My truck has a rough start, idles really rough stalls out I have codes c3201, p0301, p0172, p0175, p0302. I've changed the spark plugs and it isn’t any better coils are fine what do I look for next? I’m thinking maybe EGR valve stuck open but I’m not sure.

Hi,

The codes are two-cylinder misfires and a rich fuel mixture. The C code you provided isn't listed for this vehicle. Just to confirm, this is a 5.7L V8, correct?

Let me know about the code. Also, you may want to check the fuel pressure to see if there is an issue.

Here is a link that explains how it's done:

Let me know about the code and what exactly has been done so far. For example, how were the coils checked?

Let me know.
