Just a thought: When I bought my 90 Z from a Corvette-only dealership, it came with a receipt for new injectors. As it happened, they were NOS. Two years later some of them were reading in the "8's" (ohm-wise).
My point is, if replacing injectors, it is best to get exact part number for the alcohol tolerant injectors - and if you can install them yourself - to be sure the right ones are in FACT installed, so much the better.
BTW, I went with the
Accel 150821s 8 years ago, and she's still running great!
