    1998 MPFI Conversion & 0411 Source?

    Is the SKP SKFJ504 on RockAuto (~$350) a good option or is there a better choice? And then another question, whats the best source for an 0411 PCM? Should I search FB Marketplace or should I purchase one from an online retailer? I was told Black Bear is hit or miss for tuning them too.

    Truck randomly dying when stopping and bad smell when starting truck.

    My 1990 C1500 has died twice while coming to a stop. It started back up after a minute of waiting both times. The smell when it starts is kind of sulfuric and it idles a bit rougher than normal. I’m thinking that it might be the EGR valve. Any thoughts?
