I pulled the spark plugs and fuel injectors last night. The fuel injectors were pretty dirty on the outside with baked on buildup and crud. I'm assuming these have never been pulled before. The rubber seals that fit over the injectors had baked onto the injector although they would spin. I had to end up using pliers and a razor knife to get them off. That process took longer than expected. I'm using emory cloth to clean the outside of the injectors but leaving the inside alone after discussing with my parts vendor. Once I do the flow test in the near future, I'll determine if any need to be replaced. They're $60 each, so replacing all 6 would run me $360 plus shipping. In this pic, you can see the one I cleaned with emory cloth on the far left.
The spark plugs were very tight. I had to carefully remove them using a little WD-40 and a cheater bar. They broke loose and all the threads look ok so I'm not too worried about the threads in the head. The plugs were AC Delco brand meaning they have been replaced at some point since the car was new. These plugs are not recommended by the vendors so I'm glad they're coming out. I didn't see any evidence of problems with the old plugs. They are worn but no red flags. I numbered them to each cylinder where they were installed.
