TH E39M5 Posted September 25, 2022 Share Posted September 25, 2022 No, I doubt it very much as the throttle bodies and linkages are all deep under the plenum and inaccessible. I would also think manually moving the throttle motor while the engine is running could cause damage to it or cause the DME to have a major upset at the very least.
