Golf IV / Jetta IV :: Catalytic Code / Cylinder 3 Misfire P0303
I own a BMW not a VW! My 19yr old daughter purchased her first car a few months ago, an '03 Jetta 2.0L with approx. 170,xxx miles. Just after she got it we pulled a P0420 code, but it ran fine so we haven't worried too much about it. I've cleared that code and after about 2 weeks it will come back. Last week it started to have some issues with rough idle, stumbling/hesitation. I pulled the codes yesterday an in addition to the catalytic code is a cylinder #3 misfire P0303. I thinking the 2 codes are not related. I'm assuming the typical things to look for on the misfire are coil, wire, plug? Looks like the coil on this engine is a combined unit so no switching coil packs to see if the miss follows a bad coil pack.

I own the 2014 Santa fe turbo 2.0 litre limited which has 4000 km on it. Within 210 km the engine light came on 3 times. I took it into the shop and they ran a code of P0303 which is a misfire, they changed the coils #2 and #3 and cleared the code. The second time it showed the same code but the shop said it was in the history so that is why the same code came up again. They ran an update ECM? and all was good. Now the 3rd time they tell me no code has come up and can't do anything about the engine (they cleared it) but it was like chasing ghosts. My vehicle runs great so not sure why I am constantly having this issue.

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.

We got our latest Santa Fe computer email and it warned of an engine fault. The car itself was not flashing any warnings though. Took it to the dealer and they said OBD was throwing a P0303 cylinder 3 misfire code. They shifted the ignition coil, and replaced the injector and seal before resetting the code. They had the car for 3 days though. Car was not running rough or anything else you would expect from this type of issue. Still trying to figure out why we got the email with no indication of trouble from the car itself.

My wife's 2010 RX350 with 75K miles on it , the check Engine Light came up with code P0303 (cylinder misfire). Since the warranty is out already so I went to my mechanic and had the spark plugs and the back ignition coils replaced. After a week, the light came back on. So I went to the dealership and they said the engine needs to be taken apart because of low compression and valves could have carbon build up already.

On my way to work, my check engine light started blinking and car was sputtering (real bad on idle). I ran the code and it came back with misfires codes. I changed the coils/plugs, fuel filter and fuel pump last year. Can the coils be bad already? When I clear the codes the car will run fine for a little while. But after a couple miles CEL will blink and the car will run roughly again.

Golf IV / Jetta IV :: 2002 GLS 2.0 - Misfire In Rain Only And Check Engine Light Flashes
My 2002 Jetta GLS 2.0 is misfiring only when it rains out. I go to start the car and the car idles extremely rough and seems like it wants to die. I checked out the codes for the check engine light and I got misfire codes p0304 and p0300. Which is a general misfire detected, and misfire on cylinder 4. I noticed that when I misted the alternator during the day around 70 degrees with the car running the car would misfire and almost die out. I know you are not supposed to get the alternator wet, but keep in mind i did not soak it I misted water on it. I misted the coil pack and nothing happened. I replaced the spark plugs and wires a few days ago. But as soon as it rains my car does not idle right and the check engine light flashes.

So last Thursday I started my car up in the blistering cold and it ran fine for about a minute and started to misfire so I shut it off. It hasn't ran since. When that happened the check engine light was blinking because of the misfire. I didn't have a code reader at the time to read it. now that I got a code reader the damn thing isn't throwing any codes. it spits and sputters sometimes. I've had no previous problems with the car. Thinking It might be a weak fuel pump or bad coils and in not sure how to test them.

I have been a check engine light on and off for the past few months. I finally got the codes read and I have P2015, Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance Bank 1, and P0303 Cylinder 3 misfire.
The car had 80,000 miles, APR intake, Downpipe, Exhaust, and tune. When I had this work done I had engine problems and replaced the spark plugs and Upgraded Coil packs from the R8. Two years later and I get these error codes.
Nissan - Sentra :: Code P0303 - Cylinder 3 Misfire
It keeps reading the code P0303 "cylinder 3 misfire". All coil packs, fuel injectors, spark plugs have been replaced. The exhuast smells normal. The oil is the correct color(maple syrup color, NOT milky). It's not blowing through coolant. Compression test came back normal. It's not the cat converter because the exhaust doesn't smell like rotten eggs. The car is sometimes hard to start. it hesitates/stumbles and shakes really bad. It feels like its not getting enough power.

I got a check engine light. I went to Auto zone to get it read & they came up with a P0303 - Cylinder 3 misfire. Since I bought the vehicle a couple of months ago, I don't know when the plugs were last changed, so I decided to change them. However . . .
Is there a secret to getting the plug boots & wires out of the hole and off the plug without wrecking the wires?
Camry :: 2004 - Getting P0303 Code / Cylinder 3 Misfire
I have searched but with no solid answer..
What I got - 04 Camry, 231K, never had issues, do all my maintenance myself, brakes, plugs, oil etc..
#3 Cyl misfire..
Possible causes
Plugs, - Has been about 2 years since I replaced
Coil - Bought car new in 04, never replaced
Cat - never gave it a second thought
fuel injector - put techron by Chevron just about every oil change, I know I missed one here and there..
burned exhaust valve - say it aint so...
poor compression - I have to rent a tool...
defective computer - I don't think so..
GTI 337/20th Anniversary :: 2004 GLI 1.8T - CEL Came On / Code P0303 Cylinder 3 Misfire
So I have a 2004 Jetta gli 1.8turbo and my CEL came on last night from normal driving, after it came on it still drives the same. I had it scanned for codes and got the p0303 cylinder #3 misfire. wondering what could be the solution for this? I dont think its the coil pack because I had them changed at the dealer from the recall about 2 months ago (anyway to check?) Also I have 97,000 miles on my car and my last oil change I used 0w-40 oil. I know this is probably not the best oil to use at this mileage but I had an extra 5 quarts of them laying around so I decided to use it.

1997 chevy k1500 ... I have a misfire on cylinder 3 that i cannot figure out the cause. The idle is rough, backing out after starting is very rough, it seems to pick up at higher rpms but once the truck upshifrts to the next gear it shakes like a leaf in fall. within the past year the engine was rebuilt all new seals a new fuel pump, new injectors, new everything practically. so far i have done the following:
compression test results:125-130psi
fuel pressure test results: 50psi once primed, 50psi with engine running, no immediate pressure loss after engine is shut off
new spark plug wires
new spark plugs
replaced all four o2 sensors
Sierra :: Cylinder 3 Misfire Only Under Hard Acceleration / Code P0303
So my 2001 5.3L truck has 206,648 miles on it. Over the years, it's been serviced every 5K with the only big repair being head gaskets which were done about a year ago.
Two weeks ago, I hit the gas to merge into traffic and the SES light started flashing and I could tell there was a miss. I got off the gas and a few moments later, the light went out and the miss was gone. I pulled the code and it was P0303 so I change the plugs, wires, and the coil pack for Cyl 3 fuel filter and ran a double dose of Sea Foam through the gas tank.
Bad news is I still have the problem. The truck drives fine; in fact, I pulled my bass boat 75 mile round trip yesterday. Everything is OK till you hit the gas hard to merge or to go up a big hill or pass someone. When you hit the gas hard, SES starts flashing and there is a miss. I also noticed the valves ping loudly when the SES is flashing. The only code it's giving me is P0303.
Could this be a bad injector not delivering enough fuel at higher RPM/under load? I was going to swap injectors and see if the miss moves. Any tips on popping those injectors out?
Ford - Taurus :: Misfire Code For Single Cylinder P0303
01 Taurus, 3.0 pushrod motor. Single 6 pack style coil. I replaced worn plugs 2 months ago for misfire. Car seemed to run fine. Now, I have misfire again. Code is for single cyl, 0303. Would u expect plug to foul, or bad wire, or possibly bad coil? I don't know how these ford coil packs fail. Can u lose 1 or more spark outputs with them?

Just installed a short Ram intake on my 2000 Vw Jetta 1.8t. Had the Intake for about 250 miles and now the check engine light came on. Just pulled the code p0411 secondary air injection system incorrect flow detected. Is this just cause there is more air going through the MAF sensor?
