Don't worry about the code for the temp sensor thing, it's a useless code. I get it too and it doesn't matter for our 1995 ECM's. I have a 2500 series chassis, the ECM in the van is the same as the pickup just so you know. Everything in the van is the same as the pickup except the body.
Anyways, the sputtering can be a result of a bad fuel pump so check that, should read above 40 PSI at the fuel rail for proper operation. Should be very close to 43 PSI. Gauge pressure of course. Next thing it could be a faulty EGR that is sticking. Could be many things but these are a couple things I would check with first. Especially with the sputtering, sounds fuel related.
