CHECK ENGINE light indicates #4 spark plug is misfiring, OK to drive?p SolvedSolved

#4 spark plug is misfiring, doesn't affect sound of motor: can I still drive it?

It really wouldn't be recommended due to the timing a misfire can mess the timing up which could result in well needing a new motor...11$ for a plug or $1000-$1500 or more for a new motor your choice

My check engine light came came on. Its been on for a week now. But have not had any issues with it stalling or not starting. What could be the problem?
Tooty from United States 7 months ago
My CheckEngine dummy light has been off & on (mostly on) for the last FIVE yearas. OBD code was 00171 - I'd clear the codes, clean the maf sensor, and the 02 sensor, air filter. Worked for about 20 miles, then it would light up and stay again. After I repeated the process (lather,rinse,repeaat) - I realized thaat besides a faulty blinker, I had absolutely no ther performance issues at ALL!
So, After this last round of OBD diagnostics I I had a EUREEKA MOMENT & fixed it for good!
How? I put a piece of black electrical tape on the dash to cover the light! NO PROBLEMS SINCE! :)

Check engine light flickers and the engine loses acceleration

Ford F-150 2012  57000 miles
When the truck goes over 4000 rpm the check engine light flickers for about 20 seconds, and at that point the truck loses acceleration and then it goes back to normal. The error codes I have are P0300, P0302 and P0306. Thanks for your help!

I have a Ford F150 5.4 v3 with a weird noise

Ford F-150 2006  180000 miles
Hello, I have a problem with my 5.4 v3 truck, first I thought it was the chain but after disassembling and changing the tensors I saw some damages, and then changed the oil pump. It kept doing the same noises, in fact you can hear it even more, and also it burns the raw gas. The engine is not vibrating anymore, but I don't get any warning or a check engine light

I had same problem with my 2008 5.4 Triton motor check oil pressure if low check thrust bearing mine had over an inch of end play ford replace my motor with a long block while under warranty how the low oil pressure told them it was the thrust bearing i have no clue. But it did and it cost me zero dollars to have motor replaced so i don't imagine it was a fictitious diagnostic one month latter they replace the transmission and said it was a related they said the motor caused the problem with the transmission total repaire bill compleatly under warranty was $16,000.00

Ruff idle cuts out while driving loss of acceleration

Ford F-150 2005 Extended cab 4.6 stx 321500 miles
Check engine light was on so had auto zone run a scan on it. And at that time my truck would barley creep down the road. Well holy crap a ton of codes parked it till was able to slowly work on it. First changed all spark plugs helped a little then all 8 coil packs. New throttle body new EGR valve. Got a little better new fuel filter. Still ruff idle and cutting out on exceleration. Used smoke machine to check vacuum leaks didn't see any smoke. Checked vacuum line from brake booster that hooks to back of intake seems intact. Brake light stays on mostly sometimes flashes on and off. I'm at a loss help me figure this out. Plz

Same problem,,,,help,,,I'm not gonna put a ton of money into this,,,any feedback would be greatly appreciated
Stranded redneck gal from United States 7 months ago
Well I guess nobody has a clue. I have changed the throttle body w new solenoid. EGR valve mass air flow sensor spark plugs coil packs I even made my own small key machine to check for vacuum leaks. Nothing I cleaned fuel filter and o two sensors. It has around 40 psi for fuel pressure. Help this country girl is tired of being broke down guess I'm gonna round up a old nag of a mule to ride to town and back. Saves gas... sorta
Backwoods G from United States 5 months ago
Check your duct work before the mass air flow sensor. Look for any hole or crack that could suck air. If it sucks air and begins to swirl inside of that duct work it will make it run rough. I’ve got a 99 F150 that had same issues i cleaned my mass air flow sensor, on underside of duct there was a rubber grommet that wires run through that had come loose, and a 1/4 inch gap where plastic met the fender. I secured and taped the grommet and taped up the gap and it instantly changed, runs like a top now.

Catalytic converters would be the place to look. Sounds to me that they may be clogged.

It sounds like you are experiencing multiple electrical issues with your 2003 Ford F-150. There could be a number of reasons why these issues are occurring, and it will be necessary to diagnose the problem to determine the cause.
Here are a few things you can try:

Check the fuses. The fuses for the dashboard lights, radio, and parking lights are typically located in the main fuse box under the hood. Check the fuses to see if they are blown and replace them if necessary.
Check the wiring. Make sure that all of the wiring for the dashboard lights, radio, and parking lights is secure and undamaged.
Check the electrical components. Make sure that all of the electrical components, such as the dashboard lights, radio, and parking lights, are functioning properly.
Check the battery. Make sure that the battery is charged and that there are no problems with the battery cables or connections.
If you are unable to identify the source of the problem or if the issue persists after checking these components, I recommend having a mechanic diagnose and repair the issue to ensure that the problem is properly addressed and the electrical system is functioning correctly.

Problems while driving

Ford F-150 2005  250000 miles
The truck has the check engine light on, but when I start it and accelerate it I get a wrench warning light and it starts failing and loses power, and the AC stops working. I had that problem before and using a carburetor cleaning product on the admission fixed it for a long time, but now it happened again and I can't fix it.

OBDI has power but will not send codes.

Ford F-150 1995 F 150 201513 miles
Just installed two new fuel pumps, dual tanks, trying to fix the problem did not work. When you first get in the vehicle it will start and run fine for 8 to 12 seconds then die as the check engine light glitches out. When you try to pull the codes with a paper clip same glitching problem. I guessing ECM, but really don't know. Anyone ran into this kind of problem on 1995 Model F 150

Recently my truck started shifting really hard once in a while. Now it does it most of the time. I'm afraid I'll break something or twist an axle. It's been showing a check engine light after I run it 5-15 minutes give or take for a month or so.
