Ford Aerostar :: 1997 - Misfire On Cylinder 1 / Bubbles Coming Out Of Radiator
Replaced pass side cyl head 7 years ago and now I've a misfire on cyl 1. Did wires and plugs as a matter of routine. Giveaway was rust deposit on rad cap. I always keep a strong coolant mixture and the rad is fairly new. Did a cyl pressure differential test and had bubbles coming out of rad. Funny thing is that had a rough few seconds on start, then smooth from then on. Getting my self fired up to tackle it. Have full gasket set and head bolts. Got a new head today. Am at 470k miles now.

My 2007 has 160k miles and at just over 100k I had toyota change all the fluids. That was about 3 or 4 months ago, it's a taxi. I started noticing the heat was only hot above 83, and sometimes not even hot at high. I thought I was out of fluid so I added to the overflow not wanting to open the cap on a hot motor. It didnt take much, but made the heat come back on above 80 degrees so I did nothing else.
Last night I had no heat again after driving about 200 miles. The heat came back after turning it off for a few minutes, but I stopped at a gas station anyway when I got off the freeway.
The overflow was full. It was also cold. So were the radiator hoses, but not what looked like power steering hoses next to it.
I check that belt pulley was spinning when the engine was running, it was. It a new belt put on by dealer.
The car doesn't show any signs of overheating, and is driven 300 or more miles a day in town and freeway. The motor was of course hot, but not overly so. None of the connected components were hot like I would expect if was overheating.
Prius (2004-09) :: CEL On / Misfire On Cylinder 1 Came Up
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 (2004-09) :: Coolant Is Always Overflowing To Reservoir - Air Bubbles Coming Out Of Radiator
I have a 2007 Prius, my coolant is always overflowing to my reservoir. It doesn't have any overheating problem, if I will fill up the radiator I could see bubbles coming out, How can I resolve this problem?
View 8 RepliesPrius (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 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).

View 4 RepliesPrius (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.

2004 5.4L ... Codes indicate a firing issue on #4 cylinder, figure it's the coil pack. They bought truck used a few years ago and plugs have not been changed since they have owned it. I was going to change plugs while I was under the hood. While checking threads on this engine I picked up on plugs being a major job unless you know the tricks. So what tricks do y'all have up your sleeve to keep from breaking plugs?

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.

2004 F150 XLT 5.4l (3v)... Problem started with misfire on No.4 and then I went through the tedious job of changing every plug (all 8 broke) and coils in an attempt to resolve the problem. After the changes I had misfire on no.1 and no.2, so I changed the injector on no.2 and coil on no.1 again + had broken pigtail wires on No.4 and No.1. Now I remain with a P0301 misfire on No.1. The problem won't go away, its fine idling, but misses bad when driving. The Snapon scanner reads fine for all injectors and compression reads ok also. The mechanics are baffled and what else could it be? (rail? computer? intake gasket?)
View 4 RepliesGolf IV / Jetta IV :: 2004 Overheating - Radiator Cracked And All Coolant Leaked Out
Ok so I have an 04 Jetta 2.0 and lately it's been overheating on me. The first time it started overheating was because my radiator was cracked and leaked out all my coolant, I swapped the radiator everything was fine for a while. The second time I started overheating, I saw my primary fan was bad it wasn't spinning at all, I swapped it everything was fine for another while. I also changed the coolant temp sensor, it wasn't bad it's just because the coolant flange was leaking coolant, so I changed it a long with the O-Rings and sensor. I also changed the thermostat just incase that was the problem but it wasn't.
I don't think the fans are turning on by them selves when they have too, but either way the car still overheats when I turn on the fans manually with the A/C. I'm not sure if the coolant is circulating, as the car only begins to overheat when I come to a stop and it idles. I have a feeling it's the water pump but I wanna be sure it is before I change it. What it could be? Things that I should check for that usually go out?
Golf IV / Jetta IV :: 2004 - MIL Flashing - Misfire On Cylinder 4
Just dug out my 2004 2.0 Jetta after sitting buried for 4 months. You can see a corner of the wheel there lol, its been a LONG winter. It is my car but my brother normally drives it, and while he is away at uni it just sits.
Anyways, dug it out to start it. Started right up, however after a bit the MIL began flashing. It was running a little rough. Took out my code reader and engine misfire cylinder 4 came up. The rpms are varying by 75~100 every few seconds, however nothing rough. It seemed to rev fine.
Before I put it away I got my brother to put some fuel stabilizer in the fuel. He now tells me that he put some in the oil too since it said "oil stabilizer" as well. It was a seafoam type brand... Not impressed with him there.
My question is could this just be the car waking up? Should I let it run for an hour or two to see if things work out?
