2000 Elantra cylinder missing

I have a 2000 Elantra. Just recently it acted like it was missing on
one cylinder. This happened once before, but then seemed to correct
itself. I figured I would change the plugs. Sure enough, #3 was black
and not firing. I looked at the wires at night, and didn't see any
arcing. Any idea what could cause this. My next guess is a plugged
injector. Maybe I should run some injector cleaner. Any ideas on
diagnosing. It has been cold here(-10 degrees F)and we keep the car in
a heated garage at night. Maybe it's got water, but I would think that
would affect all cylinders.

 

My guess is you have a bad wire. Just because you don't see arcing does not
mean the wire is good. There could be an internal break.

You can try the computer. Even though you don't get a check engine light
there may still be a code. I don't think it is an injector and, IMO,
additives are just a waste of money.

Does your gas contain ethanol? Many blends do and it eliminates the water
problems because it is like having Dry Gas all the time.

 

It's a worn out piece of shit, scrap it

 

Buy a GM

 

Junk, get rid of it!!!!!

 

I did. It is falling apart so I bought a new Sonata instead of a new Buick.

 

Sometimes it’s difficult to see the marks from an arcing wire. I
usually check for stubborn ones by removing the wires from the plugs
and then setting them back on the plugs without snapping them back in
place. I then start the car and pull the wire off the plug gradually.
A good wire will keep snapping out the end until it’s so far away
from the plug that it cannot arc. A bad wire will start jumping
usually as soon as it gets a little way away from the plug.

If the misfire is obvious, you should concentrate on the plugs, wires,
and coil first. Only move on to other possibilities after you’ve
eliminated those

 

That is too bad (not the buying the Sonata part, but the fact that your
GM fell apart).

My 1994 Chevy pickup has really fit the advertising well (like a rock).
It just keeps going and going and I mean this truck is used as a
truck. I haul firewood with it and plow snow (well most winters
anyway!). I expect it will easily last another 6-7 years and I'll
probably take it off the road when it turns 20. It is just now starting
to show some rust which is pretty amazing given the amount of road salt
that both PA and NY use and I drive about equal miles in both states in
the winter.

I've been very pleased with the reliability of my Sonata, but I have
also been very pleased with my GM truck. I'll buy another one without
reservation.

My '91 Regal was OK. After 16 years it was wearing and needed too much to be
of value, but until the past couple of years, it was a great car. Engine
and tranny were still top notch and performed as well as the day I bought it
150,000 miles earlier.

My '01 LeSabre is not of the same caliber. Too many little things started
going and not covered under warranty. Now that it is the second car, it
will probably last for some time, but it is not going to last long as the
everyday driver. Well, the transmission probably will since it was rebuilt
last year. In addition to the transmission, I spent about $1000 for other
repairs. Plus two of the windows are propped up with wood since they broke.

Fed up with GM, I took a chance on Hyundai. So far, three months and 8800
miles, it has been flawless. So far, I'm impressed. I'll let you know for
sure in a few more years.
