I have a 92 S10 4.3l Vortec V6 vin code "w" of course and it seems to be a little sluggish at times

i have to mash the throttle to get it going, when it gets going its great in the passing gear but its got a major weak spot in the 1500-2500 rpm range

is there any (cheap) way that i can fix this???

All I can say is that while I'm no expert but I do have a 96 Blazer and had that same problem and after countless parts, it turns out that replacing the MAP and MAF sensors fixed my problem.

I just hate the Blazers.........am getting rid of it this spring.
