Still need the codes.
Injectors can go "bad" in a couple of different ways; all they are is an electromagneticaly controlled nozzle. When the ECU "fires" the injector, it pulses a ground circuit for 4-8 milliseconds, the electromagnet powers up, the valve at the bottom of the injector opens, and the fuel shoots out, under pressure. The wire can be bad/chafed/corodded/ The electromagnet may be weak. The nozzle may be stuck. Lots of things. But, to put in an injector for a number 4 cylinder misfire (p-0304 code) would be one of the last things that I would do.

I would check to be on the safe side the fuel filter is going in the right direction. The arrow is pointing towards the engine away from the fuel tank, Then you need to make sure the fuel pump wiring connections are good contact and did not come loose when driving.

fuel pump sock or try the egr valve to see if it is stuck open all the time. can't remember if that one has the digital one and a vachumm type as well, next would be the evaperative canister purge valve.

Had a 94 Olds Bravada that did a similar thing and it was EGR valve on the front of the intake. It' s easy to take off and clean with WD 40 and if you have an air compressor blow it out good.

My 2004 had the same issue and i replaced the transfer pump. It started right up and ran fine until the next morning i was driving it stalled. Now it won't start up not even with starting fluid.
