Fluctuating Manifold Pressure Guage

[vasco]

A couple of weeks ago, the manifold pressure guage (2007 Ovation 3) on all screens began to wildly fluctuate.  Fuel flow and RPM did not change and i could not discern any difference in the way the engine sounded.  I called Matt at Midwest Mooney and explained the symptons.  He suggested the problem was either a bad transducer or the transducer was vibrating too much. 

On my last trip home, i dropped in on Midwest Mooney.  He tighted and re-secured the transducer and the manifold pressure guage has been steady as a rock.  He said it had to do with the 'crystal in the transducer...'. 

Anyway, a simple 15 minute fix.  To make things even better, they did not charge me and gas prices at KFOA was $4.52/gallon.  Just made my day!
