    Where is eng computer on this pcs of junk ??
    will a 3.8L eng comp work in a 3.1L application ??
    Have high impedence code for #2 inj and eng temp gauge reads hot after 20 sec running
    have change inj, inj wiring, temp sendor 3 wire unit.
    now think it is the eng comp issue, one volt wave form and no spike at end.

    PCM should be in the airbox.
    The 3.8 PCM won't run a 3.1 unless it has been reprogrammed for a 3.1
    I drink..so consider that when reading my posts.
