Prius (Gen 2) :: 2005 - Misfire On Cylinder 1 And 3
Just today I acquired a 2005 Prius (trim level 1... so no options at all) in exchange for a cruddy old Ram truck and a dying Avalon. They had issues, but so does the Prius. The car has around 218K on it, I just replaced the spark plugs with NGK iridium plugs, cleaned the MAF, sort of cleaned the throttle body a little bit, and even swapped the coils around to see if the misfire would change. I also gave the car a new air filter.

I bought an 07 gen 2 a couple weeks ago. A couple days after I got it home the check engine light came on. I did a scan, it came up, misfire on cyl
1. I installed new iridium plugs, switched the no. 1 igniter with no.
2... code came back misfire cyl 1 again.
I then did an ohm check on the injectors which were all spot on, then ran the engine and listened with a stethoscope to number 1 injector and could hear it clicking. Next thing I threw a can of Seafoam into the gas, drove that tank out and then threw a can of injector cleaner into the next tank... I forget the brand.. it's that stuff they've been selling for a hundred years that has MEK in it.
Anyway... I cleared the CEL and it's been a couple days and about 50 or 60 miles without a re-occurrence. I'm wondering if this is a common problem with prius's? (I know... but I refuse to use the word Prii... it just bothers me) Because the engine is always under such a light load, I'd think it would be prone to carboning up and such. Also... if this light comes back I'm thinking the next thing I'll do is switch number 1 and 2 injectors to see if the problem follows it.
Prius (2004-09) :: PCV Can Cause Cylinder Misfire?
I have a 2005 Prius with 135K miles on it. and last time I change my PCV was 55K. today, my car is misfiring in cylinder. My mon has a Nissa Altima and did not change PCV since day one and one of the Cylinder was misfiring one year ago. My brother change the PCV valve for the Nissan and reset the ECU and no more misfiring. I am wondering if I should also change the PCV valve for the Prius to fix the misfiring issue. and Why is a bad PCV valve cause misfiring.

I posted this problem several months ago about a p301 code that my 2007 Prius has been generating. I eliminated all the easy stuff... plug, spark unit, fuel injector. Over the past year since I've had the car, the CEL light has gone on for a couple months then shut itself off for a couple, then back on ... probably has shut itself off 3 times in the past year, each time staying off about a month or two before coming back on. Some background on the car, supposedly the PO hit a rock and damaged the motor about 2 years ago and had the short block replaced.
Anyway, the CEL has been on again for about a month, and I got a notice for Illinois emission testing, so I decided to take it in to the dealer and have him do a diagnostic so I can get the emissions passed. After an hour and a half of testing they told me that the best they could ascertain, the car has been submerged in water, as there is a lot of rust in areas that never get any rust, and they think there's a short somewhere.
The service manager at the dealership said if it was his car he wouldn't spend the money for another 5 hours of trouble shooting, and if the car runs good he'd just drive it as is. They cleared the CEL and the service manager just charged me for an oil change as they caught a recall on the steering that hadn't been done and figured he'd let me slide on the hundred for the diagnostic.
Prius (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.
Prius (2010-12) :: Check Engine Light On Due To Cylinder 1 Misfire
I plugged in a OBD2 reader and its show misfire on Cylinder 1.
I haven't driven the car for 4 days, and when i started the engine this morning, the engine show knocking when the regular engine kicks in (rough). i will be bringing the car in tomorrow (dealer). my car is a 2011 with 16k miles, strange for this to happen so early in age.
Prius (2004-09) :: Misfire On Cylinder 2 And 4 - Car Severely Idle Rough
I own a 2007 prius, it has about 320,000 miles. It has recently been diagnosed with a #2 and #4 cylinder misfire. The car severely idles rough, but when getting in the gas it goes away. I have replaced the spark plugs, the old plugs were very white(lean), replaced fuel injectors, used fuel injector cleaner. I've sprayed carb cleaner around the intake to see if I might a leak--no leak. The motor uses about a quart of oil every 1,000 miles since about 100,000 miles. I'm just guessing, could it simply be low compression causing this? I pulled the new spark plugs after about 5,000 miles and they where white also.

I replaced a failing two way coolant valve and went ahead and replaced the coolant. After this the heater wouldn't get hot, so figuring there was still air in the system I added more (which it took)...and repeated that twice. (and opened the top valve to allow it to bleed). Finally heat.
I got up this morning and the heater still wasn't working....so I added more fluid....which it needed. Now I have heat.
BUT, The engine started running like crap. Code says misfire on cylinder 1. Changed the plug and coil pack. This did not work. (When I pulled plug one out the end of it was dry.)
Could it just be a crazy coincidence Immediately after I changed the radiator coolant that a faulty or clogged injector rare its ugly head? The car was running fantastic before this. I thought, before I check the codes, that some way maybe I overheated the car and landed with catastrophic issues.
I have 378,000 miles on my 07 pruius
Prius (2001-03) :: Cylinder Misfire P0300 - Error Has Been Occurring Almost Daily
General misfire when the engine light comes on. This error has been occurring almost daily, sometimes it pins it down to cylinder 3. My wife's nephew who is a mechanic says it could be the sensor, but I have only been getting around 30 mpg though the car seems to run alright. I did go ahead and get the plugs replaced, as I was told it could be a bad plug but the error light still comes on as before and the mileage appears no better. What could this be? I am retired on fixed income and dread the very idea of an expensive diagnostic & repair session with a dealer service. Their solution for about everything wrong has been to replace the gas tank (three times already in the life of the car). Last time that did not fix what was going on with the car..

So I dropped my prius off to get looked at for error code p0301 number 1 cylinder missfire. They ruled out Spark plugs, coils and fuel injector. What else is ther? Also could it be the battery or even gas?

View 4 RepliesToyota - Prius :: Check Engine Light Came On - Code PO301 / Misfire On Cylinder 1
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.
Prius (2004-09) :: Check Engine Light With PO301 Cylinder Misfire Code
I bought my 2008 Prius 9-14 with 29,000 miles on it. (rebuilt title-big mistake I now know). I found out after I bought it that it had sat for 5 years before it was rebuilt) I figured it was a miracle the hybrid battery even worked.
I had no problems until 2-4-15 when check engine light was flashing and the car was shaking. The local mechanic said was the “clutch” (torque converter), took the engine and transmission out of the car to fix it ($2200). But he realized the mass air flow sensor (MAP) was not working even after he put a new one in so had me take the car to the Toyota dealer. The dealer found a cut in the engine harness and advised me to replace the harness which he said would cost $2800. The local mechanic saw the cut via my cell phone photo and offered to fix it for free which he did.
The next day check engine light comes on after driven 25 miles with code PO 301. (means misfires in cylinder one). The local mechanic switches cylinder 1 with 4, same code the next day, local mechanic switches the coils to the cylinders, still the next day the same code. He switched the fuel injectors. Same problem of cylinder 1 misfire. He cleaned the oil out of the intake manifold, did fuel injection cleaning, and cleaned gunk out of the fuel line. Car would drive good about 20 miles then same check engine light, same code, sometimes code PO300 (random multiple misfires).
Prius (2004-09) :: Oil / Fuel In Intake Manifold - Misfire For All Cylinder And Reduce Engine Power Codes
I'm getting oil and fuel into the intake manifold every couple hundred miles. Oil level is in the middle of low and full mark. It's not like it's a huge amount of oil and fuel in the intake but it's enough to make the car misfire, bog out. Only codes I'm getting are misfire codes for all cylinder and reduce engine power code (forgot what code it actually is) but that's when the car completely shuts down and won't start with red triangle light. If I clean the intake out and unplug the battery for a few min I'm able to start the car again, but it will run really rough and white smoke will start to come out the exhaust (gas smell). I'm wondering if a bad maf would cause this. I've already cleaned it but still doing same thing. Don't really know what the specs or reading the bad is suppose to be so I'm kinda stuck to determined if I need a maf or not. Cars got about 242K miles.

View 2 RepliesRepair :: CEL / VSA Came On Again - Cylinder 3 Misfire?
My Honda's check engine light and VSA light were on. The diagnosis was cylinder 3 misfire, an apparent Honda problem and one that I've had fixed once before on this same car at the dealership where I bought the car. This time the tech said I needed the pistons replaced and that the damaged pistons had also damaged the cylinders so they needed to be repaired (not replaced), and that I needed new spark plugs. My car has been in the dealer repair shop since July 16 (3 weeks today). I've had cars in the shop before and know just a little about cars. Three weeks seems like a LONG time. My question is: Is this normal or not (I am a woman and I'm not sure the tech/dealership is being honest with me. They assure me that this repair can take a long time).

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.
