Engine Mechanical problem
1999 Other GMC Models V8 Four Wheel Drive Automatic 206660 miles

I just replaced the head gaskets and my truck has a hard time starting and when it does it runs rough.
It keeps on giving me a code of P1345, about the cam senor and the crank senor not corroalting. What does this mean? And how do I fix it.

Do you
have the same problem?
Yes
No
