OK well I went through some flooded streets yesterday and got a CEL, it was P0300 & P0305 misfiring cylinders, multiple & #5. Car was hesitating badly especially above 2500RPM. Car has 132K on it and I've never changed the plugs so I thought this the perfect opportunity to do so. I went to AutoZone and was kinda surprised that there is no "wireset" for this engine, only the coils/wire & boot sets. So I got the boot sets with the little coiled spring looking thingy in them(4.99 each) and a set of Autolite Platinum plugs.
I took the small metal rods that were in the stock spring thingys and put them in the one I bought at AZ, anyone know what these are and what they do? I should have taken a pic but forgot about it. Here's a pic of the boots/wires I bought at AutoZone, they didn't come with the little metal rods in them.
When changing the plugs I was surprised to see some OIL in the Throttle Body and also around the seals for the IM! Is this normal?? In this pic you can see the oil dripping out of the TB
Also the EGR was super filthy on the nozzle part that sits inside the IM so I cleaned that off with some acetone.
The plugs on the front cylinders were really good looking but all 3 rears #123 all looks bad to me. Here's a pic of the rear plugs.
