ok got a 2001 blazer has around 150k and dose not have enough power to get to 20kms per hour and wont rev past 2700 rpms parts changed so far are MAS, DISTRIBUTER, all changed FUEL PUMP and FILTER and fuel pressure seems ok any ideas would be great before i decide to just burn it

 

"seems ok" we need the exact pressure. blazers are picky on pressure. hit up autozone,oreillys etc and test the pressure. 60 psi key on,hold above 55 psi after 10 min.

 

my gage go's to 60psi and it and has an inch or so of blank space past that and it maxed out the needle and stayed the for 10 mins+
