Prius (2001-03) :: 2002 Check Engine Light Codes For EVAP System And Misfire
My check engine light came on the other day, with no symptoms or problems. Today I stopped at the Auto Parts store and had the codes read. They were P0440, P0441, P0446, and P0301. They are for the EVAP system and misfire.
I had read here that one of the codes could be for the gas cap so I tightened it and then, also as read on here, disconnected the negative 12 V battery cable to perhaps clear the check engine light. I was curious.
When I started the car again, I now have not only the check engine light, but the red triangle exclamation point. How would you proceed? The 12 volt battery is around 5 years old. The entire exhaust system was replaced last year.(not O2 sensors though)
The hybrid battery was replaced at 70,000 miles and I now have 110,000 miles on it. I really wonder why disconnecting the battery and reconnecting it caused more error lights to appear? Also, the Auto parts guy said his code reader was fine for my car but I seem to remember here that there may be a special Prius one.
Passat (B5) :: 2001 - Emission Workshop / Misfire On 4 Cylinders And System Too Lean Codes
I am getting the dreaded emission workshop.
The codes i am getting are p0301-p0304 and p0171
Which are misfire on 4 cylinders and system to lean (bank 1).
Here is what I have done:
Got the 4 ignition coils replace, replaced the mass air flow, replaced the air filter, replace the plugs.
I just check the L wire and it doesn't have any cracks or holes
I don't know what to do next.
Ford - Taurus :: 2000 - Check Engine Light Came One - Misfire In Cylinders 1 And 3
I have an old 2000 Ford Taurus that has been having some misfire issues. I replaced the wires and plugs about a year ago and hooray! it worked... until about a month ago when the check engine light came one. Misfire in cylinders 1 and 3... again. I ran some SeaFoam through and it did okay until this week, when the warning/flashing check engine light came back.
It is idling very hard (expected) and feels like it is trying to stall, even before the misfire came back (also to be expected??). So here is the question: is this a coil pack issue, or something more sinister (and expensive)?
Lexus RX 2004-09 :: 2008 RX350 - Check Engine Light For Random Misfire On Cylinders 4 / 5 And 6
I have a 2008 RX350 with 68k on the clock. Received a check engine light for random misfire (P0300) and misfire on Cylinder 4 (P0304), Cylinder ,5 (P0305) ,Cylinder 6 (P0306). Question is what will be causing this to happen. I thought about changing the spark plugs to see if this is possibly the cause. but what else should i be checking?

My daughter 03 Prius died on her, the codes it threw are listed as P3108, P3191,P3101. We cleaned MAF and throttle and this did not solve the problem. We replaced the MAF with a remanufactured unit from O'Reilly's and now the car drives normally, but the check engine and red exclamation light are still on.

View 6 RepliesGolf IV / Jetta IV :: Running Rough And 3 Codes Stored - Cylinders 2 And 3 Misfire
So my daughter's 2000 Golf Mk4 with 160,000 miles on it was running rough and had 3 codes stored - cylinders 2 & 3 misfire and a 411 secondary air injection problem.
Having had the misfire code before I swapped injectors around and the error code moved cylinders with the injectors so I attempted cleaning them and also cleaned the throttle body and intake manifold. At this point car still running rough but also started smoking badly.
Replaced the following items:
- Spark plugs
- Spark plug wires
- PCV valve
- PCV hose
- Fuel injectors w/ remanufactured
Hose reconnected between secondary air injection pump and air intake - previous owner had duct-taped it in when he couldn't get it to seal I guess. I've never heard it run.
Car running better, idles more smoothly, doesn't stumble or stall like it did before, no error codes coming up BUT car smokes a lot and the fumes make me feel sick just driving it a mile.
The car had never smoked like this before, hasn't had a whole lot of love the last year or two but no real problems either so why the sudden smoke?
At first I assumed it was cleaner being burned off but that should have been gone in under a minute and this is on-going. It's bad enough to not only be embarrassing but apparently dangerous as the fumes are bad.
Ford F-150 - 1997-2003 :: Error Codes - Misfire Detected On Cylinders 2 / 5 And 6
My wife and I received her father's 2002 F150 4.2 5 speed 2 wheel drive truck after his passing. He purchased new plug wires and wanted to replace them. So, this weekend I put in new plugs, plug wires, changed the air filter, and changed the oil and filter. Started up and ran really rough. Threw my code reader on after taking it around the block and found the following codes...
P0316 Misfire detected in first 1000 revs,
P0302 Cylinder 2 misfire,
P0305 Cylinder 5 misfire,
P0306 Cylinder 6 misfire.
New plugs were Motorcraft plugs, but had skinnier center compared to the ones that came out of truck.
Where do I start? What do I do? I am really confused as I have changed plugs and wires before and always had vehicle run better or same as before change.
Ford F-150 - 1997-2003 :: Stumbling A Lot - Throwing Misfire Codes On 1 / 8 / 4 And 3 Cylinders
Recently bought 98 f150 xlt 3 door 5speed 4x4 4.6l 230k miles for $1k was throwing misfire codes on 1,8,4,3 cylinders. Usually throws two cylinders at a time and never the same cylinders consecutively
Parts replaced:
coils...msd blaster
belden wire
motorcraft plugs...when i did these it ran perfect for a tank of fuel...18mpg no stumble
two cans seafoam through the tank
tank was dropped and drained
fuel filter
one can seafoam intake cleaner
3" exhaust from the Y pipe back
MAF cleaned
Previous owner said to have tested and cleaned injectors but I am not positive it was done... I don't think its mechanical because it wanders through the cylinders and when i changed the plugs it ran spot on. it gets worse the warmer the truck gets also.
injectors?
clogged small cats?
sensor?
Passat (B5) :: 1999 - Check Engine Light On With DTC Codes / Misfire After Startup
The check engine light on my 1999 1.8T Passat is on. It started with a little miss right after startup. Then in neutral, after revving the engine to say 1,500 rpm and letting off the gas, it would nearly stall. I plugged in an OBDII analyzer and came up with codes P0102 MAF or VAF circuit low input and P0304, Cylinder #2 misfire. I replaced the spark plugs, as they were old anyway. Still the same symptoms. Then I replaced the mass air flow sensor.
The check engine light still went on after it was cleared, except this time it was P0302, Cylinder #2 misfire, P0102, P1613, Auxiliary inputs aux. outputs control, and P1426 Mfg. Control/auxiliary emission controls. Soon after, the car started running fine on it's own and I again cleared the codes.
Then a day later, the check engine light is on. This time, it is only the P1426 - Manufacturer control auxiliary emission controls. The Bentley manual calls it Tank Vent. Valve Open, which doesn't mean anything to me and the Bentley manual is of no luck. (The error code almost implies that it is the famous loose gas cap, but I have checked that - unless the gasket is bad). FYI: I have 99K miles on the car.
Ford Excursion :: 2001 V10 Not Running On All Cylinders / Check Engine Light Is Not Coming On
Bought a fixer upper 2001 v10 and it's definitely not running on all cylinders. Also the check engine light is not on and the PCM is not saying it's on (per my code reader) and it doesn't come on when I turn the key on.
Is it possible the previous owner had a programmer of some sort to disable the CEL? If the bulb were removed my scan tool would still show it on. Trying to get it to tell me which cylinders I am having trouble with.

View 6 RepliesFord F-150 - 1997-2003 :: Misfire Error Codes And Check Engine Light
So I have been having some troubles with my 2003 F150 4.6L ... Truck has been running rough and the check engine light was on so I decided to get the codes read and I got back P0302 and P0304, which from what I understand is a misfire on cylinders 3 & 4. At the same time I got Ford to do a little diagnostic and this is what they wrote for me:
"The connector for the number 2 coil is broken and will not stay plugged on to the coil and the number 2 coil is not working / replaced the wire for the coil still running rough removed the coil and plug. the plug was very badly fuel soaked started the vehicle to see if there was spark at the plug. OK. Suspect either a injector issue or a compression issue cleaned the plug seems better. "
So of course they quoted me for the works. They say I should replace the coils, plugs, and injectors??? I am pretty mechanically inclined and think I could change these things myself since I am on a budget. One tech told me is that the plugs can seize in these engines often and could scrap the whole thing??? Seems a little weird. If that happens though what could I do?
Subaru - Intermittent - Misfire :: 1996 - Check Engine Light With Codes 0301 And 0303?
This is my friend's car and I have never looked under a Subaru hood before. She is getting an intermittent check engine light with codes for cylinder misfires on one and three. Today, I inspected the plugs and all four looked identical, a nice uniform tan color and good condition. No sign of deposits or oil. Did a compression test and found the driver's side bank at 155/150 and the passenger side bank at 185/190. My question at this point is which side is cylinders 1 and 3? The front-most cylinder is on the passenger side. Is this the number 1 and 3? If so, then the low compression on the other bank cannot account for the misfire.
View 5 RepliesFord Super Duty (1999-2016) :: P0300 Code And Various Misfire Codes For Random Cylinders
New plug on right, lower bank 2 plug on left
Started getting a P0300 and various misfire codes for random cylinders. Truck has 95,000 kilometers so figured I would change the plugs. Several of the plugs on the lower bank on both sides were pretty much toast. Most of the plugs on the top looked good. All of the plugs had a small deposit where the spark hits the ground probe. Picture is typical plug from lower side. changing the plugs should make a big difference in how she runs and eliminate the codes.
Took right on 4 hours same as dealer said it would. I would have got it quicker but it was not a race.

View 1 RepliesHonda - Cr-v :: 2001 - Engine Light Remaining On With Misfire Codes
My 2001 Honda CR-V with 120,000 miles has been sending misfire codes for the past couple of weeks. I replaced the distributor rotor and cap, plugs (NGK's) and wires, and the light disappeared after a couple of driving cycles. Then, it came back on about a week later. I had it diagnosed at a shop for compression and everything was good. I had read about the valve issues so I had the valves adjusted.
The car seems to run without any hiccup at all, and its been over 150 miles since the valve adjustment but the engine light remains on with the misfire codes.
