My exhaust flanges started getting bad last month so I got them fixed the
other day along with taking off the catalytic converter and adding a
resonator. But anyway sometimes when I force the fuel to my 91 4x4 GMC 1/2
ton she hesitates to go and bucks then when I let got the fuel she is
perfect. No codes show up just the loss of power.
Anybody care to answer this one with opinions?
