CEL Codes on 98 3.8l vert
 

I have a problem...the cel is on and, according to AutoZone code
scanner, I have the following codes: P0340,P1174,P1150,P1151, and
P1152. Anyone have any ideas what I should be checking/replacing? The
inspection is due by March 31st, so I have a little bit of time to
sort this out. Any help is greatly appreciated.
