The motor has 150 hours on it, or a year and a half. Throttle cables loosen with time and screw up the Throttle position sensor setting and results in a TPS error on the diagnostics read out. Nothing wrong with the motor, the fix is to tighten up the throttle linkage and reset the TPS. I want access to the flapper plate, holding it shut, while to performing the reset. If I could remove the silence cover, the fix is a snap.
Hoping that someone with experience with my situation might help.
