Re: Engine running rough below 3k RPM. Fine above it. ???
I've always been skeptical of that stuff but I suppose it wont hurt. I read I can add it to a full tank and it also acts as a fuel stabilizer, so why not?
If this was a carbed SBC I would have already placed the dizzy cap and the plug wires. But on this thing, I should be getting a code if it is misfiring, no?
