Problem with 3.1V6 (Ignition related)

[Bruce Plecan]

I'd run a leak down test, next.
There is something oddd here.
I was just involved with a car that got 3 MAFs for codes 33 and 34, and it
was the ecm, and that had been replaced once (with a junk yard one), and it
set a 33...
IM little world I'd do the leak down, and then for grins an ecm.
