I recently finished installing a G3X with GEA24 and Garmin sensors and have been experiencing manifold pressure fluctuations. At WOT it is solid and at pressures under 20" it is solid, but between 20" and 25" it can move up and done rather quickly as much as 3-4" without touching anything. I've looked for plumbing leaks and wiring issues but so far nothing. I saw an old thread about putting a restrictor in the line, but am reluctant to do that without further research. Does anyone have ideas?
