Or I might end up making worse, we'll find out.
'98-'05 owners, this is the part where you laugh and say, I told you not to buy an '06 or '07 aging fleet. Well, I didn't listen. I wanted the extra horsepower so now it's time for me to pay the vvti tax. I chose not to bypass the system because I'd prefer to have everything work how it's supposed to. That's just a personal preference given replacement parts are readily available, but I totally understand why people choose to bypass the system.
Some background, my '06 has around 153,000 miles and I replaced the air pump back in '21 because it was it was getting noisy and I was afraid it would fail. At that point, I didn't replace the starter or any of the other SAI components. Last winter when the temps dropped below 20 degrees F, I started to throw a DTC because one of the air switching valve was sticking open, or maybe closed, I don't remember. It would resolve itself on longer trips and would stay away until the next cold start.
I ordered parts over the summer and, because it's getting cold again, it's time to cross this project off the list. For anyone that wants to go down this path after me, here are some part numbers. Air pump isn't included (already replaced), but I am doing the starter while I'm in there.
At this point, I've got everything taken apart, but haven't started putting things back together again. The weather should be nice all week so the 40 can do daily duties. I need to order a few parts I wasn't expecting to replace, so far a few brittle cracked hoses and my heater Ts are probably ready after 8 years. I'm hoping to have it all back together in about 5 days.
Some tips so far, you need a top-side creeper or something that will allow you to get on top of the engine to get the intake off and reach all the crap you need to unbolt at the back of the engine. Thanks @Zuberg, for that heads up.
Despite what the FSM said, I didn't drain my coolant and didn't pull the coolant crossover pipe at the back of the engine. It's possible to pull the starter with all that in place, but I did remove the No. 2 air switching valves before attacking the starter. I also removed the bolt holding the electrical connectors on top of the transmission, this made it possible to remove the driver's side starter bolt. Thanks @2001LC for that tip. Once the starter was loose, I was able to turn it counter clockwise and remove the electrical connections.
My creeper.
The current state of affairs
I'm actually not even sure which valve was causing the DTC, but I do know I don't want to pull the intake again so I'm replacing all of it.
That's it for tonight, hopefully I'll get parts ordered tomorrow and maybe start putting things back together after the kids go to bed. Let me know if there is anything else I should to while "I'm in there".
