I like to research each answer before I get back to you to ensure that I give out the correct info. Thank you for understanding. Is the p0351 the only fault code you are getting?

sir

But you still have a [engine](/topics-engine-ford/) misfire on cylinder 1 but no code correlation to that?

that's the only code we changed the coils in the spark plugs I've changed the throttle body I changed the PCM computer I don't know what to do next help me please

Let me dig into this fault and see what I can find as far as common faults.

After looking into this issue for your specific vehicle the parts you replaced are the most common faults but the issue is most likely a wiring or connector failure. You will need to follow the wiring to that individual coil to cylinder 1 to find the fault. There is a TSB related to this but the fix is to replace the coils for the suspected faulty cylinders. When this code is activated this would indicate a cylinder 1 misfire for you. An engine misfire will cause sluggish acceleration. Think of it as plugging your mouth but trying to run full speed, you can do it but it will be hard. That is how your car feels going down the road. The computer will shut down the injector for the cylinder at fault. I have attached the troubleshooting guide for this fault. It has the wiring testing that needs to be done in order to find this fault. This will lead you or your mechanic towards the fault at hand. From here you will need to perform the repair and retest the vehicle. Making sure to clear the fault codes after the repair. I always shoot for a 5 start review. If you have any other questions or in need of any other help, please let me know. If you think my answer was not that of a 5 star rating please let me know what I can do to assist you further. I want to answer all concerns that you have about this issue. Tips are not required but greatly appreciated, I work hard to give you the best answer and appreciate the extra thank you on your side. Thank you for understanding and thank you for using Just Answer!

Question once I trace the wire if if the wires are good what's the next step I have a certified mechanic tracing the wire for me right now

If the wiring is ok then this will be an intermittent fault with a loose connector or a fault with a coil or the pcm that you installed. It would be pretty rare for another pcm to have the same fault so I would assume this would be in the programming on the pcm or fault in the wiring. I would suggest if this happens to watch live data while the engine is misfiring and then doing a wiggle test at all connectors.

Okay I'll be in touch thank you

Sounds good.

Hey brother thumbs up to you guys man it was the wire thumbs up bro I appreciate everything you told me

Perfect! Glad it was something as simple as that! Happy Holidays!
