Elantra XD (2001-06) :: Hesitation When Given Gas And CEL Came On - Misfire On Cylinder 2
2001 elantra 167000 miles, started a hesitation when given gas and check engine light came on. After hesitation rpms go up it runs good. Code is # 2 cylinder misfire. I have changed plugs, ignition coil and ran seaform into vacuum line and tank. Still no change. Could that 1 injector be clogged.

My car is misfiring, as in acceleration 90% sputters until I lay the pedal to the ground, which obviously isn't good for my gas. What do I do? I can't find anything online and I don't want to be throwing money into things that don't work.
View 4 RepliesElantra XD (2001-06) :: Random Misfire On Cylinder 2 / 3 And EVAP Codes
Trying to troubleshoot my 2001 Elantra (173k). I'm having intermittent trouble codes being set and I'm wondering if they may be related:
P0302
P0303
P0446
The cylinder 2 and 3 misfires are relatively recent. Plugs and wires are visually ok (and not that old). I swapped plugs 1 and 4 with 2 and 3 to see if the plugs are bad. It took 3-4 days, but the P0303 set again (and it's very intermittent - car will noticeably lose power for a few seconds, code set, then run fine for several days). I also sprayed carb cleaner on the intake manifold gasket with no change in engine idle, so the gasket appears to be intact.
I had read in a forum somewhere that the misfires could be related to a vacuum leak, which could also be setting the P0446 code. I removed the charcoal canister and inspected the lines - visually ok.
I bench-tested the canister control valve and it did operate, though I noticed some charcoal blocking the valve so it would not close all the way when energized. I used compressed air to blow the debris out of the valve and it appears to close properly now.
I went to hmaservice.com and noticed there are no instructions for the P0446 DTC. I've been using a Haynes manual instead. For quite some time now when refueling, the fuel nozzle shuts off every few seconds (I have to slowly put the fuel in to avoid).
Some questions:
- Can these codes be related?
- Based on my symptoms, should I replace the canister control valve? What about the charcoal canister and the charcoal air filter - should those be replaced as well?
- What else should I check?
Elantra XD (2001-06) :: Cylinder 2 Misfire / Rough Idle Especially After Fill Ups
I have a 2001 Elantra with 170K miles. well taken care of. I've been having a rough idle issue for some time now. The car idles very rough. I checked for codes and I got the cylinder 2 misfire code (P0302)...
I started out and replaced the plugs and wires, no solution...
I replaced the coil packs, no solution...
I replaced the MAP sensor, no solution...
I figured it may be no to low compression, so I did a compression test and all cylinders came back normal, still no solution...
I figured it might be a dirty injector, so I poured some seafoam in the gas tank, and no solution...
So my next step is to switch out the injector. Is there anything I am overlooking?
Here's the big thing that is happening too... Everytime I fill up the gas tank, I turn the car on and it idles even rougher. Like if you talk while sitting in the car, you sound like Chevy Chase when he is on the vibrating bed with Beverly D'Angelo in the movie vacation! LOL. It slowly goes away after 10-15 minutes of driving. All this rough running engine ONLY happens at idle, otherwise it runs very smoothly.
Elantra XD (2001-06) :: Check Engine Light (cylinder 3 Misfire)
As the title says I have plugged a code reader in and it says "cyclinder three misfire". So I pulled the plugs and good god they were nasty. Some having a gap of 80-90 thousandths of an inch. So I figured the plugs were the source of the problem, thus I replaced them but to my dimise the check engine light is still on, and still reading the same ol' "cyclinder three misfire". I have put 350 miles on it in 24 hours of changing it to allow for proper time of the circuit cycling for the light to change but not sure if it takes longer...?
I also went ahead and checked the plug wires resistance when I had the plugs pulled and they ranged from 1.5-2.5k ohms shortest to longest (cylinder 4-1). And if your curious the magic cylinder three was around 2k ohms for however long that wire is, my guess would be 18 inches. Would this be out of tolerance, I know the norm is 10k ohm for every 12 inches or so...?
My next guess would be replacing the power pack or I guess you car guys call it the "ignition coil"...? I will say that the car does run much smoother after replacing the plugs.
Elantra XD (2001-06) :: Misfire - CEL Flashing When Give A Lot Of Gas Like Taking Off From A Stop Light
I have a 2003 Hyundai Elantra standard model, Manual drive.
It started out with the CEL flashing sometimes if I give it a lot of gas like taking off from a stop light. Then the car would just lose power when I was driving randomly and cut off like I was running out of gas. Then I restart it a few minutes later and it would drive fine. Then it now got to the point that when you try to drive it, it just shakes a whole lot and it has like 20% power, you can hit the gas as much as you want and it pretty much doesn't move.
The first time I had it towed home I replaced the Ignition Coil, and Spark Plug Wires which did nothing.
The first shop I took it to said it was a bad injector and bad spark plug wires (even though they were new)
So they changed the injector and wires and the car ran fine for 2 weeks at most and started doing the same thing. When I took it back he said another injector went bad and that they were all going to go bad in sequence. So I had him replace that one and it drove perfect again for a week and had the same problem.
Then I took it to another shop which said my spark plug cables were arcing inside where it plugs in so I took the cables back and got replacements and he said they were still arcing and were garbage to get cables from the dealer so I did that and it ran fine for an hour after taking it home and just started like it was running out of gas. I would have to floor it and basically coast, and try to restart it and when I would give it gas it would hardly go and I just had to keep restarting it and finally it wouldn't start so I towed it home, and sure enough after cooling down it started again and now when you drive it, it feels like you've only got 20% of power.
The only preexisting condition the car had was a clogged charcoal canister because when I get gas it always keeps clicking and I have to put 30 cents of gas in at a time or the nozzle shuts off or if I keep doing it too fast the gas comes out and runs down the side of the car.
I changed the spark plugs I think about 2 weeks before this stuff started happening. So far it has new:
Ignition coil
Spark plugs
Spark Plug wires (x2)
Fuel Injectors (x2)
Hollowed out Cat Converter because the mechanic said it was clogged

View 1 RepliesElantra XD (2001-06) :: Rough Running With Low Power And Flashing Engine Light - Cylinder Sparks
I have a 2001 elantra 2.0 gls. It is running rough with low power and flashing engine light. It may have a bad 02 sensor but when checked for spark only the 2 and 3 cylinders were sparking. I can confirm this because when I unplugged the 1 and 4 spark plugs it made no difference in the way it was running. Next I tested the resistance on the coil packs. Both were an even 1.5 ohms. How can it be that the coil packs are good yet the plugs aren't firing? I also have moved plug wires around and have had no success.

I have a 2002 Santa Fe 4 cyl that is giving me a problem that I could use some advice on tracking down & fixing . First & most important is a code P0302 # 2 Cyl misfire. How to check the ignition coil pack , injector ,& wire for this cylinder in home garage with normal tools & meter . Is there a you tube displaying how to do this step by step ?
The other problem which I don't have the code for at this time is that some part of the exhaust is not getting warm enough & this also put's the check engine light on . Will get back on this one when I solve the main problem Misfire.
Passat (B7) :: Flashing CEL - Cylinder Misfire At 50K Miles
Today I started up my 2013 Passat SEL up and it started shaking and idling very strange. A few seconds later I had a flashing CEL so I decided to turn her off. I waited about 5 minutes (after cursing for about 4.5 if those minutes) and tried again. This time the car started and everything was fine, no CEL, no other issues. I drove for about 10 miles, shut off the engine and re-started about 5 more times with no issues.
I just had the car in for the 50K mile service at VW and everything checked out ok. I copied the VAGCON report below and I also sent it to my service manager to get his opinion. What I should do?

Golf IV / Jetta IV :: 2004 - MIL Flashing - Misfire On Cylinder 4
Just dug out my 2004 2.0 Jetta after sitting buried for 4 months. You can see a corner of the wheel there lol, its been a LONG winter. It is my car but my brother normally drives it, and while he is away at uni it just sits.
Anyways, dug it out to start it. Started right up, however after a bit the MIL began flashing. It was running a little rough. Took out my code reader and engine misfire cylinder 4 came up. The rpms are varying by 75~100 every few seconds, however nothing rough. It seemed to rev fine.
Before I put it away I got my brother to put some fuel stabilizer in the fuel. He now tells me that he put some in the oil too since it said "oil stabilizer" as well. It was a seafoam type brand... Not impressed with him there.
My question is could this just be the car waking up? Should I let it run for an hour or two to see if things work out?

I have a 2008 Hyundai Accent that is giving me one heck of a headache. I keep getting a code for number 1 cylinder misfire. When you start it up it runs fine for a while then the CEL will flash and it will start running rough. As soon as I shut it off and restart it, it runs fine. I even experimented with it this morning on the way to work. It started running rough doing 60, I put it in neutral, turned the car off and then right back on, put it back in gear. It ran fine the rest of the way to work. I have swapped coil packs, fuel injectors, spark plugs, and have even hang tested another ECM. Still number 1 cylinder misfire.
View 8 RepliesAccent MC (2006-11) :: CEL Flashing / Rough Idle - Cylinder 1 Misfire
I did not get the specific cel code but its what the guy told me at autozone.
Long story short. Washed engine, let sit for about 30 mins. Car started with flashing CEL and was "puttering" and very rough idle. Drove home took intake off and replace with stock, took spark plugs out and they were not wet. Then let it sit for about 15 mins. Started just fine. No CEL at all.
The accent saved the CEL and the guy told me that Cylinder 1 had a misfire.
My question is, should I do anything now even though the car seems to be running ok?
Ford Ranger / B-Series :: 2006 XLT V6 - CEL Flashing - Cylinder 2 And 3 Misfire
Been awhile since I've been able to post but I've got a serious issue with my 2006 Ranger XLT 4L V6. So last night about 2 miles from home my check engine light started flashing like it was a at a rave and my engine wasn't acting right, also had the STRONG odor of raw gas, no other lights from the dash, no fluids leaking, oil was good n nothing in radiator but coolant. Was able to baby it to my current home but all my tools are in storage so had to wait to get my ODB scanner to see what's up. Scan came back as 'cylinder #3 misfire' & 'O2 sensor reading rich'.
Go cylinder #3 spark plug out and it were fouled bad. Got ride to the store and got a whole new set. Got back n got'em changed and fired ut up, idle still rough and check engine started flashing again and white cloud coming from exhaust pipe and STRONG odor of gas. Check and now have 'multiple missfire', 'cylinder #2 misfire' and 'cylinder #3 misfire'.
Shut it down go and double check ALL spark plug wires are connected and TRY to start, get about a turn n a half then starter spin. Try again and the engine won't even turn over. "Great I've seized the engine!" Was able to put a socket on the crankshaft pully and manually turn the engine over "whew didn't seize the engine", did this a couple of times and tried to start, was rough but eventually it fired up, still idling rough and again check engine light flashing, while it was running I pulled one plug wire at a time from the coilpack to see/feel the lighting and there was spark for the 3 I pulled, didn't affect engine idle.
Run codes and 'cylinder #3 misfire', so now that the engine is was warmed up I pulled out my ohm meter and started checking wire resistance. Cylinders #1, #2 were at .012, #3 was .011 and #5 was .009.
I've figured that the raw gas is due to cylinder #3 not burning and just pushing gas into the exhaust. So to the brass tacks, do I invest in a new set of wires? Or could it be the injector being stuck open and just flooding the cylinder? No when I originally pulled the #3 plug fuel did not spill out. Haven't pulled #3 again due to it being May in Arizona and had to take a break. I'm going on the assumption that the engine wouldn't start after a short run do to "hydraulic lock in cylinder #3", my manually turning the engine over cleared this and allowed the engine to start.
1996 Blazer - Flashing Cel Light P300 Multiple Cylinder Misfire?
So my 96 blazers cel started flashing and the truck started running extremely rough. I changed the catalytic converter and the o2 sensor that is in the pipe. Made no difference. So I knew my intake manifold gasket has a leak so I changed the gaskets and put knew bolts in. I wasn't thinking and took my distributor out and forgot to mark the timing. So played like heck getting it in timing again. Took a bit cause I didn't realize there was two timing marks. So got it started again was running really rough so thought 180 off turned it nothing. So put it back started it up still running very rough and flashing cel so put a new crank sensor and cam sensor in and a ignition coil in. No dif still. Could it be the egr or ECM?
View 12 RepliesAudi - A6 :: 2004 - Check Engine Light Intermittently Flashing / Misfire On Cylinder 2 And 5
I have a 2004 Audi A6 wagon that has an intermittently flashing check engine light. I took it to the dealership to have the codes read and they told me that they got codes for Cylinder 2 and Cylinder 5 misfires. Additionally they got a code saying the Engine Coolant Temperature Sender was electronically faulty. What is this part and what does it do? Is it essential to fix it immediately?
The dealership recommended changing the spark plugs and the air filters for the cylinder misfire issue. We are also talking about replacing the timing belt since the car has 105k miles on it. I know there are several other parts that are replaced during the timing belt replacement (like the water pump, thermostat, oil seals, etc). Is it essential to replace these items if there is no immediate need to do so?
Toyota - Corolla :: 1999 - Check Engine Light Came On Flashing / Cylinder 3 Misfire
I have a 1999 Toyota Corolla. 4 cylinders.
I was on the road about 2 hours from home when my check engine light came on flashing. It stopped flashing so I kept driving. Three more hours of driving at highway speeds and it only came back on once. I then took it into autozone and the code reader told me I had a Cylinder 3 Misfire. The guy told me to change my spark plugs and I would be fine. It was time for a spark plug change anyhow so I drove home and did it. After I changed the spark plugs the car did not start at all. It would cough and sputter and try to start but not actually start. Changed the spark plug wires and then the car stopped even coughing and sputtering. It just didn't start.
I then noticed that my fuel line that feeds directly into the engine was rotten right next to the engine and if I pushed it in I could get the car to try to start. (Try and fail, but at least try.) The fuel line is a molded piece of rubber that flares at each end. It was one of the flares that was rotten and didn't seem to be sealing anymore. The hose is 7 mm inner diameter in the middle and about half an inch on the ends. I took some 3/8 in fuel line and used it to cover over one of the flares. The car tries to start now but wont. 3 of the four cylinders crank. I don't understand how I could break my car on such a simple repair job.
