a cople of these codes are transmission modle related. if your battery is in poor shape you may be getting false codes or you may have a problem with teh trans module or shorted wires.two fo the codes are throttle related. you might try cleaning yoru throttleplatewith choke cleaner as well as your iac vave and tps switch. clear your codes and see if they come back. keep in mind you have two tps switches and will need to clean where then contact on throttle body. have a trans pro look at the other codes.
