I have a 1989/90 model year classic. Recently it had a blocked air filter, piece of kim-wipe, this caused the hose from the plenum chamber to the air flow meter to collapse inside, all now changed for new parts, including air filter, however since this event it now cough's periodically and at a steady 65 mph cough's/hicough's badly about every ten second's, any clue's?
