my 2010 sentra 2.5 auto has a malfunctioning throttle body. Cleaned the maf and the the throttle body with the fluids you suggested. took it for a test run and about 10 minutes in I lost acceleration. managed to limp it into a parking lot and eventually home, That was yesterday Today I've been going through everything I disconnected /moved looking for bad connections. the throttle opens on key on position but only after I shut it off. Doesn't move with key on, gas to the floor, but it opens and closes once after the key is turned off. Would a relearn repair this or is the t.b. toast?
