Passat (B6) :: 2006 - Cooling Fans Won't Shut Off
I have an 06 Passat 2.0T, and last night whenever I shut off the car, the cooling fan is constantly running. I had to unplug the battery so it wouldn't drain it, and about 5 hours later, I hooked it up and it stays off. I also noticed when turning on the air conditioning, the smaller fan doesnt kick on. I'm lost and don't know where to start. Could it be a thermal switch or the whole fan assembly

I've recently started popping up a random P2181 performance malfunction in cooling system.
It's so random and shows no signs of any other problems that I'm confused. Temp gets hot, stays exactly where it should be, 200. Never gets a tick hotter, or even close to above 200. Air works, heat works fine. No loss of power. It only seems to come on when I really put my foot down.
Passat (B6) :: Code P2181 - Cooling System Performance
Have an '07 2.0T w/92K on it. Check eng light came on over the weekend. Performance is fine etc. Went to AutoZone just to find the general area of the the trouble code since there's no one with a VAG Com nearby. The code is as the title indicates. For the last 5 months the temp gauge has been moving 1-2 ticks to the left (cooler) of the normal 200 degrees, then it will go back to 200 etc. It previously has always stayed on 200 once it warmed up. Does this sound like a thermostat?
If it is, I'm wondering if I could save some money while they were in there to go ahead and change the TB as well? From what I've researched the thermostat is in same area. I was planning on doing the TB at around 100-110k so while it would be earlier than planned I'd do it if it meant saving a bit from the combo work.

Passat (B5) :: Code P1296 Cooling System Malfunction / P1654 Check DTC Memory Of Control Panel ECU
I am getting to check engine codes and I can't figure out what is causing them, one is P1296 cooling system malfunction, the other is P1654 Check DTC Memory of control panel ECU, any clues as to why I'm getting these, I did have a bad thermostat i changed that and it's still on, I also used the new prestone antifreeze for all makes and models, cause I am about 200 miles away from a dealership for g12.
View 6 RepliesSubaru :: 2006 - Fixing CEL Code P0304?
2006 Subaru Forester X 2.5L AT non-turbo
I changed the oil and oil filter; replaced the air filter (Fram), and replaced the alternator and a/c belts. I also got a full tank of gas at Sam's Club, I was nearly empty. I've gotten gas plenty of times there, before.
Next day, the CEL comes on. It's a P0304 code. (Cruise control light is flashing, too.) Engine stumbles and runs rough when cold; idles fine when warm, runs OK, but not the same, when warm. CEL is steady, which is "not bad" but I can make it flash if I hit the accelerator while the engine is cold. Resetting the computer by disconnecting the hot battery terminal didn't work; CEL came on again two days later and symptoms remained.
I buy some MAF cleaner (CRC) and use it; MAF was pretty dirty on the upstream side, actually.
I'm going to change the plugs and wires (they need it, anyway) and I've ordered a new ignition coil, which I'll also switch out.
I've also ordered the gasket for the throttle body, which I'll take apart and clean once that comes in. Last step is to order replacement O2 sensors.
I'm 99% certain there's nothing wrong with the engine, in terms of rings, valves, pistons, etc. I think I'm covering all the bases in addressing this myself. I'm on a limited budget so I'm doing all the labor myself and ordering non-OEM parts on-line, after researching to make sure the parts have a good reputations, fit, etc. (Yes, that's all a big FU to Subaru service for being over-priced but besides being relatively poor I also enjoy doing this stuff.)
Accent LC (2000-05) :: After Every Fill Up CEL Code P0304 Came On
2004 Accent - auto. - 100K miles
CEL for code P0304. I thought I had it solved but now it comes on after every fuel fill-up. Its happened at least 5 times or more. I know what the code means (ign. misfire #4 cyl.).
I read and checked what affects the code but this one has me baffled. I thought at first it is the evap. canister but the car takes a fuel fill-up without any trouble and it is not hard to pump it all in and does not give me the code. If I put a bottle of STP gas treatment in the tank it clears the code after about 40 miles driving but it doesn't explain why it sets off the CEL on every fill-up. I also thought I may have sediment in the tank and the fill-up is stirring it up but I have filled her up and various capacities. Also, several weeks ago I got the CEL code P0441 for the purge control valve. I replaced it, cleared the CEL and it never came back on. Fuel filter has never been replaced because it is built into the fuel pump assembly.
Overall drivability and MPG's are not affected.
Sonata NF (2006-10) :: P0304 Code Popping Up
The code p0304 pop up last week, I have 50800 miles on my car, I unplug the spark plug and the ignition coil from the cylinder 4 and when i start the car I can there is a spark so the wire the spark plug and the ignition coil is good... I changed the fuel injecter with the one from cylinder 3 I cleared the code and it came back?

Have '01 SE. yesterday I got a misfire in cylinder 4 (code P0304) the service light blinked on and off 3 to 4 times than stayed solid. changed plugs and boots about 1 to 2 months ago, didn't change coils and they r not in the best shape but didn't have money to replace at time. So I replaced the coil for #4 and it still runs rough with code, plug has some ware but looks fine.
View 1 RepliesS-10 :: 98 Chevy ODB Error Code P0304 / Cylinder 4 Misfire
I left my chevy s-10 truck sitting over the christmas (23/24/25) and it was really cold outside and when i got back i started getting a P0304 (Cylinder 4 Misfire). I replaced the spark plugs and spark plug wires. May be the cold would cause this to happen? I think I've noticed the trucks fuels efficiency drop over the past month). May be the fuel injector(s)? Is the s-10 TBI or does it have fuel injectors for each cylinder?
View 8 RepliesCamry :: 2002 - P0304 Code / Misfire Occurring
We just bought a 2002 Camry with 72,000 miles 2 months ago. It now has 74,000 and while on vacation the CEL came on. I took it to a mechanic who got the code P-0304 off the computer. He swapped the number 4 ign. coil pack with the number 3 cylinder. The CEL light went off and I was able to drive the 300 miles home. The next day the CEL started again, but this time it's flashing. I changed the spark plug, it looked good, and still have the CEL on with the P-0304 code.
I've inspected the wiring to the number 4 ign. coil pack and it looks good. I'm thinking the next thing would be the fuel injector.
The car runs great, you'd never know by driving it that there is a misfire occurring. If it's not the wiring or fuel injector what should I check for next?
Golf IV / Jetta IV :: Code P0304 On Mk4 2.0 AEG - Misfire On Cylinder 4
2000 Jetta GL 2.0 AEG. I am receiving the P0304 which I have identified as Cylinder misfire #4. I read on some previous posts that I cannot be the distributor because if it was I would be receiving misfires on two cylinders. The spark plugs are OEM NGK and have been replaced recently.
View 2 RepliesPrius (2010-12) :: Code P0304 Misfire On Cylinder 4
Well, I have a big problem on prius 3, the problem is that it has a big and I mean a big body shake when I decelerate above 30 mph or slowly accelerate above 30 to 50-70 mph, when I fully accelerate, the body shake disappears. When the body shake occurs MIL comes blinking and DTC P0304 comes but not always, but the shake is only when the coolant is hot.
On the other hand, if the MIL is not on with the tester it can be seen that the cylinder 4 has misfire margin, only cylinder 4, every time. Now what I have done is to exchange the injectors, problem remains on cyl4.
-replaced the coils, problem remains on cyl4,
-clean the EGR, problem remains on cyl4,
-opened the engine to see the valves, cylinders, pistons, exchanged the ring set,problem remains on cyl 4,
Replaced the wheels, the problem is still there, now I want to replace the drive shafts.
Camry :: 2002 - Code P0304 Coming Up After Swapping Coils
Unfortunately I've neglected changing the spark plugs in a while. I've done so now with NGK iridiums. But still throwing the code. Thought it may be the ignition coil next. Swapped the current coils around to see if the code would change and no such luck. Erase the code and it still comes up as P0304.

View 2 RepliesFord - Escape :: 2001 - Misfire On Cylinder 4 / P0304 Code
I know I can fix this problem, but my question is which cylinder is #4? I don't see it marked on the engine. The counter guys at both my local parts supply stores (whose initials are A and O) can't even look it up for me. If #4 is on the front of the engine, then it's an easy fix. If it's on the backside, then the intake manifold has to come off to get to the plugs and coil packs. It's a bit more labor. I can do it, but I'd rather not have to.
View 1 RepliesSilverado :: 2003 - Intermittent CEL Code P0304 / Misfire On Cylinder 4
My 2003 Silverado 5.3 has an intermittent CEL. I plugged in the reader and found code P0304, misfire #4 cylinder. I changed the coil, swapped the spark plug and wire from #2 cylinder to see if the code would follow. Nope, didn't follow. I swapped the injector also, same results. My daughter decided to borrow the truck and drove it so low on fuel that the low fuel light came on in the drive way. I added about 4 gallons of fuel and now the light went off. I started the engine after a jump start, and the engine really runs rough and now won't stay running. I am thinking that the fuel filter is probably needing changed because of how low the fuel.
I haven't checked the fuel pressure yet and will do that today. Now, what really puzzles me is the intermittent part. Sometimes it will run with no problem, but then the CEL will come on and the fun begins. The Chevrolet dealer says it's caused by the valves turning in the head and when it reaches a certain spot, it detects the misfiring #4 cylinder resulting in the CEL. If I pull in the driveway with the engine missing, go back out in a short time, start the engine and it runs fine. Same thing if it's running fine and I can start it and the CEL blinks and it begins missing, but may stop and run fine. I am stumped and not so sure about the turning valves.
Ford Ranger / B-Series :: 2008 - CEL Code P0304 / Misfire
2008 Ranger 3.0L. I am trying to figure my next step in diagnosing a #4 misfire. At regular speeds I really dont hear it or feel it, mostly at idle warm or cold. 3.0L with 275,000 kilometers on it , reg oil changes.The CEL is on, but not blinking. Pulled a p0304 code. I then changed out the bosch plugs I had in with ford plugs and wires. The #4 plug looked okay just bigger gap. Still got the code.
I hooked up a sparkplug light to the coilpack and did not see any missing flashes . Changed fuel filter, checked fuel pressure,all within specs. Changed the oil and did not see anything in it. I read that it could be an injector but I have to remove the intake manifold to get at it. I also read to check compression. I figured if I have to take off the manifold I would put a new injector in, instead of switching them around. What is the most common cause for this code?
