Nissan - Maxima :: 1998 - Check Engine Light Come On And Car Started Running Very Rough
1998 Nissan Maxima had a check engine light come on and started running very rough. I took it to get a code read and came up with P0320 and P0325. I'm not worried about the 0325 since that's a knock sensor. 0320 is a misfire on cylinder 2.
With the car idling, I pulled the power connector from coil pack 2 to see if it made a difference in the idle - nope. I did the same for the other cylinders, and each responded with a noticeable change in the idle, which was remedied when it was reconnected.
I moved the coil pack from #2 to #4 (swapping them) and the same problem existed - idle was rough and didn't make a difference when I pulled the power on 2, but it did on all other coil packs. So, it seems the coil pack ins't the problem since multiple packs don't seem to make 2 work, but they work on other 4 and 6.
I then pulled the spark plug from cylinder 2, it was very black and looked in bad shape. I replaced it. Still no love.
I then put a spare plug in the coil and was able to see spark as the engine ran, so it seems that the coil pack at 2 is getting juice.
So, I have gas (big odor when the car is running - seems super rich) I have spark. Still running very rough and the 0320 code remains.

Well it finally happened, a couple of weeks ago I was headed to an MX race and my check engine light came on and it started running rough. Long story short a piece of an exhaust valve broke off and went out through the head. Dealer has been great even though I was 300 miles from home and they did get me a rental(small POS SUV). Truck was supposed to be finished this week, but now they are saying the head gasket is on back order and they probably won't have one until the middle of April......... I can't be without my truck that long, but not much I can do. By the way truck is completely stock with just under 20K on it, and I have never had any issues with any of my Ford trucks or Ford diesels, even my old 6.0.
View 7 RepliesFord F-150 - 1997-2003 :: 2001 - Truck Started Jumping Real Bad And Almost Died / Oil On Sparkplugs
2001 F150, about 3 weeks ago I drove through standing water that was probably about 2 feet deep, as soon as I did that the truck started jumping real bad and almost died. I drove it around for a little while and it started to run better. After that it started to feel like it was misfiring badly. Between 40 -50 mph on the highway just giving it gas a little the jumping was pretty bad.
I decided to change out the plugs, thought maybe water got onto them and this was causing the issue, this was my first time changing the plugs in the truck and it was not nearly as bad as it could have been! I was able to do all of the plugs except number 7. The fuel injection line is right on top of that plug and I did not want to remove it!
After changing the 7 plugs the truck is running better now, I have not yet felt the jumping that was happening, my problem is that on the 4 plugs on the passenger side all 4 looked to be covered in oil. My question is does this mean my head gasket is blown and how long do I have before I am going to have to put alot of money into this truck to fix this issue?
Golf/GTI VI :: After Getting Fuel Car Started For Few Seconds / Running Real Rough Then Shut Off
So after taking my car to the stealership to get defective door seals fixed, I start driving home and I realize the front tire is flat. After changing to the awesome 17" spare, I decide to get gas. After filling the car up, it started for a few seconds running real rough and then shut off. I tried restarting it multiple times for about 10 minutes and the car kept turning over, but no start. I finally just shut it completely off for five minutes and it restarted, but is running roughly with the CEL light on and another green light, EPL, or something like that. I was able to drive home, but the check engine light is on still and runs like crap.....Back to the dealership in the morning. What this could be? I noticed lately sometimes when I push the gas hard it kinds of bogs down for a sec before accelerating. I had them check this and they said nothing looked wrong when they tested it. Fuel pump maybe?

Our Accent has just about 86k on it now, back in November it suddenly started running real jerky/rough, misfiring kinda thing. So I was able to drive it to my local repair shop and they found a bad coil pack on #3, so they replaced that and put in new plugs while they were doing it.
Just Saturday we were shopping about 20 miles from home and cranked it up to go home and started doing it again, pretty much identical symptoms, runs out normal at certain RPMs so I knew it was probably same thing...I was able to get it home and then took it in this morning and sure enough now #1 is shot. So they are replacing that. They want about 30$ more per coil then I can order them for myself online so I didn't want to scarf up the money for the other 2 that are still original.
Camry 2012+ :: Check Engine Light On When Started The Ignition
Was trying to change my reverse light on my 12 camry. I wanted to make sure the bulbs were working before I put everything back together. I put on the emergency brake put the car in the on position and put the car in reverse. Went to check the bulbs and nothing. Put the old bulbs in, nothing. Started the ignition and noticed that the the check engine light was on and also the P, R, N or D was not showing in the display. Let the car sit for a while and still the the same thing. What happened. All other lights work fine.
View 1 RepliesChevrolet - Sparkplugs :: Check Engine Light On 1998 Malibu LS
After filling the gas tank yesterday, as I was on my way to work, the check engine light came on. For the last couple of days the temperatures outside have reached 118 degrees. I have checked the oil and coolant and have resealed the gas cap as well, yet the light still remains. The research I have done leads me to believe the problem may be the catalytic converter, but I'm wondering if there is any further troubleshooting I can do without heading to a mechanic.

My mechanic tells me I need the intake manifold gasket replaced (check engine light on, engine surging, running very rough). How much damage can I do to the car by doing this repair myself and screwing it up? I've done lots of repairs on my car before -- brake pads, rotors, replace oil pan. I also have a copy of the manufacturer's shop manual.

Filled tank with 8 gallons of 91 octane to top off. One hour later noticed car running rough at idle then check engine light comes on. Could it be the coil pack? Car has been running very well until now, and this Gremlin appears. I don't think it's the gas.

Malibu :: Running Rough At Stop Lights - Check Engine Light Came On
I recently replaced the head gaskets in my 2003 Malibu. First time and all seems other than it runs rough at stop lights. The check engine came back on and so I had it read and there is an air flow issue. Is there anywhere that I can get a schematic for the vacum lines? I have all over and cannot seem to find a loose or broken one.

View 1 RepliesTouareg :: 2004 VW - Check Engine Light Is On / Running Rough At Low RPMs
I have a 2004 VW Touareg with 116K miles. Yesterday the check engine light came on and she is running very rough at low RPMs. The manual tells me that there is either a problem with the exahust manifold or an O2 sensor is bad. It feels as if she is struggling for air. When you start the vehicle the check engine light flashes then stays on in the cluster. What can I expect when I take it in to the dealership? Is there anything I can check before I take it in?
View 4 RepliesPassat (B5) :: 2003 - Check Engine Light Came On And Car Is Running Really Rough At Stops
I have an 03 Passat with about 70K miles on it. My daughter put rug in it this morning (about 7 gallons) and since then the check engine light came on and the car is running really rough at stops. While accelerating, it seems to be fine. It is also getting about 10 mpg less than normal. MIL codes: P0300, P0301, P0302, P0303, P0304, and P0171. He said the P03xx codes were related to misfirings on each cylinder. The P0171 is a bank 1 failure (?). What do those codes really mean and could they be related to bad gas? Sent her off in my TDI JSW so she's not out on the highway if the Passat decides it doesn't want to go anymore.

In the last month, my car has had an awful time starting on 2 different occasions. The first time it ran really rough for about 1 minute then was ok. The second time was the same but the engine light came on. Took it to an out of town dealer and he said it showed a misfire code but could never find anything else and all looked OK. Spark plugs?
View 4 RepliesFord F-150 - 1997-2003 :: 2002 - Running Rough And Check Engine Light On
My girlfriend has a 2002 F-150 with the 4.6 V8 and I was going to change the spark plugs for her. She said it started running rough and it threw a code and check engine light. She took it for a scan and they told her the number 5 plug was mis-firing. I'm fairly handy and bought a set of the recommended Motorcraft plugs from Rock Auto, AGSF32PM. It also matched the number in the owners manual so I thought I was pretty safe.
Funny thing, when I took the old ones out, they were AGSF22WM's instead. My thinking is they are a colder plug than the supposedly original equipment, but I don't think they've been changed before. They looked well used but the color was good. The truck has about 135K on it.
Long story short, and to get to the question(s), Would there be any reason the factory would have put a different plug in the engine than what is listed? Am I asking for trouble going with a hotter plug than what's been in there (pinging or timing retardation/loss of power)? Am I just overthinking the whole thing and need to put it back together and drive it?
Ford Excursion :: Running Rough And Check Engine Light Came On - P0353 And P0358 Codes
The X has been running great, well good enough, lately with no issues. I left work the other morning, and apparently the X didn't want to wake up that early. As soon as I started it up, the check engine light came on and it was running like crap. Had a bad hesitation all the way home. It feels like it is misfiring, but only under load. It doesn't do it if I brake torque it or Rev it up. Only while driving.
The codes I am getting are in the P035x family (typed that way for future searches). P0353 and P0358 are the codes I am getting (along with 4x4 codes for the vacuum solenoid...but that's the solution to other problems not relevant to this!). Being codes for the primary circuit, I popped the hood and checked out the connectors. Both connectors are fine, and tightly connected. I did notice however that cylinders 3 and 8 have other than OEM coil packs on them. These are the only 2 cylinders with those coil packs (they are white and the other 8 cylinders have black coils).
I don't want to just throw parts at it, and I'm not getting a hard miss fire code, just the 2 above. I might try to swap the coils with other cylinders tonight and see if the codes move to those cylinders. It has run like this a few times, but never set a code, and turning it off and back on has "fixed"this in the past.
And just for complete disclosure, while looking for where I saved a password, I found notes from August last year where I pulled codes, and these two codes were present then, with a cylinder 7 hard miss fire code. I replaced the c7 coil with motorcraft cleared the codes, and P0353 and P0358 went away and I haven't seen them since. The plugs are brand new and only have about 1000 miles on them (changed them in September when repairing the misfire and I don't drive it much).
