Golf V R32 :: Check Engine Light Blinking - Car Running Rough
Our R32 has 2428 miles- and today the check engine light came on and it started to run pretty rough, babied it home and the the light was blinking when I turned into the driveway.. I know that booklet 3.2 in the owners manual is diagnosing catalytic converter issues...I have always used super unleaded, it hasn't even reached the halfway point of the first service.

So last Thursday I started my car up in the blistering cold and it ran fine for about a minute and started to misfire so I shut it off. It hasn't ran since. When that happened the check engine light was blinking because of the misfire. I didn't have a code reader at the time to read it. now that I got a code reader the damn thing isn't throwing any codes. it spits and sputters sometimes. I've had no previous problems with the car. Thinking It might be a weak fuel pump or bad coils and in not sure how to test them.

I just posted how happy I have been with my 2004 GTI 1.8t, then something strange happened. I was coming up to a light at night, turned on my turn signal and hit the brakes. The engine stopped abruptly and then began running fine without a restart. It was only for a split second. The lights went out, car died and began to run again very quickly. I noticed later that the clock had changed to the wrong time. I have noticed that lately at night the headlights dim slightly when I brake. That's the only clue. New battery, Alternator checks out fine.

The check engine light came on again after coming on about a week ago and then shutting of by itself. Everything seems to run normal with the car so I don't know if I should ignore the light and just keep driving or what. What would you do? My car is a 2011 Ford Taurus.

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.

I own a 2012 Black Golf TDI, had it for about 3 months now and loving it.
Anyways, so I'm aware that when the car shuts off, the fan is still running until it finally cuts off. Last night I got home and when I exited the car, it was blowing pretty loud like the car was still on. I didn't think much of it and just went in the house for a few minutes. It was bugging me that it was louder than usual so I went out to pop the hood to see what's going on. Found nothing so I went ahead and started it up again and shut it off. The fan noise went away after that and shut off properly.
Is there any harm that the fan was blowing louder than usual? I know it's a little vague but just wanted to get an idea because this was the first time it happened.
Chrysler :: 1989 - Check Engine Light Came On - Running Roughly
Recently, my car has started to run rough with the check engine light on. I cycled the key 3 times and checked for codes. I got a code for the MAP sensor and a code for the 02 sensor. I got no codes for a misfire, so I guess the plugs and wires are okay. I bought a new MOPAR Map sensor and installed it. It still runs the same and the check engine light is still on.. My question is, is it necessary to disconnect the negative on the battery when doing this and for how long? I did disconnect it for about 2 minutes and it still was the same.

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.

View 5 RepliesPrius (2004-09) :: 2007 Won't Start / Check Engine Light On And Fan Is Running
2007 Prius. It is a very cold day (5 F) and it won't start. I pushed the button as usual- first time the keys were still in the house and it did give the indication. Then the panel lit up normally but wouldn't go into reverse. Then I tried shutting down, had to hit the button a few times, and now all I get is the check engine light and a fan is running somewhere. The other thing to note is there was a beeping when I opened the door when I first got in and was running around getting the keys etc.
I have two little ones who don't like me to spend time on the computer, so I did a quick look around here and saw that the red triangle symbol with the exclamation point means the 12 volt battery is low. I get that warning on and off for probably at least a year... couldn't find any information on it in the manual so I was just ignoring it. Does this mean my 12 volt is completely dead? Is that the hybrid battery or the regular battery like in a regular car?

Ford F-150 (2009-2014) :: Truck Running Bad And Check Engine Light Came On
After about 5 miles from my normal place to purchase fuel, My truck bagan to run bad and the check engine light kicked on. Mileage dropped to about 8 MPG. This morning, the truck would not start and after 2 can's of dry gas, I was able to start it (barely).
I stopped at the place where I purchased fuel and at least they admitted that they has to shut down yesterday, stating they received a bad batch of fuel from their source.
Now the fun begins...How do I get the "bad gas" out of my truck?. I now have about 1/4th of a tank. I tried to run a line to siphon the gas and I can not get a line far enough into the tank.
Prius V :: 2012 - Check Engine Light On
I have a 2012 with 2500 miles. Everything feels fine, but the check engine light came on today. It is a holiday weekend and tomorrow, Sunday we are supposed to hit the road for a 500 mile trip. I checked the gas cap since I filled 60 miles ago and this forum indicated that can be the source of the light. Sure enough it was on but not tightened. The light is still on. Dare I drive?
View 2 RepliesWindstar :: 2002 - Car Running With Blinking Check-engine Light / Code P0306
So I had a serious runability problem back in 2012 with code P0302 (misfire in cylinder 2) and the car was barely running. I changed the spark plugs, which didn't fix the issues. Then changed the coil, which fixed it. URL...But I was a little lazy back in September 2012, the old spark plug wires looked like they were still in great shape, so I left the old wires on. I think they were the original factory wires, they had the numbers of each cylinder printed on the side. Very nice wires!
Fast-forward to the present. Car starts running poorly with a blinking check-engine light. Not good! I check the code and it is P0306, misfire in cylinder 6. So my first thought was: OK, probably time to change the spark plug wires!I changed the spark plug wires. I purchased AutoLite Professional Series wires at Advance Auto Parts, part 97047. URL...Sure enough, the number 6 wire looked like it had a little corrosion inside the end that connects to the spark plug wire. It looked like I was on the right track! Changed the spark plug wires, and ran it. It still sounded like it might be missing on one cylinder. Just a quiet ch-ch-ch-ch-ch-ch at idle. I took it for a test drive. It ran OK at low RPM's, but had no power. When I tested some hard acceleration, sure enough the check engine light came back on. Tested the code and it was P0306 again. Conclusion: not fixed yet.
OK, maybe the spark plug wire was the problem, just the plug got fouled because the wire was bad. I purchased a replacement spark plug for that cylinder only. AutoLite Double Platinum as recommended elsewhere in this forum. Removed the old plug. I'm no expert, but the old plug looked fine to me. Installed the new plug. Tested it again. Still sounded like missing at idle ch-ch-ch-ch-ch. Test drive, OK with low RPM, no power. Tried hard acceleration, got the blinking CEL again. Conclusion: still not fixed - darn it!
Now remember, I just changed the coil back in September 2012. I had replaced it with a coil from AutoZone. The first coil had lasted ten years. So it couldn't be the coil again this soon, right? But... just to be sure, I went ahead and changed the coil again. I called AutoZone and happily it was still under warranty. The previous coil I had purchased came with a 24-month warranty, and I was on month 23 !!! Sweet!AutoZone also told me if I did a warranty replacement of the coil, the new one would come with a lifetime warranty instead.The part number of the coil at AutoZone was part C1312, Duralast Ignition Coil.
Before installing the new coil, I put a little Dielectric grease around the top inside of each connector on the new coil (7 total, six spark plug wires plus the electrical connector). I think this was recommended in my Haynes or Chilton manuals.I am a tall skinny guy with long skinny arms. So I was able to replace the coil without removing the cowl. Last time I had to remove the cowl (to do the intake manifold isolator bolt repair) the cowl had cracked, also some of the clips holding it down broke. So I didn't want to remove the cowl unless necessary. It turns out with my long skinny arms I can lay up over the motor and reach back around both sides of the intake manifold to reach the coil. It is a reach, but it was possible for me to do the job that way.
I removed the three bolts holding the old coil in place. Then I was able to slide the new coil back in there, around the driver's side of the intake manifold. I transferred over the spark plug wires one by one from old to new (as recommended by another poster) so I wouldn't get confused which was which. It worked well to transfer the rear three first. That hold the new coil near the correct location, and gave me more slack to move the old coil further out of the way.Next step was to remove the wire connector from the rear of the coil pack. It didn't want to release. I looked at the old part (from 2012!!!) and there was a little plastic nub back there to lock the connector in place. It looked like there was room to work in a small screwdriver back there to release the lock. So I wiggled a short flat-head screwdriver in back there (with a wide head) and it released. Then I was able to easily remove the connector.
Then I had more slack to move the old coil further out of the way, toward the drivers side and front of the vehicle. And then transferred the last three spark plug wires to the new coil.Then to secure the new coil in place, I carefully installed one bolt by hand, leaving it loose to allow for final adjustments of position. Installed the second and third bolts loosely. Tightened the three bolts finger tight using a short (3") extension and 7mm socket (1/4" drive). Then snugged them very gently using my small 1/4" rachet. The small 1/4" rachet was a perfect fit using the 3" inch extension and the small 7mm socket. Remember you just want the bolts snug, do not over-tighten them.
When I went back to AutoZone to process the warranty return, they had to do some fancy work with their computer to get me the lifetime warranty on the new coil. By default it would just assume the rest of the original coil warranty from 2012 - which was just about to expire. So they made it right for me - but only because I specifically asked about it. By default, the guy had already rung it up their "normal" way, which would not have extended the warranty for me.Another thing that was strange was back in September 2012 when I replaced the original coil, it had worked well for ten years or so! Also, the bottom of it was clearly cracked, so it was easy to see that it had deteriorated and needed to be replaced.
Elantra MD (2010-15) :: Running Rough / Check Engine Light Came On And Misfire Code
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?
