Elantra XD (2001-06) :: Misfire - CEL Flashing When Give A Lot Of Gas Like Taking Off From A Stop Light
Dec 14, 2014
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

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???

I bought my car from the dealership new in 2006. 2005 Elantra GLS 5 Door. I did not know that there was an alarm nor has it ever gone off before in the 7 years that I've owed it. Three years ago I had an autostart put in. No longer have original remotes.
Today I used my remote to unlock my car doors. When I opened the back door an alarm started to go off on my car and the headlights were flashing (no horn honking). I tried using the key to unlock in the door and in the ignition to make the alarm stop.
I unhooked the battery and as soon as I hook it back up the alarm continues. Called the autostart company and they told me the autostart didn't come with an alarm. I called the dealership and they said if it was a factory alarm that it would honk and not make alarm noises.
Found my original window sticker says "keyless remote entry w/ alarm" .. Other than having my car towed to the dealership, how can I make this alarm stop?

O.K. first of all I had an issue with the Odometer pointer being jumpy. Sometimes it wouldn't move. Now I replaced the input sensor at first and did not fix the problem. I replaced the output sensor and fixed it. "BUT", Now, I have a problem with the transmission shifting. I get an engine light while driving and the 2nd gear seems to take its time shifting and when it does it make the left side drive shaft kick in hard and spends my wheel to a screeching effect. Plus a thump on the transmission. I rechecked the sensor for connection and reinstalled. Drove the car still have the same issue?

Today I was driving and all of a sudden the car started to seem like it wasnt responding well when giving the gas. then the check engine light came on flashing. I pulled over to check in my manual and it says there is a malfunction with the CAT, it started to smell like eggs. now i remember reading once that the smell of eggs is a burnt cat, is this the problem or could it be only the sensor ? How much a new one goes for ? how about the cat, how much does that go for ? if it is my cat how does putting in a high flow cat sound? good or bad ?

2001 01 1.8t... Hoping this isn't a bad ABS module. When I bought the car, I was told it was a bad wheel sensor in the drivers side. But, the funny part about this is its not on all the time, sometimes it doesn't even come on and the dash is normal.

I have a 2006 6.0. It's hard to put into to drive and for you to get it moving you have to just about floor it. The tow haul light is flashing but my bullydog won't pull the codes. It stops moving after like 30 to 40 ft after you got it moving and acts like it's in natural. If you turn it off and back on it sometimes will move another 30 to 40 ft sometimes. It also sometimes if you put it in reverse won't let you give it gas. Like you can push the pedal but the rpms won't climb for this reason I'm thinking something to with a solenoid or fuse or something along those lines and also because if you restart it will move again. I don't know much about transmission. I'm taking it to a shop tomorrow for them to try and read the codes. If they say the transmission is toast i already located another one 2 hours away to swap in which I'll do myself to avoid the high cost of the shop which also I'll look to yall for guidance. I drained some of the transmission fluid and didn't see any metal flakes. Should I pull the pan as well and look if nothing is coming out in the trans fluid ?

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.

I have a new problem that I only discovered a few days ago. As I come to a stop at a traffic light, turning out of somewhere or whatever if I give the car a little more gas than normal not that I punch it or anything from a stop the car bogs down and bangs a little rough like I was rear ended. The car is in drive when it happens. Its just fine any other time. I was told it could be as simple as a bad tps or as bad as a defective torque converter or tranny. Its a 2005 gls hatchback with the 1.8L. also, the engine has been running a little rough recently too if that could have anything to do with it. No warning lights are on either.

This issue has only happened twice to me.
I go out to start the car, it cranks and cranks and cranks. I stop turning the key. I then try again and it hesitates to starts. I give it a little gas and it starts. When it does this, the car begins running very rough and idling rough. When I give it a little gas while it's parked, the check engine light begins flashing at me.
I turned the car off and came back to it the next morning (maybe 10 hours apart). It started right up no problem, no CEL either.

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.

2004 Elantra AT ... 6 months ago top of the radiator cracked caused it to overheat and blow the head gasket and warp the head. Repaired that and compression is fine now. It ran great for 4 months but now it randomly stalls. at or near idle. Seems to do it more at operating temp rather then cold. Occasionally the check engine light will pop on and the code reads (random misfire). It acts just like it has been shut off. But immediately restarts.

The stop lights and the tail light of my Elantra GT 2001 (automatic transmission)won't shut off, unless the fuse is removed from its place. Is this something easy to fix? I imagine it can only be some kind of switch on the break pedal/clutch.

New post for a better problem. It was a hot day today in vegas, but my santa fe was running at normal temp (I double checked with my analyzer), running great. When I got home I turned the key off and took it out of the ignition, all the electrics went out (lights, gauges, etc.) yet the car was still running. It took about 5 seconds or so for it to wind down and stop.
2001 Santa Fe, 2.7ltr, 120,000 mi., 2 wheel drive, great shape, no codes.

When @ a light or stop sign the car vibrates excessively to the point it makes my daughter sick. I do feel it vibrating but it doesn't bother me but something is definitely wrong. There are no engine lights on, I can hear the top end tapping and clattering, I did check the valve clearances which seem to be barely within specs. She says it vibrates worse when the tank is full. She also said when the tank is full the front end shakes driving down the road. I'm kinda wondering the front end shaking with a full tank might be the rear struts.

My 2002 Hyundai elantra gls has had a problem with losing power when accelerating from a light. only after filling up gas and has done it only three times. I cleaned throttle body and noticed the mass air flow sensor is missing and wiring. I went to AutoZone and no check engine light for mass air flow sensor and that I have one for fuel pressure sensor in tank. I don't wanna throw money in to the mass air flow sensor if my problem is the fuel tank pressure sensor.

Alright so I've had this car for about six months now and the clutch was supposedly replaced by the dealer I got it at. The clutch usually grabs about half way up but sometimes it's higher. I replaced the master cylinder because it blew out, when changing my I take I noticed the slave was starting to leak so I replaced that about three weeks ago. Ever since then, the clutch seems to grab differently and seems to be taking longer to engage.
Now, I did the "slave mod" on the old one AND the new one so it's not that. Do you guys think the new slave is bad? I have high temp dot 3 in there (I try to only use the best fluids for my cars). It just doesn't seem to grab as hard as she used to. Like it takes a bit longer to engage. The clutch (should) only have 15k miles on it. The clutch parts are under warranty but I'd still have to pay for labor since it's a wear part. I'd like to avoid replacing it if it's that new u less it's definitely going.

The car died on me the other day at a stoplight but started up again (It resisted for a sec but then caught). Now it's taking a bit to start and sounds very faint when it finally catches and the turn over is slow. I'm no mechanic but I can replace parts. I'm just wondering if it's the fuel pump or injectors, maybe low fuel pressure. I haven't had a chance to do anything to it. Where to start?

99 F250 7.3 everyday worker, just recently my tranny slipped as I was taking off from a light, I thought hmm that's odd! Pulled away from the next light , it did not slip! Later in the day did it again, so I ran by the transmission shop to have a service done, to my surprise I was told service would not work, and a rebuild was going to be 3200-4k. truck has been used lightly for the last week or so, slips sometimes and not others. I still believe I need to have it serviced? can I do this myself ( I haven't a clue)....

Driving the other night I ran drove over a pot hole going about forty pulled up to the stop light and my car starts to make funny noises, barley got the car moving again but managed to get home. I hooked my computer up to it and it says misfire at cylinder 2 and 4.

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?
