I have a 04 F-150 FX4 5.4L. The problem I have is my truck will idle rough and it shuts off when I'm parked. I pulled the codes and they are P2197, P2195, P0300, P0171, P0174. I thought it might be the MAF sensor but I put a new one in and it didn't get any better. Any advice would be greatly appreciated. Thanks

 

Anyone have an opinion?

 

I just Google'd one of your codes and came up with this thread which seems to apply to most of the codes you have.

That thread is for a 4.2 V6 that has an IAC and isolator bolts. Your 5.4 doesn't. However, you DO have all kinds of places to look for vacuum leaks.

 

Would the throttle position sensor have anything to do with my problem?
