Toyota - Avalon :: 2003 - Smoking And Misfire On Cylinder 2
May 19, 2012
I just bought a used Toyota Avalon with 135,500 miles on it. They sold it because it was smoking and didn't know what was wrong with it(they were an old retired couple). They were the only owners and it has never been driven hard or abused.... Anyway. I read online that unhooking the vacuum hose from the pcv valve may make it stop smoking. I unhooked it and plugged the vacuum hose and they were right. It stopped smoking after I got the rest of the oil out of the hose. I thought maybe the old pcv valve was messed up so I got a new one and hooked it back up but then smoking was back. So I am getting too much blow by in it for sure. I don't think the valve seals are leaking because as soon as I unhooked the vacuum from the pcv valve the smoking stopped. I drove it for 2 days with no smoke whatsoever. What could be causing the blow by to be so strong? It was strong enough to spit oil out of the pcv valve without the vacuum hose sucking it out(there was oil on the engine).
The check engine light is also on so I hooked it up to a computer at an auto parts store and it said I had a misfire on 2 cylinders(2 and 6). So I changed all the spark plugs and re-hooked it to the machine. This time I only got an error code for cylinder 2. Each plug has a coil so I switched the coil from cylinder 4 to cylinder 2 to test if maybe the coil was bad, but it still gave me a misfire on cylinder 2 only. I even swapped the plug from 2 to 4 to make sure the new plug wasn't bad. Still a misfire on cylinder 2. It is still smoking(ONLY WHEN VACUUM HOSE IS ON PCV VALVE) and check engine light is still on and error code says cylinder 2 misfire.

I experienced a misfire code for #4 cylinder on my 2006 Toyota Avalon approx 8,000 miles ago and replaced the three front bank coils with Beck/Arnley coils. I didn't realize they were made in china until they arrived. The car ran fine until today when I got another misfire code for the same cylinder. I still had the two old coils in the garage so I swapped out # 4 and I'm happy to report that solved the problem. My question is should I be concerned that the # 4 cylinder has gone thru two coils in 8,000 miles or chalk it up to cheap chinese crap replacement parts?

'07 Avalon with 169k miles. I replaced all 3 back coils and 6 plugs back in December when I had various misfires, but the most common code was P0301 which is cylinder 1.
Car ran great until last week when I made a hard left and accelerated. CEL started flashing, read code and it's P0301. Every time I accelerate half throttle or more I can set the code off, but then shutting down car and restarting it drives fine, until I go half throttle. Car runs better when cold, and worse when I turn left and accelerate.
As long as I don't mash the gas I can drive for a half hour or so without the strumbling/hesitation. Surely the new coil hasn't failed so soon, I hate to pull the wipers, plenum,etc. and buy another coil just on a chance that might solve the issue. Car is only throwing a P0301 this time, no other codes like before. I've read a clogged cat or sticky exhaust valve could cause a cyl misfire.

I have a 2000 7.3L f250 superduty. after rebuild and a yr now have engine smokes when you rev the engine and an imbalance on No1 cylinder causing injector to carbon up poss from prev misfires due to injector harness now solved? Found the turbo exhaust outlet pipe leaking oil we think because the wrong size clamp fitted. will fit new clamp tomorrow but if this does not solve problem what next? This has now cost thousands and still having problems...

I have a 2007 Toyota Prius with just under 30,000 miles. Yes, I don't drive all that much, which makes the Prius the perfect car. I get it serviced every 6 months by the dealer. So far, other than oil changes, the only actual maintenance has been tires, a 12 volt battery, and a $300 "inspection".
A few weeks ago the "Check Engine" light came on. I pulled the code P0301, which translated to "Misfire on cylinder 1". The car was running great at that time, and since clearing the code it has continued to run without the light coming on again. Given that my maintenance is more time-related than mileage-related, it's possible that the ignition system needs attention. However I'm reluctant to bring that up at my next maintenance appointment, because the guy writing up the service order will always answer "Yes" to every "Do I need ..." question.

I have a 1999 Toyota Corolla. 4 cylinders.
I was on the road about 2 hours from home when my check engine light came on flashing. It stopped flashing so I kept driving. Three more hours of driving at highway speeds and it only came back on once. I then took it into autozone and the code reader told me I had a Cylinder 3 Misfire. The guy told me to change my spark plugs and I would be fine. It was time for a spark plug change anyhow so I drove home and did it. After I changed the spark plugs the car did not start at all. It would cough and sputter and try to start but not actually start. Changed the spark plug wires and then the car stopped even coughing and sputtering. It just didn't start.
I then noticed that my fuel line that feeds directly into the engine was rotten right next to the engine and if I pushed it in I could get the car to try to start. (Try and fail, but at least try.) The fuel line is a molded piece of rubber that flares at each end. It was one of the flares that was rotten and didn't seem to be sealing anymore. The hose is 7 mm inner diameter in the middle and about half an inch on the ends. I took some 3/8 in fuel line and used it to cover over one of the flares. The car tries to start now but wont. 3 of the four cylinders crank. I don't understand how I could break my car on such a simple repair job.

I have a 2000 Toyota Avalon XLS with 134k miles, engine is a v6 (3.0). It has a rough idle and a steady misfire. You can drive it sometimes and it will run perfect and you can drive it sometimes and it will misfire. I am getting codes P1150, P0300,P0302, P0304,P0306. Driving me nuts.

I recently purchased a 03 Camry XLE V6 love the car, but the engine has been giving me trouble. Since owning the car in January it has been in the shop 3 times for a cylinder misfire on 5. They jave replaced the ignition coil, spark plug, and fuel injector and still would misfire, it might be a few weeks later, but it would still misfire. It is currently in the shop for the something, they have checked the fuel, electrical system, and compression tested the cylinder and all has comeback good.

I have an 03 Lincoln LS V8 136000 miles. Just bought it in mid June and it was throwing P0420 and 430. I changed out the Coils and plugs and that seemed to do the trick. Before I was getting about 18.5 mpg and after it went up to 22 mpg. Well this lasted for about 250 miles (about a week). Now I have developed a really bad miss on #7,and a sometime flashing CEL, changed out the coil, no change. My question could this be a fuel problem? I did have one thing strange thing happen before I did the coils and plugs. I was just pulling on to the on ramp stepped on the pedal and it was like some one turned the car off nothing let off the gas and it was still idling tried again nothing, pulled off to the side. turned it off and restarted and it was fine??? Plus the fact it seems now that I my have to do the solenoid in the tranny grabbing during shifts.

As the title states... 2003 Passat 1.8T. The car was running fine. Had a new timing belt installed. The Check Engine light now continues to come on for Cyl #1 misfire. Attempts to fix so far include:
1) New plugs
2) New coils
3) New injectors
4) new cam and crank sensors

So I've been having some problems with my 2003 Volkswagen Golf lately (2.0 L gasoline engine, 98k miles). It started with an engine coolant thermostat code. This was repaired by replacing the thermostat and housing. Shortly after this fix I began to get a misfire, especially on rainy and humid days. Checking other forums I discovered that this was probably the result of a bad ignition coil.
The coil, spark plug wires and plugs were all replaced, but I am still getting a misfire. The idle is very rough so I've heard that it could be a bad fuel injector or faulty ground (though with the new components the other three cylinders sound cherry). The next step would be to purchase a "noid" test light and determine if the electronics to the injector are bad. I've also read that it could be a vacuum problem. There is a smell of unburned fuel when the engine is running.
How was it repaired? I'm quite good with the mechanical parts but lack the diagnostic tools, vacuum testers, multimeter and other such devices for performing complete screenings of the vehicle. Also, I can't drive it out to the local auto parts store to read the new error codes anymore. Finally I've got a "Chilton's" for the car but if there is a better manual available (better pictures, more descriptive instructions).

I have a misfire on cylinder #5 on my 03 Chevy Venture with a 3.4L, I changed the #5 Injector because the shop I took it to said that's what it was. But the same code came back for misfire cylinder #5, would a bad plug or wire cause the same code to come up.

I just picked up my truck from my mechanic after he was trying to determine what was causing a misfire in cylinder 3. He swapped coils and then did a compression test and found the following results in cylinders 1 through 4, in order: 143, 132, 57, 151. He said I need to replace the engine or start with adding Engine Restore. Is there a chance I don't need to replace the engine? Could it need a valve job?

My truck has developed a misfire on cylinders 1 and 5. The OBD2 scanner at autozone says code P0300, Po301 and P0305. I bought a new set of plugs and wires. Problem still there. I then replaced the both coils. Problem is still there. Is there a control module or something that could kill those 2 cylinders like on the older trucks with distributors?

My car is misfiring, as in acceleration 90% sputters until I lay the pedal to the ground, which obviously isn't good for my gas. What do I do? I can't find anything online and I don't want to be throwing money into things that don't work.

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.

I have a 2003 Jeep liberty sport with 175k on it. it has a misfire cylinder 2 code. I replaced the plugs and coil packs on all 6 cylinders, noid light test on wires, compression check in all cylinders, everything works so far. I still have a check engine light for the misfire. I don't know if maybe the injector is bad for that cylinder, looks like it was recently replaced as with the other 6, or i have a leak of oil or air or coolant into that side either from the head gasket or intake gasket. the valve cover gaskets have been replaced recently as well.
