Just curious what folks do for yearly maintenance for their FI'd cars? I live in the north east, so every spring I pull the car out and perform the list below. BTW, my car is an '04 coupe w/ turbonetics kit at 8lbs. of boost.

Here's mine:

* Remove upper and lower manifold, clean oil - carbon build-up
* Remove throttle body to clean carbon build up (much better idle)
* replace spark plugs (I drive roughly 6k a year)
* Change oil / filter
* Clean air filter with cleaner / re-oil

 

How do you get carbon in your intake and throttle body

 

Do you have any sort of heatwrap on your lines? If you do, another good thing is to either take it off or re-wrap.

Alot of people will use fire-retardant wrap and then just forget about it... Well, if you spill anything that gets onto the wrap, it just soaks in and can be a cause of fire. I have personally seen 2 cars catch on fire from having the wrap catch on fire.

Also, get youre fire extinguisher checked/maintained!
