Why would you change fuel injectors?


Mail them away to be ultra sonic cleaned & tested only,
expensive proposition that was!

The MAP Sensor failed a test also?

I googled the P2431 & seems like a Secondary Air Injection
System Pressure Sensor ,hopefully that will get you close

Google it-- not easy to find some of those codes

Codes come back because you haven't found the fault
that set the code.

You working on things from yester year --not todays techology
