Subaru - Liberty :: Can't Go Faster Than 15 Kms - Intermittent Check Engine Light?
So recently i knowingly purchased a car with a blown head gasket. Got it fixed at the mechanics and also changed the timing belt / serviced the car. The car also had intermittent check engine light however the mechanic said it was just the O2 sensor or something and it wasn't worth fixing ($300 to replace it).
Now the car (automatic subaru liberty) drove fine for the last two weeks but my brother took it out to go to the snow and on the return trip the car starting to emit loud clunking sounds from the engine, the brake system warning light also came on and power was reduced and my brother pulled over, and checked it out. The car starts, but its only limited to around 15km even when flooring the car. The car free revs in neutral but emits a cracking sound.
Do you think the transmission shit itself? On cold mornings the car would take about 1-2 seconds to change engage drive / reverse.
Caravan/Voyager :: 2002 - Check Engine Light On / Intermittent Misfire
I have an 02 Dodge Caravan 3.3 L Flex . It had initially stalled and wouldn't start. Check engine light was on. Had it towed to a Cert Mech. He said it needed a "Major" tune-up. I let him do this. It included: New Coilpak, plugs, plug wires, cam-sensor, crank sensor. That's what was on 1st invoice.
It started, but was still running very rough. He then recommend a new PCM. After choking on his estimate, and paying the initial invoice, I decided to let someone else have at it. Mech # 2 installed a "Rebuilt" PCM, New Battery, and a PCV Valve.
It runs good now BUT, ...It has this weird idle Misfire. The only time it happens is at a stop light when at idle. And it doesnt do it all the time. This check engine light is not on... At this point, all I want to do is sell it.I have over 1K in repair costs and still can't get rid of this misfire.

View 3 RepliesPassat (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.
Ignition - Civic - Honda - Misfire :: 1996 - Check Engine Light Is On / Code P1382
The check engine light is on in my 1996 Honda Civic. The code for it is P1382, which is supposed to be either a misfire or the ignition control system. It runs fine most of the time, but intermittently cuts out while I am driving sometimes. I have replaced the spark plugs and fuel filter and the check engine light actually went off after replacing the fuel filter, but came back on the second time I drove the car. The distributer was replaced not quite a year ago with a reman distributor.

I have a 2004 santa fe with a 2.7 v6. I have had a little misfire issue lately. I had a major power loss with a check engine light on it lasted for just a minute before it settled itself out. Had the code pulled at a local parts store. P0301 so I checked the plugs and they looked worn out. I pulled the upper intake and replaced the plugs and wires plus the upper intake gasket. I cleared the code and that seemed to correct the problem. Two days later, same thing happened. The engine seems to be running fine now. I wiggled the wiring harness to the injector and to the coil, no change in the way it runs. I was thinking it could be an injector or a coil pack.
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?

View 7 RepliesPrius (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 - Volkswagen :: 2006 - Check Engine Light Indicates Numerous Cold Start Misfire Codes
Car dumbie back again with another question.The diagnostic for my check engine light indicates numerous cold start misfire codes. The cylinders are OK. That was checked during the diagnostic.The fuel intake is carboned up. It is recommended that I clean the intake manifold. Does this mean cleaning the fuel injectors, the throttle body or both? 2006 Passat VW....
View 1 RepliesPrius (Gen 1) :: 2001 Check Engine Codes - Misfire In Cylinders 1 / 2 And 3
Toyota read the codes wrong and told me that I need a new hybrid battery. That is incorrect info. Codes P0300 P0301 P0302P0303. The codes mean misfire in cylinders 1 , 2 and 3. I have had injector cleaned in the past new spark plugs. If I drive it it gets warmed up and shuts down. It will restart and run maybe 7 more miles the same. The brake light comes on and I have to restart it.

Got a 1996 Ford Ranger with the 4.0L in it that has a misfire on the #3 cylinder and giving check engine code: P303. Have tried new plugs, wires, distributor, switching out the coil pack with a known good, checked injectors for pulse, checked injectors, moved injectors and still the misfire remains on #3. Removed the valve covers and all appears to be well.
View 14 RepliesSubaru - Outback :: Intermittent Check Engine / Code PO420 - Catalyst System Efficiency
My 2004 Outback now has 120K, has always been maintained and repaired at the dealership (except tires and battery), and has always run great! I've had the plastick-y parts replaced over the last few years including head gaskets when one cracked and made smoke. In July I got a jump from a AAA tow truck, who said my battery tested as needing replacement.
In September my check engine light went on, and the dealer found the code PO420-catalyst system efficiency. They didn't seem to look any further into causes. The cat converter replacement was to cost $2521. They reportedly tested the battery as OK as part of their routine checkup. I declined the new cat converter till learning more. Meanwhile, my check engine light seemed to cycle on, then off, then on, then off . . . every several days.
In December I had the battery checked at Sears, who replaced it under warranty. So I guess it wasn't okay after all. After that my check engine light stayed off for somewhat longer than usual, then back on for most of January. I was just about to give in and get the repair done when it cycled off briefly a few days ago.
I've lost trust in the dealership because of their battery check which differed from others before and after theirs; and for their lack of specific diagnostics. The light is back on and I don't know what to do next.
Ford - E150 :: 1996 - Misfire / Error Codes Came On
I have a 1996 Ford E-150 van that has a misfire. The plugs, wires, cap and rotor have been changed and I still have it. The error codes come up as cylinder 3. ( I was getting the same before I replaced everything.) Scanner also says lean on bank 1. It also says that the O2 sensor behind the cat is not doing much.
View 3 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.
Subaru - Legacy :: 1999 - Piston Misfire Codes 301
I get check engine codes p0301 p0302 p0303 and p0304. Sometimes just one or two sometimes all four. It only happens in fifth gear at or above 2800 rpm. There is no noticeable misfire; my gas mileage is 25mpg and like the advice below, I've changed the wires, and spark plugs but not the coils nor the injectors. I've reset the codes numerous times; it comes back regularly but only in fifth gear at the higher speeds.
The car: Subaru legacy AWD wagon 1999, 2.5 liter 5 speed manual transmission.
To state the obvious, checking for electrical problems is a process of elimination. I've included some points I got elsewhere online to narrow down the cause. What is not discussed, but has been brought up by parts salesman are the sensors. There's five, a cam and a crank sensor as well as three speed sensors. Which sensor that's failing would cause such specific engine codes.
Talking points:
"for piston misfires If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back."Check engine light comes back on
"If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs)."There are no noticeable symptoms.
"Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable)."Done.
"Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced."It passed smog with flying colors. I'm not sure how to check the coil packs but since it doesn't actually seem to miss, I'd think to look elsewhere. -- maybe I'm wrong here.
"I've also heard in other cases the problems were faulty fuel injectors." Same conclusion as above.
Golf IV / Jetta IV :: 2000 - Engine Light And Codes That State Misfire On 1 And 4
My daughter's 2000 Jetta with a 2L has an engine light and codes that state Misfire on 1 and 4. It is intermittent as it only misfires once in a while.. She is in Rolla MO, and I am in Detroit MI. A couple of years ago the car died when she was home and I found a swollen/cracked coil pack. I replaced it with an aftermarket. The plugs and wires were replaced about 30k ago with OEM parts. I am tempted to have the son in-law replace the coil pack with a Bosch unit.
View 3 RepliesFord Ranger / B-Series :: 1999 - Intermittent Misfire On Startup - No Codes
Previously on "This Old Truck": [URL] ....
Mileage now 298,5xx. Done since last report: Oil change and filter. Trans oil change (merconIII, no leaks apparent). Tires. Front brake pads. Clutch safety switch (was interfering with cruise control operation) Coolant replacement. (see below)
Rat damage related overheat (near total coolant loss, but no MIL) at 288k. (Rat suffered acute lead poisoning later that night) No sign of rodents since.
Fuel filter change (after onset of symptoms).
NO MIL/CEL, no pending codes. CEL/MIL operates on KOST.
Temps normal (190F +/-2 deg during steady-state cruise operation, fuel flows and fuel mileage have not changed significantly. (fuel mileage has IMPROVED approx 5%, possibly due to gentler/slower driving)
M5OD with Limited slip 3.73/ payload pkg II (1650lbs)
Symptoms:
- Intermittent misfire on startup, seems to get better as the truck warms up. (intermittent= some days it do, some days it don't.)
- Truck starts and idles well, even with misfire.
- Intermittent loss of power, usually worse on days when no- or minor- misfire at startup/cold idle. From the driver seat it feels like accelerating over painted lines on a rainy day. . . a couple revs of no power, then it pulls hard for a second or two, then misses a couple of shots, lather, rinse, repeat.
- Usually worse in higher gears; (not noticeable in first or 2nd, bad in 3rd at high power settings, now almost constant in 5th, to the point that truck will not accelerate below 3000rpm in 5th even on flat ground.)
- Fuel flows above 4GPH/ OBDII "LOD" (engine load) reported above 75% are typical during malfunction. (Fuel flows have been as high as 9GPH with no problems on other days.)
Symptoms started at approx 292k and have been slowly getting worse over the past few months. . . . usually worse at beginning of trip, fading to very occasional after 50 miles of high-speed driving. Some days/trips no noticeable malfunction.
Thoughts:
1) Ignition wires tired? (did visual inspection, no obvious damage, but no water spray test performed, but seems likely given that the problem is most evident in conditions that would lead to high cylinder pressures.)
2) Fuel pressure? (not measured yet. . . original pump but possibility discounted due to intermittent nature of malfunction.)
3) O2 sensors tired/rat damage? (Original units still installed/ no obvious damage on cursory visual inspection under truck)
4) Injector going bad or injector wiring rat damage?
5) Plugged catalytic converters? (no sound of blown exhaust gaskets, exhaust flows well at tailpipe, with puffs at misfire.)
6) Cam sensor? (never been replaced; known issue with this model engine. Had intermittent mystery squeak that came and went at approx 250k-260k)
7) Clutch slipping? (never had one do that; always lose the throw-out first)
8) LSD problem? (fluid level/ appearance ok, last changed 150k; would expect worse in LOW gears)
9) Blown head gasket/s?
10) Cracked heads/ block? (Oil and coolant levels and appearance normal)
So: That's the plan of attack. What am I missing? (Clutch last done approx 170k; burned throw-out, did disk, flywheel, pressure plate, slave cylinder while the trans was down. I did not open the hydraulics or disturb the pedal linkage when I replaced the safety switch. )
