1993 sr5 extended pickup. So my issue is my pickup likes to sit there and think what to do when I hit the gas it gurgles like it wants to die. But never does. t then it catches on and goes. I have 4.10 gears and 4 in susp lift with 33's is that my issue. It's irritating me now. Fuel line?

 

Does it do it under load only or also in neutral/park?
