| | Missing at idle RPMs
I have a terrible missfire that shakes the car at idle RPMs and the engine, overall, is lacking in power.
1994 5.0, bolt-ons, supercharger and brand new equipment to support it....
That's where I'm really stumped; all new plugs, wires, injects, fuel pressure regulator, MAF, spot-on tune. The car ran PERFECT for months leading up to this.
I checked for vacuum leaks and loose cables at lunch, to no avail.
What do you guys think?
