Hey guys, my wife's 96 blazer seems to have very weak low end power. I put in a new fuel pump, filter, cleaned the K&N drop in filter, I also gutted the converter when we got it, due to being clogged, all new plugs, cap and wires, can't find any leaks in the intake. It also has a hypertech programmer on it. 210k miles on it. Now what gets me, I drove another 96 with more miles, with the same parts on it, and it would run circles around this one. Anyone have any advice? Thanks

 

Rear end gear ratio?

 

3.42s in both 235 75 15

 

r u sure ur truck is taking off in 1st gear.

 

yeah, checked that too (father-in-law builds them for a living, had him drive it to make sure that wasn't the case.)

 

Have you ever cleaned the MAF? When I first got mine it seemed very slow, I cleaned the MAF and it was like a different truck.

 

I will try that next, just did the 99 front end swap on it. I scanned it for codes and didn't have any pop up though. I may just deal with it for now and build another motor for it with a small cam, ported heads, and a tune.
