Civic - Honda :: 2002 EX Reading Misfires On 3 Cylinder And Cat Code
I have an 02 Civic EX. Engine light has been on for over a year, runs just fine. Reading misfires on 3 cyl, and cat code. I have since: changed all plugs and coils, changed both front and rear o2 sensors....switched coils around to see if code misfires changed (yes).
I see this is a common problem but no one has a solution..? I'd rather NOT change the cat converter and pay for that only to find out the light stays on. Need to smog so I can sell!
Passat (B5) :: 2002 - Getting Multiple CEL For Catalytic Converters And Cylinder Misfires
Getting multiple CEL's for the catalytic converters and cylinder misfires. Looking for threads that address these particular codes ie. 0431, 0421, 0300. 0303, 0306. I have a feeling that these are being caused from a vacuum leak and/or needing a reflash for the ECU.

I have a 2002 Hyundai Elantra that is exhibiting some strange behavior at idle.It wants to rev from 1500 to 3000 rpm, then back down, over and over again, every two seconds or so. This does not occur when the car is in drive or reverse; it purrs along at a consistent 1200 rpm.It all started with overheating and a water pump change, which was completed and reassembled.Then on startup, we began getting this revving. We double and triple checked the timing belt. We sprayed plenty of carb/choke cleaner in the areas of the vacuum hoses searching for a leak to no avail. Whenever we hookup the OBD code reader, there are no codes.Why does my car want to challenge everyone to a drag race, and what is causing this?

View 5 RepliesHyundai - Elantra :: 2002 - Brake Pedal Goes To The Floor Without Much Force
Working on a 2002 Hyundai Elantra GT. 4 disc, no ABS. Problem is the brake pedal goes to the floor without much force. I bled all 4 lines, but no improvement. Rigid lines from the brake master cylinder to the rear wheels were very corroded, so I ran new lines. The old ones pretty much fell apart when I took them off the car. I also replaced the brake master cylinder. I tried to bleed the brakes again, but couldn't get much (if any) fluid pressure at any of the wheels. Yes, I found a couple leaks at the junction points for the rigid lines, but I re-flanged those connections and got rid of all the leaks. Still no real pressure when trying to bleed.
So, I tried a second, then a third master cylinder with a new attached resevoir. No improvement. I bench bled the snot out of this third master cylinder because the symptoms clearly suggest air was likely trapped somewhere in the system. I used a wood dowel to fully actuate the cylinder many times after all the air had been released while I had short clear hoses running from the master cylinder outlets into a little plastic cup filled with clean brake fluid. I wanted to make sure there was no way air could be in the MC, and no air drawn back in when I released the wood dowel.
Next, I quickly capped off the MC outlets and connected a hose to each brake line individually where they normally screw into the MC. I then let clear fluid drain through each line until it was spilling out clear of each caliper bleeder with no air bubbles. So, no lines are kinked, clogged, or contain air.
I took every precaution to keep air out of the system, yet when I push the brake pedal, there is still virtually no real pressure generated by the MC. The power booster rod is shoving the master cylinder in as it should. I don't think there's any problem with the power booster.
I've used gravity bleeding, manual "push & hold the brake pedal" bleeding, vacuum bleeding, and I'm certain there is no air in the lines or calipers. Still no significant pressure coming from the MC when I push & hold the brake pedal to the floor. It takes maybe 20-25 pounds of foot pressure, but always goes completely to the floor with all the bleeders closed. If the pedal is held to the floor, fluid slowly seeps from the bleeders. I'm used to it spraying when doing this on a healthy brake system.
Hyundai - Elantra :: 2002 - Jerks / Loses Power Briefly
My wife has a 2002 Hyundai Elantra (5-speed manual) with about 185,000 miles on it, which has developed an issue within the last 2 months. The car acts like it is shut off for a split second - tachometer drops suddenly, check engine light flashes very briefly and you lurch a little bit as you lose power, but then after maybe a second, it is back to normal. This has happened while accelerating, cruising down the highway, and idling at a stop sign. The car hasn't actually killed while idling, but is close.
Had it in to a mechanic, and they checked for error codes but found none, and of course it didn't happen while the mechanic had it. On a recent 2 hour trip, it happened maybe 50 times? But hasn't happened for the last week. I should mention that we had the exhaust manifold/front catalytic converter replaced about 3 months ago, as well as a camshaft sensor (those had error codes before we changed them). We've done the recommended maintenance over the years, but are due for another plug/wire replacement (could this be the issue?).
Hyundai - Elantra :: 2002 - Loud Noise From Front Tires
I bought an 02 Elantra last August with 128,000 miles on it. The front tires make a noise at almost any speed that reminds me of a 4X4 with mud tires going down a highway. I have replaced the axles, front struts, outer tie rod ends and one irregular rim, and I will replace the rear struts this weekend. Varying the tire inflation has no effect on the noise. When I got it aligned, the mechanic told me they had to swap the front tires to get the alignment within spec, and the uneven wear should cancel out. That was 3,000 miles ago and the noise level hasn't changed. The front tires still have 5/16 of tread on them. Should I keep waiting it out, get new tires, look for some other cause, see if there's a hole in the firewall I can soundproof, or what?

My Elantra has been doing this for a while: While running (idle, driving slow, driving fast, doesn't matter) the car will lose power and will not respond to the throttle. It does this a few times in a row usually and then starts running normally. When running normally it runs perfectly fine, nice smooth low idle and good acceleration.
I started by doing a basic tune up: plugs, wires, oil change, air filter. No change. I then swapped the throttle position sensor. No change. You can see the symptom on youtube here: [URL] ....
What could be causing this?

View 3 RepliesHyundai - Elantra :: 2002 - Rough Idle And Misfire When Hot / Intermittent Hesitation When Accelerating
2002 Hyundai Elantra GT 2.0L 140k miles
Symptoms:
- Intermittent rough idle when hot, slight shutter, surges between 700-800rmp
- Intermittent hesitation when accelerating, cylinder 2 misfire when hot and under load
- Misfires in all gears under load, mostly when under 2000rpm
- Code P0302 when scanned, no other codes
- Symptoms appeared suddenly, not gradually over time
What's been changed:
- Replaced spark plugs, little or no improvement. Old plugs looked worn, but generally in good shape with no significant deposits.
- Cleared code and swapped injectors between cylinders 1 and 2, after test drive P0302 code came back, so it seems that the injectors are good. If the injector were bad I would have expected the misfire to change from cylinder 2 to cylinder 1.
Inspection and Testing:
- Ignition System Testing
- Spark plug wires and primary coil are within specification.
- Secondary coil resistance is high on both packs. Could this be causing a problem with just cylinder 2? Is it worth replacing?
Spark Plug Wires: Specification: 5.6 Kohm/meter +- 20%Cylinder 1: 2.49 Kohm (Longest)Cylinder 2: 2.03 KohmCylinder 3: 1.64 KohmCylinder 4:1.36 Kohm (Shortest)
Primary Coil: Specification : 0.58ohms +- 10%Actual: .6 and .6
Secondary Coil: Specification: 12.2 Kohms +- 15%
Actual (Cold): 16.03K for Cylinder 2-3 pack and 15.94K for Cylinder 1-4 pack
Actual (Hot): 18.54K for Cylinder 2-3 pack and 18.44K for Cylinder 1-4 pack
Air/Fuel System Testing:Fuel system seems to check out. I do not believe the problem is fuel related. There are no obvious cracks or leaks on the intake manifold. A good spray of Carb cleaner all around the manifold causes no change in idle. I might try propane later. No obvious vacuum leaks.
Fuel Injector: Specification: 13.1-14.5 ohms
Actual: Cyl 1: 14.9, Cyl 2: 15.3, Cyl 3: 15.3, Cyl 4: 15.7
Compression Testing:Compression is not great, but within specification. Could the slightly lower compression in Cylinders 2 and 3 indicate a head gasket leak between those cylinders? Could this cause a misfire in Cylinder 2?
Dry Compression: Specification: 145-218psi, <15psi between cylinders
Actual: Cyl 1: 165, Cyl 2: 155, Cyl 3: 155, Cyl 4: 160
Oil/Coolant/Tailpipe:
- Oil looks normal, not brown or milky
- Coolant looks normal and is full, no signs of leaking (coolant has not been changed in a very long time, could a coolant flush work?)
- Exhaust looks and smells normal from tailpipe.
Sticking valve? How would I check this? Bad sensor somewhere? Doesn't a bad sensor usually throw a code?
Elantra XD (2001-06) :: 2002 - CEL Flashing On And Off / Cylinder 3 Misfire
I have a 2002 Elantra with 123k on it. It has been having issues with poor acceleration, rough idle, surging, and the car just overall shakes sometimes when driving. The check engine light started flashing on and off periodically today, so I coded and it and it gave me P0303, which is a cylinder 3 misfire. I checked the spark plugs, and the cylinder 3 spark plug was pretty bad, so I went ahead and replaced all 4. The wires were in mint condition, so no issues there. I also put fuel injector cleaner in just for good measure. When I went to test the car, startup and acceleration/reverse were better, but the other symptoms still persist. What I should check next???

Our 2002 Hyundai Elantra is having issues. It shifts fine, no need to double-clutch. It stays in gear. Doesn't grind or anything crazy like that. It does seem like it isn't getting power to the drivetrain, and is having trouble climbing hills. This all came on very suddenly. Hubby thinks it's the clutch -- I think it may be the bushings. Though now, I'm wondering if it's something else? Since it's not having trouble shifting, should we be looking at the fuel system? Sensors? Engine seals?

Looking for a rundown on LED versus halogen headlight bulbs, especially output and life? Stock halogen bulbs using 55 watts have a 4000K output, and I notice the Chinese imports' output is 3200-3500K. Does that translate into less bright? Also, the windshield wipers shudder across the windshield a lot unless there's a huge amount of rain--changing to new blades didn't make any difference.

2005 Prius 195k miles, oil changes every 5k +/- 500 (usually minus), new plugs at about 187k, TSBs for coolant loop done, coolant valve for ICE replaced on my dime, replaced aux battery in 2010. Transaxle fluid changed at 100k and 190k due to noise, but that is another post.
I mostly do my own work because, in general, I find dealerships to charge too much (like one hour to change the aux battery) or not competent (like changing the traction battery under warranty but leaving the seat belt behind the panel or not resetting the maintenance light during 5k Toyota covered maintenance)

I drive a 99 1.8t Passat with 90,xxx miles. Yesterday I felt the car hesitate/jerk a little when it's accelerated to 35-40 miles per hour. I've had this problem in my past and it was a cylinder misfire. I would bring it to the repair shop.
My question is: Can my car last about 1.5 weeks? My work is 20 mins away. I can definitely avoid the freeway.
Golf IV R32 :: Cylinder 2 Sporadically Misfires When Accelerating Up To About 60mph
My Mk4 R32 has been in the shop for a week now. My number 2 cylinder began sporadically misfiring on the highway and then once I turned the engine off and then back on it would run fine until I got back on the highway and began to accelerate up to about 60.
Took it in and the mechanics couldn't replicate the code. Got a vacuum tube replaced and and it ran fine until I got to the highway. Same issue.
At this point the fuel injector has been replaced and its still throwing the code.
Accent LC (2000-05) :: 2003 - Cylinder 2 Misfires At Startup
My accent is misfiring at startup, and randomly at stoplights. Pulling the code tells me it's the #2 cylinder. I have no trouble at highway speeds, the car really drives fine outside of stoplights and startups. The idle hovers around 900 rpm. Sometimes, once I'm on the road and driving, the CEL will go away altogether.
My main question is, is there any way to be certain that it's the 2/3 coil pack? I don't want to spend on parts that won't fix anything.
