'90 Cutlass Supreme 3100 PFI

[Scott Linder]

Thomas,
unhook injector harness at rear of engine and ohm out the injector bank
pairs. Should be even on both pairs.  Call the shop and we can fax the
wiring diagram to you for exact wiring placement but really you should be
able to match them up as there are only 4 posibilities.
As a fuel injector recon shop we have the injectors in flow matched sets
for  $ 149.70 per set.
We are at  www.lindertech.com  take a look and let us know if we can help
you trouble shoot this vehicle.
It probably has a shorted injector coil.
