Hey guys I just swapped out the Fuel Pressure Regulator on my 2000 Blazer 4wd 4.3 vortec. That's what the check engine light code was telling me...so after removing the plenum and the throttle body and replacing the part and then all new gaskets and re-checking all the connections, it starts but when you put your foot into it, it seems to bog down...if I gradually climb to speed it seems ok but when I put it to the floor it bogs down and only the rpms seem to increase...did I miss something when we put it all back together? any help in the right direction would be cool....thanks Kenny
