Coolant temp sensor, 2009 F150, 4.6 V8

Great video bro 😎

I did find out after changing the coolant temp sensor I also needed to change the EGR valve. Hard to say if both were at fault. I am leaning more to the EGR being the culprit for not wanting to start when hot, and a ruff idle.

Would it chug while trying to start when warm like it was flooded?

[@scottliggett7073]

While trying to start, it turned over fast. So it did not Chuck until after he was running, it literally sounded like I had a massive cam in the engine. After I changed the coolant temperature sensor it turned out to be the EGR that was causing all my problems. The EGR will cause your engine to chug while running, I do not know if it will do that while trying to start. Usually that is because of timing, or a weak starter. Possibly a cam position sensor?

I meant it did not chug, did not mean "chuck" spell check sucks

Thanks for responding. This is only on a warm start. It starts up perfectly after sitting for a few hours and runs great other than at idle and warm start. Could that be associated with a timing issue?? I did however find the wires to the CTS hacked up some which may… be part of my issue. Going to test electrical tonight after I take alternator off

I planned on replacing the CTS, EGR, PCV, and Cam sensor. Hopefully one of those will be the culprit. I have already replaced all spark plugs, injectors, intake manifold, cleaned throttle body, cleaned MAF.

That's the cylinder head temp sensor ....
