Why is my 94 suburban sputtering out?

I have replaced the fuel pump fuel filter distributor cap and rotor ignition coil and plug wires, I have even had the gas tank cleaned out

Answer #1

This has a fuel injected engine. Try cleaning the injectors, and also look for ALL fuel filters along the fuel line path, because I’m sure there are more than one. Clean and replace as necessary. :) Another thing you can try is making sure you’re getting good compression in all cylinders and cleaning all your spark plugs (just make sure when you put them back in you don’t over-torque them). Just a few things to get you started. If all else fails, call the guys at Car Talk. That’s where I get my car knowledge from. :)
