It's certainly something I'd look into. I'm putting up with a slightly rough idle just because I don't want to sink too much money into what was a very cheap truck bought to do yard projects, but I suspect that will get worse over time and need addressing. I've already replaced plugs/wires/coil/igniter which made it much smoother, but it doesn't run as well as I would want from my regular vehicles.

I also need to address a crack in the exhaust header. Don't really want to pay a shop to custom-fab one for me, but no one has the part anymore.
