i have a 2009 explorer sport trac with 174,000 miles when its cold it runs fine but once it warms up it begins misfiring the check engine l comes on i have had the codes read it has a bunch of codes for the engine,transmission,emission system.
When you have that many codes the only thing to do is clear them all and then wait for the CEL to illuminate again and when it does address the 1st code it throws.

Pressure clean your leaking fuel injectors.
Have a read of the FAQ section of this website to expand your diagnosis.
why do thank there leaking
A cold engine needs more fuel to run, however, once it warms up to normal operating temperature, it doesn’t require as much fuel & a leaking fuel injector/s may spray too much fuel & make the engine run poorly/misfire.
Can you tell us exactly what the codes say?

{black}:shocked: just a few eh.
It's unlikely that ALL those things malfunctioned at once.
Make sure your electrical sytem is in good shape: load test battery + alternator. Cables and grounds are tight and clean.
If it's not that, then you got some major electrical problem. Broken wiring harness, or connector not making good contact, water inside the fuse box, water inside the PCM etc....
Woahhhhhhhhhhh I did NOT see that coming...!!
