests ok.

Three of your EGR intake ports are likely blocked up and need to be cleaned. The one that's free is receiving too much egr gas and that's what causes the engine to stumble. It's a common problem, but one that's usually misdiagnosed, with that 2.2L Accord engine. Have the ports cleaned out asap or the cylinder one that's getting all the excess egr gas will burn out it's intake valve and cost you much more to repair, requiring the engine head to be removed.

My 1990 Honda Accord had a leak into the spark plug area, and also the tube between the pcv and recycled air intake was collapsed shut. I replaced the head gasket and tube. now i'm getting blow by (oil...


The pvc valve will always let some oil out into the intake to burn. That's normal. Now for the misfire at 2000 rpms, I believe you will have to clean out the EGR passages on your intake system. Basically, three of the four individual EGR passages are blocked up and when the EGR opens, it floods only one cylinder with exhaust gas, causing an extremely lean condition and misfire. It's not an easy task to do on that year Accord, but I think it's what's causing the misfire at high rpms, when the EGR valve opens.

1996 Honda Accord Rough Idle Even After tune up performed Changed spark plugs, distributor cap and rotor wheel along with all spark plug wires, changed fuel filter, air filter, spent $150 on fuel injector...


Perform a valve clearance inspection and adjust if necessary. Tight or sticking valves will cause a misfire or rough running concern. Note: Perform valve adjustment when the engine is stone cold. 4cyl: INT 0.26mm EXH: 0.30mm (V6 engine are hydraulic and no adjust necessary.) Also check for a sticking or stuck open EGR valve. For diagnostic purposes only: Remove the EGR valve. Place a business card over the EGR passage and bolt the EGR valve back on. This plugs the EGR ports and if the misfire goes away the EGR valve is partially stuck open and is defective.
Check for low fuel pressure. Check for low compression. Check cam timing. Check for a weak ignition coil. Also don't over look the possibility of worn or broken engine mounts which cause excessive engine movement and engine vibration. -hope this helps

My 1991 Honda Accord is dropping oil onto the hot cover in the front. Also, the service engine light soon comes on after driving about 10 to 15 minutes. What possibly can be wrong? I think the cover...


You have a bad valve cover gasket. If I remember correctly the spark plug wires go thru the valve cover? If that is true a loose valve cover will leak motor oil on the plug wires possibly causing the check engine/maint light. I would start with the valve cover and a tune up. That may solve all your issues.

Failed emission NOx on a 93 Honda accord ex its papes the 25/25 test but not the 50/50 test. what is wrong how do I fix this? check engine light stays on?


The only thing I can think of checking would be the EGR valve, a faulty cat converter or faulty o2 sensor. Converter shouldn't set off check engine light though unless it is clogged causing too much back pressure, most likely EGR Valve.

The EGR valve helps your car more efficiently and completely burn fuel by recirculating a portion of your exhaust and running it through the combustion process again. When the EGR valve goes bad, it must be replaced.

The EGR valve, or Exhaust Gas Recirculation valve, is a vacuum controlled valve which allows a specific amount of your exhaust back into the intake manifold. This exhaust mixes with the intake air and actually cools the combustion process. Cooler is always better inside your engine. The exhaust your EGR valve recirculates also prevents the formation of Nitrogen related gases. These are referred to as NOX emissions, and are a common cause for failing emissions testing. Unfortunately, your EGR valve can get stuck, causing NOX gases to build up. You'll know if your EGR valve is stuck or malfunctioning because your car will experience symptoms like rough idle and bucking on acceleration.

Here is a picture of where the EGR Valve is located (Accord 1999). Replacing it is fairly simple and straightforward. A vacuum line and a couple of bolts. You'll see what you have to do when you look at it.

If you are replacing the EGR Valve due to the Check Engine Light (MIL) being on with a DTC P0401 then I suggest contacting your Honda Dealer. There was a Product Update Campaign (PUD) in the fall of 1999 that corrected the problem.

Another times, the clean is the solution...I hope help yoiu with this. Good luck, and remember rated this help.
