I have a 1999 Ford F150 V6 it give a check engine code saying a misfire on cylinder 6 but it doesn’t do it all the time. When code is cleared it runs great for weeks but then starts to run rough and says it is running lean.
I’d try and find what’s causing the misfire…such as a bad spark plug or ignition wire, possibly a coil or ignition module or even a wiring problem. When it is acting up is the best way to try and find the problem.
So it wouldn’t be the computer module?
Ok thanks i will look into it next times it does it . I just don’t know why it doesn’t do it all the time?
Probably an intermittent condition due to a loose connection from wire to plug, or moisture, etc….sometimes those are the hardest problems to fix.
You said it. Thanks for your Help.
You’re welcome, good luck!
Battery Dies When Truck Off
You probably have a parasitic draw on the battery that is discharging it after it sits. Do you have any aftermarket equipment on the truck like an alarm, or remote start, or other accessories?
Ok, well I would recommend checking for a draw on the battery. Do you know how to do that?
Do you have a volt meter that reads amps?
Alright, you won’t be able to check for a draw yourself then. You’ll have to get it looked at.
Thank for the help.
Your Welcome, good luck.
Battery Draw With Key Off
Question: Why does my 1994 Ford F-250 still have power going to the battery when I turn my key off?
Answer: Not sure what you mean that there is still power GOING to the battery. The battery is what produces the power, not receives it. If you mean that there is a power drain of the battery when everything is off, this is what is called a parasitic draw. You would need to isolate the circuit that is staying powered up by removing fuses until the raw goes away, then fix the problem.
