Civic - Honda :: 2002 EX Reading Misfires On 3 Cylinder And Cat Code
Jul 10, 2014
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!

I had plugs and wires changed to try clear code. Car seemed to do some better but while trying to go up a steep hill car started stuttering and jerking. Power went out of car and check engine light started blinking fast. After let the car sit for bout 45mins car started running fine again and light stopped flashing but remained on. Code read cylinder2 misfire again.

Tried to start my car this morning and nothing .(headlight switch was off),checked the battery and it read less than 1 volt (did return to 5 volts after being disconnected for a while). Drove the day before with no apparent problems or lights. Battery is a die hard gold about a year and a half old. checked pos battery cable to ground read 1.8 ohms went up into the high k ohms when I removed the horn/stop fuse(which was good) .Also after market alarm installed. Am I chasing gremlins or did the battery just suddenly die.

I have a 2002 Elantra that has been in shop 3xs for same thing. The car says it is missfiring on 1 and I have changed wires, coil pack and spark plugs with no success.

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 recently bought my 2010 gti used with 62k miles on it about 3weeks ago. The car had an carbonio intake stage 1 and a stage 1 tune from Apr when I had bought it. On the test drive and for the first two weeks I had it I did not have any problems. A few days ago on a cold start my car threw an MIL and it was flashing. When I got to school I plugged it into the obd2 scanner. Code read P0303: misfire cylinder 3 detected.
My teacher and I went over possibilities of the misfire. Coil pack, plugs , injector, valve float( even tho this should not occur at 1300rpm cold start) we also thought that maybe because the car is direct injection the valve was not closing all the way due to carbon build up on the top of my valves which in this case I'm glad I don't have an interference head. I moved around the coil packs. What is the cause of this? I'm only misfiring at start and when the engine isn't warms up to operating temp.

I have a 1997 Honda Civic that I was given by an elderly neighbor's daughter after the elderly lady went to the grocery and ended up 100 miles away when she could not figure out how to get home. The car was smogged at the beginning of the year but when I got it ran very rough and the temp went nearly to overheating on the drive home when I was stuck in stop and go traffic.I found the radiator fluid level low and an oily residue inside the radiator water bottle. I took it to a mechanic to check it out and was told it had a blown head gasket and maybe worse.
I am thinking of buying a rebuilt cylinder head and replacing it myself but I am not sure how to diagnose if any other damage could have been caused to the engine. It's hard to know but I am guessing that the engine was damaged during the 100 mile road trip due to low coolant level. It turns out short term memory loss was the diagnosis for my elderly neighbor. I filled the coolant level and ran the engine for a bit and the temp stayed normal but the rough running remains. The oil dip stick shows no signs of coolant in the oil and the coolant looks bright green when I looked in the radiator after topping it up with some water.
Any way to detect if I could be facing bigger issues like failed bearings? I am OK to do the head replacement but an engine replacement starts to get into the realm of what it would cost to get another car of the same age.

This is a 2003 honda civic with about 150k on it. Recently the check engine light came on so I went to Advance auto parts to get my codes read. I got back that the oxygen sensor had gone bad and each and every cylinder was misfiring?
What could be causing the each cylinder to misfire like that? I drive it about 60mi every day and it doesn't seem to drive all that rough. So it's kinda weird that it said every cylinder was misfiring, like how could I even drive it like that?
I heard the oxygen sensor is something I don't have to worry too much about. I could still drive it. The clerk told me to some spray carburetor cleaner on it and that should do something for it.
But recently I've noticed that it starts up rough, seems to strain for about 2-3 seconds then it starts.

Replaced clutch master cylinder last week. Now when I accelerate it revs the RPM's and finally catches after about 5-10 seconds. Is this related to the previous repair? They are saying needing new clutch. What to do?

My daughter's 2002 Honda Civic is overheating unless you drive over 60 mph. The heater is also not working - it blows air but the air is cold. It is full of coolant - we checked. The thermostat was replaced about 2 months ago.

I have been driving my 2002 Honda Civic for about 6 years now. For the past 4 years its been all highway, driving 50+miles a day. I have just moved to a small town where its all town driving.
When I would get off the highway before, I would notice a burning type smell, but no smoke and no signs of overheating. Once I moved here where the winter has been significantly colder than what my car is used to, and I am doing all in town driving, I have noticed smoke coming from my engine, but my temperature gauge shows all is well. I have always done regular oil changes etc on the car. I will be making a long trip this summer back home and i am not sure if I should be worried about the car overheating. Should I try and find someone to investigate this problem further or is this just some engine gunk burning as the car gets hot?

I have a 97 Honda Civic Manual transmission and my Check Engine Light Came On. The error code is P0135 which shows up as needing a O2 sensor. My question is:
1. Do I need to replace it?
2. How long do I have to replace it?
3. Will driving with it as it hurt my car?
The weather is getting colder and I read that could be the cause. I really don't have much extra money but I don't want to kill the car. I have kept up on Oil Changes with MaxLife Full Synthetic, Radiator Flush, etc if that matters. I also went into Valoviline Instant Oil Change and they double checked all of the fluid levels and that was OK.

I drive a 2002 Honda Civic. I was driving home from work one day, traveling about 40mph when the car shuddered, the check engine light came on, and I decelerated to 20mph or so. It then wouldn't go any faster than 20-25mph without more shuddering and revving up past 5000rpm. I am able to drive the last 1-2 miles home at low speed without problems. I am able to drive the 15-20 miles to work in the mornings without issue, even on the highway at 70mph. It has been hot in the afternoons (95-100+) and I wonder if the heat has something to do with it. Also, I have an in-dash DVD unit and the screen turns dim/an odd tint from time to time. It doesn't seem to coincide with the other problems. A repair shop said they think it might be a grounding issue.

I have a terrible car. Honda Civic 2002 that runs alright but quakes and shudders after I start it. It also revs up for no reason at all whilst I drive around. Anyway two machanics have told me I have a headgasket leak that will cost a lot of money to fix. Two others have told me I don't or that it is so minor it needs not be messed with. The last one I saw decided I had a bad Coolant Sensor for the Computer.
I guess there is one for the computer and one, um, not for the computer. I bought both sensors and he changed them Friday. Today I took the car out and three times while I was out, my temp gauge shot up into the red hovered for a few minutes and sank back down. It has never done this before. Why this might be happening now? I am really sick of taking my car in and getting a thousand different stories, paying to fix things that are not wrong with it and watching it die a slow death.

I had the oil changed on my 2002 Civic at the Honda garage. They said the pan was badly rusted out and beginning to leak and that the pipe (exhaust pipe?) would also fall apart from rust when they went to change the oil pan. They said it was unsafe to drive in the meantime because the pan is so soft. If the pan springs a leak, I can just pull over and get a tow, right? I hadn't even noticed the leakage, it's minor. I'll take it to an independent garage for an estimate, but what should I be expecting for something like this?And can I safely drive it around town in the meantime?

I have a manual transmission 2002 Honda Civic. Recently when the nights started getting cooler 20's and 30's, my car will not start. The starter will not grind or even click like it's trying to start. All the other electronic devices seem to operate normally, dome lights, head lights, dash lights, radio. Replaced the battery thinking it was the problem. No difference. If I turn the headlights on for a few seconds, the car starts fine. If the temperature is in the 40's the car starts without any problems. The car can sit for days without activities, as long as the temperature seems to be above about 40 degrees there is no problem. As soon as the temperature goes down, the car doesn't want to start again. I was thinking it may be the alternator not recharging the battery enough to give me my cold cranking amps, but before I dig into that mess, Are there places I can take my alternator to and have it tested to see if it is the problem?

02 Civic, 1.7L, 114K Found the front brakes sticking. I popped the bleeder open and got a little squirt out of the left side and a less of a squirt out of the right. I'm in the process of changing the pads which are on order from Rockauto. I took the existing pads off and lubed the pad guides/holding slots but I felt them starting to drag again after a short test drive. Also they did not seem to respond properly with normal braking. How would I test the caliper(s)? It's got to be a bad caliper or master cylinder causing this and I just don't want to throw parts at it.

We have a 2002 Honda Civic EX. Recently we have heard this rattling coming from the engine. It is the same rattling no matter what speed we are at or gear we are in. When we turn the air conditioning ON the rattling stops. What do you suppose the issue is?

I have a 96 Honda Civic CX. The check engine light came on the other day while it was raining (don't know if the rain had anything to do with it) and now it comes on every time I start the car until it warms up. Once in a while it comes back while driving but that's rare. I tried to get the code with a cheap reader and it didn't show that anything is wrong. I then took it to an auto parts place and they used one of their nice readers to scan it and told me that everything is fine. What's the next step?

Okay so let me start off my saying I purchased this car salvaged 5 yrs ago and have been doing extensive repairs on the car, new engine, suspension the works. But started having this knocking sound near my timing belt/water pump. I went into a shop and they said it was the ac compressor and it was going to cost 800 to fix, I said no because it seemed to high for a job like that and I called up my mechanic from back home (NY, I'm working down in NC). He said if the sound gets louder cut the ac/power steering belt since I don't really need it because winters coming up. I cut the belt, the sound is still there. The sound is really loud when I first start it but dies down when the engine is warm and unnoticeable on the highway. Just a side note, the ac belt has been squealing if the ac is turned on/if it's raining out also I am do for a timing belt/water pump change. I have done regular maintenance on this car, every 3500 miles with synthetic oil (spoiling the engine). I really hope I can drive it back up to NY to get it fixed by my mechanic.

I drive a 2002 Honda Civic EX with about 105,000 glorious miles on it. I decided to hit the road and made a weekend road trip to pick up a stranded family member. I live in Ohio and drove Lou Dobbs, my car, to Florida. It was about 950 miles one way. All was well until I got to Florida. I hit my first traffic jam and was sitting with the windows down enjoying the Florida air. Suddenly, the temperature gauge started to climb! It got pretty close to the red but traffic began to flow at that point. As soon as I reached 40-50MPH the temp began to fall again. I picked up my cargo and headed back. Each time I would hit traffic or a red light the temp would climb without hesitation. This is without the A/C running. After I got back to Ohio, i asked a friend who knows about cars. Over the phone, he had me remove the radiator cap and reservoir cap to take a look at the fluid levels. After this though, the car has never overheated! I don't understand. Can air get into the system and I let it out by removing the caps? I can sit in rush hour traffic for a half an hour with the AC running and the needle stays right in the middle. Should I still take it in to be looked at?
