I have a 2004 ford f150 4.6l. For the last week I’ve had 2 new codes which are p0106 & p0351. Since I got these codes my engine starts up fine when it’s cold but once the engine is up to temp and I shut my truck off and try to start it about 20 mins or half hour later when the engine is still a little warm my truck struggles to start. Any ideas what it could be? Anyone have the same issue with these codes?

 

Do you have any kind of test equipment to use? like a test light or DC Voltmeter

The codes have directed us to the system, now we need to do some checking to determine if the right information is getting to where it is supposed to go .
