So here's my thought. While I was at Autozone today buying a new PCV valve and IAC, I remembered someone on this thread saying that the coil pack can burn out your plugs and wires. Well, about 10k miles after replacing my plugs and wires, I tested the coil pack. Sure 'nuff it tested out of spec, so I replaced it. That didn't change anything so I kept on going. So while I was there today I ordered a new wireset and bought some new double plat plugs. I also bought some seafoam, because to be honest I wasn't all that confident with my cleaning job of the intake manifolds. So I bought 3 cans, one for the intake/cylinders (through the vacuum port), one for the oil (valves/lifters, etc) and one for the fuel system (injectors).
My question is, in what order should I do this? I'm thinking this:
1) Replace PCV valve, clean the hoses around it, and replace the IAC/IAC gasket.
2) Put a can of seafoam in the gas tank and a can in the oil crankcase. Then do the 3rd can through the vacuum port on the intake manifold.
- Run the car for a half tank of gas (~150 miles, probably take a week).
3) Change oil in the car
4) Run the rest of the tank out of gas and fill up
5) Replace plugs and wires
How does that look? I kinda made it up so if that's totally wrong, especially regarding the number of miles in between steps, please let me know.
Thanks again everyone.
