Get catalytic converter off of living room floor and installed.
Spark plugs and wires
Fuel filter
Clean air filter
Oxygen sensor
Swap coils
I was convinced the O2 sensor was going to be annoying, and only accessible from under the car. While down there I was going to swap the fuel filter. Spark plugs and O2 sensor were coming by Fedex, and we tend to be toward the end of their route (late day deliveries).
This is how it actually went down:
Car gets to the exhaust shop at 7:50ish in the morning. Goes on the lift and up in the air by 8:05. In conversation, they mention that they sell that same converter for $300 (I got it off of eBay for under $65). He cuts the old one out, and the new one slides right in, which confirms the NA Park Avenue got 2.5" piping, I was a little concerned about that one in all honesty. Mechanic was quite thrilled, as this was one of the simpler installations. Didn't even need to add piping. Clap off, clap on. I roll out of there by 8:30.
Take old unit to recycle. Subtract one slightly plugged stock converter, add $40 to my pocket (I was hoping for a bit more, but still acceptable).
Swing by AutoZone on the way back, pick up sparkplug wires (Duralast, yes, but already have lifetime warranty, so don't shoot me!), MAF sensor cleaner, and fuel filter. Swing by Harbor Freight to get the fancy deep sparkplug socket, only to find they don't have one. Settle for a standard with a shorty extension, also grab o2 sensor socket, as well as some other odds and ends, and head back home.
Meet up with a friend for lunch, had fun, and found out that Fedex made a delivery in my absence, plugs and o2 sensor (ACDelco BTW). Run home, grab those, grab tools, change clothes, run back over to friends house. Shaded carport FTW!
Pop hood, and track down o2 sensor to hit with penetration. The stupid thing is freaking next to #6 spark plug!
Swap front 3 plugs and wires (20 year old plastic plug wire guides were annoying admittedly), blast the o2 with PB Blaster again, and get 2 of the 3 in the back (2 and 4), knocking off some more of the plastic outer shell of the HVAC air box in the process.Then swapped out the o2 sensor (it was easier to get out then the spark plugs, I was expecting a fight), and bring it home with the last plug and wires.
In review:
I was reminded how easy this car is to work on and maintain.
Parts are cheap
The drive home after a tune up, smooth as glass.
Here's to hoping that my fuel mileage jumps a lot! Sub 20mpg with 50% highway mileage is kind of annoying, especially when all of the internet is watching on Fuelly!
Still have to do fuel filter, clean the air filter, and the coils have yet to be delivered. I plan to stretch her legs tomorrow though
Glad to be able to leave some positive feedback, instead of some rant about how a 20 year old car with 171k miles needs some attention. I really love the engine bay on this thing. Mechanic gloves go a long way, especially on a blazing hot engine.
Stay sharp my friends, and may the 3800 gods smile on your journeys
