I've had my 1992 S-10 Blazer for a litle over a year, and it's been a great first car for me. But lately for about the past month, it has been running a little rough, and I tried cleaning out the injector, which made it bearable for a while. I also changed the plugs and wires and distributor and rotor as well. It would idle and run very rough and not accelerate until I would jam on the gas, and it would perk up and be ok. Until one day I was at a stop sign, and I let it idle. It began running really rough, and died out. I haven't been able to get it to turn over, so I'm wondering would this sound like a fuel filter/pcv issue, or something more serious?
Any input would be greatly appreciated.
