yes all 4 02 were change after intensive search on fuel trims -means rich and +means lean. i found a trick to look for leaks but still working on it. because here in kissimmee fl dam heat index 100 to 103 each day. is hard to work out side,
with the truck running and the code reader set to fuel trim. while watching the readings spray carb or brake or starting fluid around disa valve while still looking at trim reading for big changes i found a small one around the disa valve took it out put some silicone around it waiting for it to dry to re test.all the seals are new when the intake was remove.but something simple sometimes can kick your ass .
