Car Forum / Hyundai Cars / January 20072000 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. >I have a 2000 Elantra. Just recently it acted like it was missing on > one cylinder.

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.

Many blends do and it eliminates the water problems because it is like having Dry Gas all the time. Buy a GM >>I have a 2000 Elantra. Just recently it acted like it was missing on >> one cylinder.

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.

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. Junk, get rid of it!!!!! >>I have a 2000 Elantra. Just recently it acted like it was missing on >> one cylinder.

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 > I have a 2000 Elantra.
