I have a d16y7 and occasionally when I start it up it makes hissing noises. They are low and consistant and they are coming from the timing belt area. I also noticed that I think the motor is shaking more violently now especially at idle. What could this be? Sometimes there is a buring smell as well. I have only noticed this sense it has become cold out and it dosen't always make the noise. Any ideas?

 

If it shakes at idle. Maybe a misfire?

 

Do you have an intake?

The shaking is probably due to the age of the motor mounts.

That's what I thought it was on my Accord. But the shaking stopped as soon as I was driving at normal speeds. It turned out to be a misfire.

 

How do I detect a misfire?

 

???????????

 

Its pretty much just a feel for the sound of one, you obviously noticed something so it could be a slight mis. Major ones would throw a code on your y7. Also how long has it been since a tune-up and when you did one what plugs,wires did you use?

 

I don't know when the last tune up was I bought that car at 96xxx it is now 101xxx miles. What would cause a slight mis and I would I find out that is what the problem is?

one of the ways you can find a misfire is to pull out a plug wire while the car is running.
if it starts to die out then put it back and try another. if you find one that doesnt make any changes after removal that would be the one.

 

it could be a simple thing like a dirty injector or like they said tune up issues. if you never did a tune up it is in need anyway!

I thought it was bad for the dizzy or cap to pull a wire while the car is running. I'm not 100% if it's true, but it's what I've heard.

 

not if you do it for a split second

 

also you pull it from the spark plug not the cap

Never pull the plug wire while the motor is running. If you dont believe me then look up one of the hundreds of threads on here about burned up coils. Besides a misfire doesnt mean that the cylinder is not firing at all it just means not correctly. Trust me if a cylinder was not firing at all you would know. Just give it a good tune-up. Most likely the previous owner did not do one. Get some new wires, cap, rotor, and NGK's and it should fix it right up.

 

what is a cap, rotor, and dizzy?

cap = distributor cap. it sits just to the left of your valve cover and has the 4 spark plug wires coming out of it. The rotor sits underneath the cap. Dizzy is short for Distributor.

Do a basic tune up. Get the cap, Distributor rotor, spark plug wires, NGK spark plugs (thats what honda motors like best) and you should be fine, just like SOHCD16y8 said. When you take the old stuff out, take a good look at the condition of all the old stuff as compared to the new. I'm sure you'll see a hell of a difference. Also, it wouldn't hurt to throw in a new air filter, and maybe a bottle of fuel injector cleaner into your empty gas tank just before fill up.

 

OH yea... and make sure when you put the new cap and wires in, that the wire from each cylinder goes back to its original spot on the distributor cap. label it if you have to, because if you mess that up, you could end up with problems.
