Ford F-150 (2004-2008) :: Stumbling / Running Rough - Check Engine Light Is Either On Steady Or Flashing
Got an 07 Screw with only 50,000 miles. Yesterday, wife drove it home from work and said it would only do 45mph and didn't sound good. No warning lights were on, she said. I test drove it in the evening and it ran totally fine. Today, she drives it to work and said it ran real rough and "Check Engine" light was on. I picked it up from her work and it idles very rough and slow, and once you hit about 2000 rpm, it runs decent, maybe even normal. Below that, it stumbles and engine doesn't sound right. "Check Engine" light is either ON steady, or flashing. I don't have a code reader, so its likely going to the Ford Dealer Monday. Is there any way to read the code without a reader?

2005 F-150 4.6L 2WD, 268,000 miles....
Recently I got a flashing 'Check Engine' light and a rough running engine (along with a tapping noise) when I was passing someone (and pulling a trailer). I retrieved codes 300, 304, & 305. I can't swear to it, but I think the tapping noise started at the same time as the coil problem.
I replaced coils #4 & #5 (later that same day) and the engine smoothed back out but the tapping noise is still hanging around. The noise speeds up at higher RPM's and doesn't go away if I shift into neutral. Oil level and pressure are fine and I only use Motorcraft 5W-20 and Motorcraft filters (and change the oil every 5K miles).
Not sure if this is relevant: I think I have bad valve guide seals (blue smoke after long idles) but no other problems that I am aware of. It sort of sounds like a lifter, but is there a good way to pin it down? Is it possible that this tapping is related to the bad coils?
Lexus GX 2004-09 :: 2005 Engine Running Rough / Exhaust Leak At The Head
My GX had developed yet another issue. To start off my car has an exhaust leak presumably at the head. Thats what i been told. This condition would throw a P0430 code ( catalyst system efficiency below ) once or twice a week, which id just erase with my plug in tool. Im not sure if the new developed issue is related to it, but now the engine is running rough especially noticeable between 1000-2300 rpm. Feels like misfire. When driving i can feel a drone or a frequent shake if rpms are in that range or when unloading the motor and rpms are dropping. No codes! Timing belt was changed at 90k miles car has 150k now. Not sure if its due for another one now and this can be the cause.

Code says P1121 Accelerator Pedal Position Sensor Range/Performance Problem. I heard that was wrong and its really coolant control valve? The battery drains fast and the can runs like crap. Would this code be doing that to the car?

I have a 2001 elantra 2.0 gls. It is running rough with low power and flashing engine light. It may have a bad 02 sensor but when checked for spark only the 2 and 3 cylinders were sparking. I can confirm this because when I unplugged the 1 and 4 spark plugs it made no difference in the way it was running. Next I tested the resistance on the coil packs. Both were an even 1.5 ohms. How can it be that the coil packs are good yet the plugs aren't firing? I also have moved plug wires around and have had no success.

View 12 RepliesPrius (2004-09) :: 2005 - Heat Only Works When Engine Not Running
I recently ran very low on coolant with my 2005 Prius and had the overheat light coming on. Immediately before the overheat light came on, I realized that the blower was blowing cold air even though the engine was running. When the light came on, I immediately stopped and refilled coolant at the overflow reservoir and the radiator and let it run through a few times. I have re-topped off the coolant levels and it seems to be holding steady. Hopefully I have not done long-term damage to the engine, but that remains to be seen, and is, of course, very possible given that I let it get so low.
A symptom I have right now is that when I turn the car/engine on, hot air does not come out of the blower. If I remain in park, when the engine turns off, hot air begins to come out. When the engine kicks back in, the hot air stops. What this may be a symptom of?

My 05 was running rough and misfiring quite frequently. After much deliberation, I took it in for a diagnostic hookup. The dealer said my driver side cat was clogged. Lucky for me, I was just under the warranty period(79673 miles). I have had it replaced and I can feel a noticeable difference in the way it runs. Could a clogged cat have made it run that poorly or am is it just in my head that it is running alot better?

I changed the timing chain, phasers, tensioners, guides, and cam sensors and solenoids about 30k miles ago. Truck now has 170k miles. This past weekend engine started running so rough, it had the whole front end shaking. Threw 8 codes..1 bank..lean, bank 2 rich, timing retarded, cylinder G and F misfire, and more codes. It seems to have jumped timing pretty bad.
View 1 RepliesLexus GX 2004-09 :: CEL Came On And Engine Was Running Really Rough
So I've been sick for the past few days and my GX has been sitting in the driveway. I finally started it up on Sunday to run some errands and the CEL came on and the engine was running really rough. So I took it up to the dealership and had them pull the codes. It was showing a problem with the knock sensor.
I had to leave it until today so they could diag it further and see what the real problem was. Turns out I have a freaking rat in my engine and it ate my wiring harness. The service tech told me he jumped back when he took off the engine cover and saw an 8 inch rat scurry away. It is now sitting out in the lot until they get the rat out because they don't want it loose in the garage.
Ford Super Duty (1999-2016) :: 2005 F250 - Running Really Rough When Engine Not Fully Warmed Up - Glow Plug Codes
2005 F250 6.0L ... My truck is running really rough when the engine isn't all the way quite warmed up. once the truck is fully warmed up to normal running temp it runs good. I am getting four engine codes. P0672, P0673, P0674, P0676 These codes say 2,3,4, and 6 glow plugs have a open circuit. Can this be the cause of my problem?

2003 Ranger FX4 Flareside
4.0
Automatic
145,000 Miles
Here's my issue: My Ranger has been running like a dream until yesterday.
I took off on a parts run for my sons Ranger. I got to a stop sign and as I stopped, it started missing and barely running. I nursed it back home and checked the flashing CEL. It was giving me a misfire on #3.
Since I had been planning on changing the plugs and wires, I dove in and got it done hoping that was the cause of the misfire.
Started it up, same thing. I went to the next obvious item: coil. Replace it, still running like crap. Gave up for the night.
Today, I thought I would dig in using the tips here on the forum. Did the spray down...no errant spark anywhere. Tested fuel pressure: 65psi no drop in pressure on acceleration.
Started pulling wires off the coil one by one. Four of the wires resulted in running worse. 2 had no effect. #3 and #6. The coil was producing plenty of spark on all 6 ports.
At this point I was sure it had to be 2 bad injectors. Since I couldn't get injectors tonight, I moved them around after cleaning them a bit and tried my wire test again. The problem stayed on the back 2 cylinders!?!
I tested for voltage on the back injector plugs and I am getting voltage. I also used a stethoscope to listen to all of the injectors. The back 2 seem to remain silent. I have also unhooked the battery for 20 minutes to reset the PCM. Still missing and running rough....
Here's a list of what I have done:
Autolite Double Platinum APP5144 plugs. .062 gap
Autolite Pro Series wires #97051
BDW E97P Coil
New air filter
What should I do next? I really don't know where to go next.......
Prius (2004-09) :: ICE Running Rough For A Couple Of Seconds When First Started Up
Am I correct in thinking that Toyota recommend changing the spark plugs at 100,000 miles on the gen II?
The reason I ask is because on a couple of occasions the ICE ran rough for a couple of seconds when it first started up like it didn't have a spark or something on one of the plugs. Also I've noticed an slight drop in mpg, not just due to the time of year either. In winter I normally average 48-50mpg (UK) but I'm struggling to get mid 40's ATM. My pri has covered 75,000 miles so was thinking of changing them now to see if it improves?
Touareg :: 2004 VW - Check Engine Light Is On / Running Rough At Low RPMs
I have a 2004 VW Touareg with 116K miles. Yesterday the check engine light came on and she is running very rough at low RPMs. The manual tells me that there is either a problem with the exahust manifold or an O2 sensor is bad. It feels as if she is struggling for air. When you start the vehicle the check engine light flashes then stays on in the cluster. What can I expect when I take it in to the dealership? Is there anything I can check before I take it in?

I just had my 04 5.4l engine rebuilt. Ive driven it about 500 mi and it started running rough at a stoplight. I tapped the accelerator and it started running good again but service engine light came on. I pulled the codes and they were P0022, PO345, P0340,and P0430. It has done this several times now. Everything was replaced including the phasers, except for the camshaft sensors. Could they cause this problem?

I just started to have this problem yesterday. Engine light comes on and stays on. Engine shakes and truck won't go over 50 MPH. Autozone code checker came up with P0171.
Truck has about 95K miles and I had the spark plugs replaced at 75K miles.
Transmission was rebuilt at around that time also.
I only drove it to Autozone and back today to post the code and see what everyone's opinion is as to what's wrong.
Here's what the printout says : P0171 "Fuel Trim Bank One Condition"
