I feel silly asking this question, but how in the world do you remove the fuel injector plugs on a 2002 Yukon with 5.3L Flex Fuel Engine. I dont want to force anything so I dont mess them up. It actually says press/slide on the side of the plug but you cannot press anything where it says press. Please help. Such a simple task is taking so much time, LOL. I think these have the CPA Connector Position Assurance plugs on them. These plugs are different than the ones without Flex Fuel.
