Passat (B5) :: 1998 - Check Engine Light On And Car Started Missing
May 8, 2006
Lets start at the beginning. About two weeks ago my girlfriend got a check engine light and the car started missing( 98 Passat 1.8T, 5 speed). Checked obvious things like fuel delivery-good. Pulled coil packs and had no spark on #2 cyl. Investigated more and found one of the pins on the ign. control module was shorted. Felt pretty sure that was the problem since everything else checked out. Ordered a Huco installed it and that fixed the problem except the car seemed slow reprogramming to the new part. I disconnected the battery to clear the memory and that seemed to do the trick.
About 2 weeks later my GF is coming home and fortunately it died in front of the apartment. Checked everything again. Getting fuel, no wires shorted on ign. or fuel harness plus they all get power just no signal when checking with an LED tester. Ign. module was good also. Checked speed sensor for resistance per the book it was good. Tried a new Camshaft Pos. Sensor hoping that was the problem, no luck. I believe it must be the computer. I'm trying to get one from a salvage yard. I don't know if the old computer can be reprogrammed or not. Also was wondering if the dealer(where I really do not want to go) can test the computer somehow and tell me if it is bad or not(don't know if I would trust them anyway), just wanted to include that option.

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.

During a hard acceleration to get on the freeway, the car "missed" and the check engine light came on. The shop said it was the fuel pump and replaced it. When I picked it up, they told me that I may need a new battery soon because the last start they did was hard. It worked well for me, but that day it was hard to start, but it did not seem like the battery. The shop checked the electrical system and all was good. They said the new fuel pump was faulty and replaced it. Since then, when it is over 70 degrees out (South Texas), and it is a hot start (I just drove it a while, turned it off, and try to restart within 30 minutes), it is hard to start. Could this be another faulty fuel pump? Is this some other problem? Could the shop have damaged something during the fuel pump replacement?

I bought 04 Lariat (5.4 3v around 100k miles, Roush Off Road side exit exhaust, DWV intake mod, SCT 3015 tuner).
The truck has had a miss on and off for around a month I've changed plugs and tested all the coils. Which cured the problem for around a week, the FPDM had some white stuff on back and soft spot but not ate through. The only Check Engine Lights have been bank 1 to lean (which went away as soon as it came. But yesterday and today I've got bank 2 to lean.
Below is a quick data log pull... The misses is about ready to ship her out if she don't straighten up..

While I am driving the car it will start to die and skip. Happens randomly. Today I was driving up a small hill and it went quits on me started lurching with check engine light coming on and off. The car will turn over and start, but only for a few seconds before dying again.
Seems to happen when the car is running for a while. Also the ABS light flashes on then off randomly while driving sometimes although It hasn't been an issue. Will be checking tomorrow to see if it starts.

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.

The check engine light is blinking on my 98 Mazda Protege. I'd like to purchase one of those little hand held computers so that I can diagnose the problem myself. Should I leave it up to the professionals?

Out of nowhere my check engine light came on bought some oil thought it was low, and i just recently got an oil change. Checked my sparks and it was okay. Couple hours later my car began over heating With engine light still on, and my temperature gauges increased knew something was wrong, filled it with anti freeze to cool it down, continued driving and the issue continued. Bought me a knew sensor, I noticed it worked but did not fix the issue, my car continues to over heat, couple days later without driving it, this morning on my way to work it was really cold so my car did not overheat, but my check engine light began blinking and my vehicle began rattling from my house all the way to work, for about 9 miles. Whats wrong with it? Is it safe to drive back home after work.??

I have a 1998 Passat v6 triptronic I recently had a lot of work done on the car including a new throttle body I have noticed since I got it back from the mechanic after a short drive it starts to miss and you can actually feel the motor shaking around through the drivers seat, I had a couple of passengers in my car (back seat) and they could feel it too, seems to be fine when I first start to drive it but after around 5 minutes it starts shaking, I also noticed today when I got home I opened the bonnet and the motor seemed hot as did all of the parts around the motor including the water in the top up tank. friends keep telling me it could be my spark plug leads but I am more inclined to think it may be a coil, when I check the temperature gauge it is on half way and this seems to be normal for my car so it's not showing that the motor is getting hot.

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.

My mother in-law has a 94 Chrysler LHS, 3.5 V6, auto, 66k. Yesterday she was driving home and said the check engine light was on. I went to check it out and the light was not on. The light come on when the key is turned on but goes out when it is started. This is not an OBD-2 car it has a little blue plug and i do not have a code reader for it. Took it to auto zone and they do not have a code reader for this car. Auto Zone and Pep Boys both told me that if the light is off there will not be a code. Further checking on the internet I found out you can get a two digit code by turning the key on and off and count the flashing check engine light. It worked I got code 12 and 51. 51 means lean O2 sensor. If this is true that why does the CEL not stay on. How can I test the O2 sensors?

I have a 1998 Toyota Rav 4 with apporximately 140,000 miles. When I fill the gas tank the check engine light comes on, the engine runs rough (like a misfire). Diagnostic code comes back a "lean mixture,bank 1". When the tank reaches approximately 3/4 of a tank the light goes out and the engine runs smooth and fine. Then, when the tank reaches just belwo hal a tank the light once again comes on and starts running rough again. Have drained the tank, used dry gas, Startron to counter the ethonal etc. Nothing seems to work.

About two weeks ago, while driving on a hot, humid summer night, the check engine light in my 1998 Toyota Corolla came on. The following day, I took it into my mechanic, who plugged it in and came up with the code P0441 (Purge flow fault). He told me it was likely related to the fuel vapor canister, though I see this can also have to do with vacuum lines for the purge valve and canister or a bad purge valve itself. My gas cap was, and had been, tight, so it wasn't something as simple as that.
Reluctant to deal with this immediately, I went back to driving it, and lo and behold - the light went off after several days! Unfortunately, the light came BACK ON after several more. And most recently (a few days after coming on again), the light has now gone off!
Both times the light has gone off, the weather has been rather wet, but otherwise, there doesn't seem to be a clear pattern. What this on again off again pattern might say about the problem?

I have a 1998 chevy 3500 2wd pickup with a 454 engine. The check engine light is on. I have had the codes read and they were for a MAF and MAP sensors. I have replaced both. The check engine light is still on saying that I have a bad MAF sensor. I replaced it again. The check engine light still is on. What else should I look at to fix this problem??

The other day my 2000 Echo started missing, she would run fine until after about 5 mins. After that, it would run like it was only running on two or 3 cylinders so I took her to Auto Zone for a code check--it came back with p1315,p0141 & p0304. On the way home it really got bad! She started dying on me. Just like u turned the key off. Before coming to a complete rest I turned the key all the way off and back on and she ran for 30 seconds or so - You would have to turn her all the way off--back 2 clicks--one click back would not work and this is the way I got her back home--about 7 miles turning her on and off. I wish now I had not hooked her up to there code checker because I think it burnt something out.

I've got a problem with a 2000 Impreza 2.5RS 5spd. It started with the check engine light coming on. A trip to Auto zone revealed that the O2 sensor was the problem. But on the way home, the light came on again and started flashing. All the while the car started acting like it had a misfire. It idles really rough and the exhaust smells like it's running really rich. I've replaced the plugs and wires, and all corners of the ignition coil check out properly as well. Can the O2 sensor cause a misfire in one or more of the cylinders? Or is something else that I should be interrogating as the cause?

My '98 4.0 has 213k on it and the other day I started the engine and the jeep started shaking like crazy. Eventually the engine quit and refused to turn over so I looked under the hood and quickly discovered the problem, a deteriorated rubber elbow on the left manifold. The elbow connects to a threaded breather type valve in the manifold and has a thin piece of black plastic routing to the purge solenoid next to the left fender/air box.
When I removed the rubber elbow from the manifold the engine eventually turned over and idled fine, I then headed to autozone and found replacements of the same diameter, I cut them down a bit to match the length of the originals. Since its been a while I changed the plugs and wires, coil pack along with cap and rotor while I was at it. I replaced one plug and wire at a time to ensure I didn't mix things up, same goes for the cap. Now the jeep seems to take a few more seconds to get started but once it does it idles fine.
Now when I hit the gas hard the jeep will hesitate and then backfire. If I'm smooth on the gas the jeep drives good, whether city or highway. When coming to a stop the jeep will sometimes buck slightly like it wants to cut but doesn't. The backfire sounds like its coming from the air box and oddly enough, my aftermarket radio no longer plays in the accessory position, probably a separate issue. So far there's been no check engine light.
I really need to keep this jeep for a few more months and I would hate to put big money into at this stage.
