Prius (2004-09) :: Engine Light, Error Code P0301 Came On

So I changed my spark plugs, due to an error code saying p0301 which means cylinder one misfiring. I reset the engine light disconnecting the negative battery terminal. Once it reset it ran rough for a few miles. I put about 50 miles on it and it seems better.

Prius (2004-09) :: Code P0301 - Cylinder 1 Misfiring During Warm-up

I have a 2009 Prius that I purchased 6 months ago and have been really happy with it until the last couple of months. As the weather is getting colder appears I have a misfiring problem on start-up

I have had this problem now for a little while and have been trying to get it understood before paying $$ at the dealer for "maybe" solutions.

It started as the weather got colder. Intermittently the check engine light would come on. Then after a few days would go off.

I have considered water in the line: fuel injection cleaner/antifreeze

I have considered bad gas in the tank: problem persists several fuel tanks later

I have recently purchased a trouble code reader/diagnostic that plugs into my laptop. Trouble code is p0301. Cylinder 1 misfire.

I have taken it in to the shop.They tried:

>>moving the ignitor coil from cylinder 1 to cylinder 4,
>>and also tried moving the spark plug from cylinder 1 to cylinder 2.
>>performed compression test. Ok

The dealer suggests replacing the injector line for $1400+.( They did this with warm engine. They have not diagnosed cold engine yet. That is new, read more,...) I still have 5K kilometers left on the power-train warranty. If it is power-train I would like it resolved before warranty expires.

Now. Some new info as of yesterday:

Up till now I was not using the diagnostic monitor real time. but that started yesterday,... Last night when I got home from work while the engine was still warm I connected the diagnostic monitor and went for a drive. Every few minutes I would pull over and refresh the cylinder misfiring data. I had hardly any misfires across all the cylinders at all. Maybe 1 or 2, here or there over the span of a 10 minute warm engine ride. Up and down hilly terrain. Nothing that came close to triggering the p0301 trouble code. I parked the car outside and let it rest overnight.

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?

Lexus GX 2004-09 :: RPMs Started Surging While Idle And High Pitch Humming Noise When Accelerating

My girlfriend has a 2008 with around 120k miles on it. It's been pretty flawless but yesterday the RPMs started surging while idle and made kind of a high pitch humming noise when accelerating.

Today on her way to work she said the radio was going in and out, the battery light lit up and then the rest of the dash lights came on, and the speedometer stopped working.

What could be the problem? Could it just be the battery?

Prius (2004-09) :: 2005 - CEL Started Blinking And Engine Shaking / Knocking

Driving home the other day I noticed some vibrations up front. Reminded me of out of balance wheels. Then the check engine light started blinking. Then it was on steady, then blink, then steady... Took it easy the rest of the way home. Code reader said P0138 Oxygen sensor circuit high voltage bank 1 sensor 2, and P0304 Cylinder 4 misfire detected. At home is where I saw the engine shaking and extra noise from it (visions of piston rod slapping around in there). Removed plugs (original? tough to get out!), compression tested all 4 cylinders (130 to 140), new spark plugs (had they been in there for 196K miles?). Start engine and same, shake shake with some extra noises that weren't there before (car just sitting in driveway).

Volkswagen - Rabbit :: 2008 Car Started To Rev A Bit / Idle Has Been Rough With Some Light Shaking

I have a great vw 2008 rabbit with 115,00 miles on her. I just completed a round trip. On my way back during terrible stop and go Washington DC traffic..I noticed the car started to rev a bit. After that the idle has been rough with some light shaking. No engine light, but it does sound almost like it is choking a bit. Not extreme..but definitely not the smooth engine sound I had. I am guilty of NEVER HAVING MAINTENANCE on her..so I had new spark plugs put in and a new air filter. The problem is less..but the idle is still on the rough side.

Prius (2004-09) :: 2006 - Got Codes P0301 And P0302 / Misfire At Low RPM?

This has been an ongoing issue with our 2006. We purchased the car about a year ago and have put on just over 8,000 miles. Rebuilt the battery pack and replaced the 12v battery. This is my wife's car and I have a 2005, so I have done some diagnostics, tuneup, and even swapped some parts between the two cars trying to narrow down the issues.

Only recently have codes been recorded. The car is has a noticeable misfire at low RPM. Here is what has happened up until now:

11/29/15 - replaced spark plugs - #1 was fouled so I swapped coils between cylinders 1 and 4

2/25/16 - replaced 12v battery with new battery

4/1/16 - P0300, P0301 codes were first recorded and reset to see if they came back

4/10/16 - swapped Integration Relay with my 2005 (part # 82641-47010). My 2005 ran poorly after the swap, so I put a used one in my 2005.

Lexus GX 2004-09 :: 2005 GX470 Shaking While Driving When Accelerating Above 20 - 25 MPH

I have a 2005 GX470 with about 50K miles. Over the last few weeks it started exhibiting a weird problem. When accelerating above 20-25 MPH it starts shaking. Not the steering wheel. The entire car is shaking as if driving over rocks. It is pretty annoying, and I am now concerned as it seems to have gotten somewhat worse than before.

Tires are rebalanced and rotated, so i dont thing it is that. My wife is freaking out, as she is driving it with 2 small kids.

Ford F-150 (2004-2008) :: 2006 5.4L - Shaking When Slightly Accelerating

Ok, I have a 2006 Ford f-150 5.4L engine. it has 88000 miles on it. Here recently it has started acting up on me. It starts shaking violently when I slightly accelerate going up hills at any speed. On level ground it doesn't do it. Going down hill it doesn't do it. When stopped it doesn't idle rough.

It does this shaking when I barely press the gas. When it starts I either let off the gas or I push the gas to the floor and it stops. What is going on? This is the first Ford I have ever known. I don't know anything about these vehicles. I have read it might be the coils and plugs but then people have told me it might be the torque converter.

Prius (2010-12) :: Stutter Or Shaking From Engine When Accelerating From A Stop

I've noticed that when accelerating from a stop and turning onto an adjacent street to the left or right, there seems to be stuttering or shaking coming from the engine. I'm usually in ECO and only 1/3 of the way into the "engine half" zone on the HSI. It's not consistent but has become a bit of an annoyance.

Prius (Gen 2) :: 2005 Car Started Shaking Like Sputtering / No Engine Lights

I Purchased a used 2005 . Everything was great all weekend long, but this morning, the car started shaking as I was driving it down the road. I drove my 55 mile commute, parked and took my son in to preschool. The shaking started when I left the school. As I was driving (around 45 mph, accelerating to 55 on flat road), the car had some definite shaking like a sputtering shake, but there was no sputtering noise.

No engine lights are on. Could this be a balancing issue rather than an engine issue? Or possibly a joint? Do these cars even have a flex joint?
