Accent LC (2000-05) :: Stalling And Idle Roughly Once Warmed Up - Random Misfire
I'm having continued issues with my mom's POS 2005 Hyundai Accent. It usually runs great cold, but once it's warmed up, it will stall out while driving. This almost always happens when accelerating from a stop. After it stalls, you have to let it set for 30 seconds to a minutes before it will start again. It will also sometimes idle roughly.
I've changed out the TPS and the MAP sensor, the battery, the CPS, the fuel pump, and the spark plugs. I did find that the radiator bypass hose was leaking on to the wiring for the O2 sensor. I fixed that, and the wires appear to be fine. I've sprayed throttle cleaner around the intake and can't find a leak. I scanned the ODB codes and I'm getting a Random misfire, misfire on cylinders 1, 2, 3, and 4, the Throttle Position Sensor and the MAP sensor, both of which have been replaced.
Tonight during my troubleshooting I was trying the wiggle test on the various connectors and got zapped when I was wiggling the coil pack connectors. Is that normal? I'm starting to suspect a wiring or electrical issue, but I'm not sure how to troubleshoot that.

Driving down the highway today, my car just all of a sudden quit. I had it towed home, and checked the spark and fuel pump. It turns over fine, there's plenty of spark, and the fuel pump works great, but I don't think fuel is getting all the way to the engine. Could the fuel line be blocked or something? Maybe the injectors?
View 3 RepliesAccent LC (2000-05) :: Steering Wheel Shakes Quite A Bit At Highway Speeds 70 MPH
My accent just crossed 180K mark. From last year the steering wheel shakes quite a bit at highway speeds ,say 70MPH. It's especially bad when I accelerates . Took the car to a shop, they told me two things, the CV axle of passenger side needs replacement, and the wheel hub bearings are bad(both front wheels). They quoted me $200 for replacing the cv axle, and $400 for replacing both front wheel bearings. Since I don't even think the car worth $600 right now(given high mileage), I told them I'll just do the axle(I know how to do it myself but don't have the time, plus it won't be that much cheaper DIY anyway). They said fine, but if you don't replace the bearings you may have the wheel fly off one day and that's dangerous.
They replaced the axle, and the car drives a lot better now. There's still a little bit of shaking at high speed but 75% of that shake has gone away. My question is, does the worn out bearing causes car to tremble at high speed? I heard other people told me there should be a grinding or loud hawling sound if the bearings are bad, but I don't hear that. I searched the internet and some people say, to determine if the hub bearings are bad, just drive it for 10 minutes then feel the hub. If it's barely warm, the bearings are good. If it's warm to hot, then the bearings are bad. I felt it and it's warm, but not too hot to touch. I tried the rear wheels and those are barely warm indeed.
So from this method it seems the front wheel hub bearings are indeed bad. I wonder how long I can keep driving this without endanger myself. $400 is not cheap for this car and I don't have a machine to press in the bearings myself. I can disassemble the rotor and hub that's not a big deal, but I don't know how to get the old bearing out and the new bearing in. Is there a machine shop that just do the pressing? Or, is there any shop selling the hub assembly with bearing already in place? this way I just remove the old hub assembly and replace it with the new assembly, a lot easier. I searched the internet but can only find pre-assembled hub w/ bearing for the rear wheel of this car. I need the front ones.
Accent MC (2006-11) :: Idle Speed Will Increase To Around 1100 RPMs
I noticed on 5 different occasions so far this year that my idle speed will increase to around 1100 rpms when sitting at idle for more than a few min. Last summer it did it while running a/c, and today it did it with cold weather. The rpms are usually at 550, what happens is the pcm will decide to increase idle speed for no reason at all. Start driving it, and the next time at idle it will stop doing it, a couple times it went down to 550rpms, then went back up to 1100rpms. I recently changed the spark plugs, the air filter is clean, and runs good. I have a code scanner, no pending codes. I have 53k miles. I wonder what could cause this?

View 1 RepliesFord - Explorer :: 2000 - Consistent Knocking Noise Increases As Engine Speed Increase
I'm looking at a dirt cheap Explorer 4.0, has been sitting for 2 years. Runs nice, with a double "knock" noise but quieter than a rod knock. Idles smooth at 600 rpm, "knock" is consistent, but increases as engine increases speed. Has 2 year old oil, and 2 year old gas. Would a tune up support it, and revitalize it, or is the engine almost dead. Still drives, didn't push it to hard. Interior is 9/10, exterior is 10/10. I have him down to 600. 4x4 works, and feels good.
View 6 RepliesAccent MC (2006-11) :: 2010 - Random Crank And No Start
I have been having this issue randomly, sometimes it won't occur for days and other times it happens in a short period. I will place my key in the ignition, and everything will chime correctly, and when I turn over my engine, it sounds like the engine catches then it just stalls. The things I have changed so far is,
battery ( needed to be changed anyways)
spark plugs ( was set to be changed)
air filter
cabin air filter ( no relevant but still...)
oil
At first I thought it could be bad gas, since I fill up sometimes at safeways etc, but in my tank right now is 91 octane shell, I thought it could be spark plugs since I was a little over due so I changed them, and the issue never popped up for 2 more weeks, then it came back.
if I use my car starter it seems to start better, but it is maybe 1 out of 10 times it will just crank continuously without catching or anything.
I can hear my fuel pump whirl when the key is turned but not started, I checked the oil today and it is full and a light color, maybe 500 km on this oil change.
Here is the youtube issue of what is happening... [URL] ......
I rather cover most of my bases without having to bring it in for servicing.
Accent MC (2006-11) :: Random / Multiple Cylinder Misfire Detected
I guess misfires are a rite of passage for these vehicles. I purchased it only a week ago. Welcome to Hyundai...
The car has 53k kms. It's throwing P0300 and P030X on all cylinders. There was one instance of P0128. The engine runs smoothly and doesn't seem to down on power, although I have nothing to compare it to. The only performance issue is that it acts as if there is a rev limiter at 6k rpm. It sputters and stops pulling above 6k. Strangely, it doesn't throw the codes under load. The light flashes while it's running steady-state.
I pulled the plugs and they appeared to be in excellent condition with no erosion of the electrodes. The ash is slightly more white than I would expect, making me wonder about it being excessively lean. I called the dealer. They told me that coils are problematic. Replacing the coils made no difference.
That lead me here. I found the thread "Check engine light flashes then stays solid," which referenced the ECM update.
Interestingly, of the codes mentioned on the TSB, the car is having all but the last two.
- P0300: Random/Multiple Cylinder Misfire Detected.
- P0301: Cylinder 1 - Misfire Detected.
- P0302: Cylinder 2 - Misfire Detected.
- P0303: Cylinder 3 - Misfire Detected.
- P0304: Cylinder 4 - Misfire Detected.
- P0128: Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature).
- P0328: Knock Sensor 1 Circuit High Input.
- P0461: Fuel Level Sensor A Circuit Range/Performance.
Accent MC (2006-11) :: 2007 GLS - Random / Multiple Misfire And Code P0300
I have a 2007 Hyundai Accent GLS. I just got it from a used car dealership (local) and it runs perfectly. It had a misfire code when i first got it, for all cylinders plus the p0300. It went away when i started the engine again, and didnt come back til a month later (Now). now it wont go away.
I went to advance auto and had them use their OBD2 reader for a trouble code and i got p0300, p0301, p0303, p0304. No other codes present.
I am not feeling anything bad, and from what I am told, a misfire feels like a hard shift. This is of course after getting the plugs and wires changes as well as an oil change. Standard preventative maintenance.
The mechanic used OEM parts got from local parts shop. i think the OEM plugs are the copper ones. I would have preferred iridium as they arent that much more expensive but I don't want to pay for another plug change.
The only symptoms I can think of, is that according to google, I should get around 380 miles to a full tank (11.9 capacity, 32 mpg city). I am only getting 280 from full tank to gas light.
I have also gone through a lot of oil. I checked the dipstick and it was below the low line, so i bought a quart of high mileage oil (same exact brand and type of oil that i gave to the mechanic to use) and it went to just above the full line. This was at around 1500 miles after oil change.
After visiting multiple sites about misfires, i found a few things that caught my attention. One is a site called auto service professional, which talks about the OCV for the MC accent. A lot of sites also recommend gaping the plugs at .035.
Accent MC (2006-11) :: 2008 - Car Started Jumping And Being Sluggish / Random Misfire Codes
I have a 2008 Accent Hatchback with 130k+ miles. I got a pretty good deal on it from a fellow who maintained pretty good service and had installed an aftermarket air intake (well, he removed the stock one and put a small, roughly 4" diameter, filter that is open to engine compartment) and all looked pretty good.
At the first fueling, I noticed issue - I had to rev motor for about 30-45 seconds to get it to stay started. Figuring it was an evap issue, I replaced purge valve and gas cap (cap was obviously loose). This did not correct the problem. I did not worry about it to much because with that exception, the car drove wonderfully back and forth to work, etc.....until recently.
Car started "jumping" and being sluggish. Codes came back as random misfire. Plugs and wires are only a few months old. I wondered if it had something to do with fuel so I ordered filter and pump (figured i would replace both since I was going to be pulling top off tank anyways) - this is going to be my project for the day.
Here is the kicker though : I noticed in the past day or so that car has been okay on my short commute to work in the morning and back home in evening. When I went to store midday and was parked on HOT pavement, I had issues right away. Car is very temperamental as the temperature increases. My wife also noted that last night while driving about 15 minutes away that the engine wall was hot enough to be uncomfortable to the touch of her bare foot and issues were abundant.
Once I get to speed in 5th gear, I seem to be okay, no issues (yet). It is primarily during acceleration and mostly during low RPM (low for this car anyways which seems to run best at 2500+).
Accent RB (2012+) :: 2013 Moves Too Much On Highway
I got a 2013 Hyundai Accent se Hatchback, and just recently noticed that when I drive on the highway it kinda sways side to side too often. it happens on the highway, never when driving in the city. I'm guessing its the wind, but when I look around I don't even see trees moving or anything so I dont think the wind is that strong. we also have a 2009 Hyundai Elantra and it does the same thing every now and then, but it's very rare.
View 29 RepliesChevrolet - Montecarlo :: 2000 - Random Pop When Going Into Gear
I have a 2000 Chevy Monte Carlo SS with 120,XXX miles on it. For the past year, I've been hearing a very loud POP or KNOCK when I put the car in reverse from park. Here are the details that make it so vexing.
• It only happens first thing in the morning. For the rest of the day, there is no pop.
• It only happens in cooler weather (less than 50°.)
• The sound comes from different places each time. Sometimes it sounds like it's in my rear passenger wheel well. Sometimes from the front of the car. Sometimes from directly beneath the driver seat.
• Rarely, there will be times when I'm driving and I "goose" on the gas, there will be a light pop sound. (when in drive)
I've had all of the motor mounts replaced (per mechanics opinion) and the problem persisted. My mechanic suggested it might also be transmission mounts but he doesn't know without actually replacing them. From visual inspection, he didn't see anything suspicious. Since the car is probably near the end of its life, I didn't want to spend a lot (more) on something that might not even be the problem. I asked if it was safe to drive and he said yes. I have noticed that when I put my car in reverse each morning and hear the pop, it seems to jar the car rather violently.

View 10 RepliesGolf IV / Jetta IV :: 2000 VR6 Random Misfire In Cylinder 2 And 5
About a month ago my wife's 2000 Jetta with the VR6 engine in it started acting up and throwing codes. The codes it threw were for random misfire, misfire in cylinder 2, and misfire in cylinder 5. Starting out, we changed spark plugs, fuel filter, and made sure the injectors were clean.
The problem didn't go away so we water tested the coil and wires, but they passed that test. The wires were quite old and out of spec, while the coil was in-spec across all terminals, according to the vehicle service manual, so we installed some new OEM leads this weekend. While installing the leads we noticed a disconnected vacuum line and reconnected that as well.
The vehicle was driving great for two and a half days, then today while I was sitting at a stop light, it started missing really badly and felt like it was going to kill. It did this for about 5 seconds, then recovered and ran smooth for about 5 seconds, before getting really rough until I started driving when the light changed. It didn't do it when I drove it a few hours later at all. This episode didn't throw any codes either.
What could be causing this issue? Would the MAF cause the intermittent missing, or is it possible that the computer is going bad?
Ford - Crownvictoria :: 2000 - Random Misfires / Car Stalls
I have a 2000 crown vic, police interceptor..... 1st.. car started idling rough had the codes read gave misfire on 4 . So we had the boots and spark plugs replaced. Car ran fine for like 3 days then engine light came on again.. running rough... code read misfire in 8 so had the coils on 4 and 8 replaced... ran fine for all of 2 weeks. Again engine light came on... now showing a misfire on 7, but car runs fine..??. Anyways I noticed my battery gauge was marking a really low charge... but as soon as I would get on highway it would jump back up to normal...
It did this for a couple weeks, then I noticed the gauge was marking really low car was losing power... I have a new battery and alternator on car already. But still I had them tested; both tested fine... Then car kept stalling at stop signs ans red lights went ahead and exchanged alternator 4since its under warranty anyway. This cause the charge gauge was reading normal.. but car still kept dying... so replaced fuel filter... didn't replaced tps and mass air flow sensors too...but it still keeps dying on me. Now codes are coming up misfires on 4&8! Why does my car keep stalling and what would cause these random misfires especially when these coils have been replaced already???
