Have been shopping for several months. Looked at probably literally 100`s of 2dr 4x4 98 and up Blazers. All I have seen are TBI. The latest model I`v found was were several 02s.

What year was the change? Is it still the W vin code.
Not a deal breaker on my purchase but am getting curious.

edit: Slight correction. I guess the fuel delivery type is indicated in the RPO.
Side note: Contacted several used car dealers during my search. Not a one of them even knew what an RPO code is.
