Did you also replace the spark plugs to try & cover your P0300 code? What type of plugs do you have in it?
For your p0200 code did you circumvent the controll to pulse the injectors? How did you check them1988 Chevy C-3500 2wd (no pic)

Definitely new plugs. AC Delco gapped at .040".
Have you cleaned the MAF? Are you running a K&N?When you hear hoofbeats, look for horses not zebras.
