I am finding more pages that say the proper ohms is 11.8-12.6. I think my GM factory service manual has a misprint.

The injectors are GM Multec, and the injection type is MPFI. Not TBI. I highly doubt they are peak and hold. GM TBI injectors it shows as between 1 and 2 ohms.

That's possible they could have been clogged. I'll try some cleaner at the next fillup.
