My parents bought the 03 bonnie in 2006 and it was passed down to me in 2011. It is unfair to say it's the best car I've ever had, but it's true! It handles snow like a boss, has a nice deep sound, and came with all the bells and whistles for the SLE! In June 2012 I bought a million color LED under body lighting kit from ledglow.com. Every time I've driven at night since then I have a smile on my face. It has 120K miles on it and 11 years of aging. It worries my parents that next year I'll be driving it an hour and a half to college. (I'm a freshman now, but can't take my car per the schools' policies). I love the car and will have trouble finding something so nice to drive. I have taken care of it, and it has taken care of me in return. All head/tail lights are stock, no window tinting, no wrecks, Some issues it has currently:

Oil Pressure Sensor (I found instructions on here and will attempt to fix myself in the near future)
Fuel Gauge has the occasional mind of it's own.
1 tire was recently replaced due to blow out and the new one holds air perfectly, the other 3 need filled up every couple weeks
Occasional rough start (not sure why)
Occasional rough shift (possibly due to shifting into drive while still rolling backwards or vise-versa)


Recent fixes include:
New rear shocks, brakes, rotors


Thing's I would like to do/know:
Best methods of keeping engine clean and healthy
High intensity fog lights
Installing light kill switch (like for stealth mode )

If anyone has any thoughts about my car or helpful hints feel free to contact me. Since I just signed up I'll be looking around on here for answers myself too!


2003 Bonneville SLE 120K

Welcome from a fellow 2003 SLE owner/college kid.

Fuel gauge fix is similarly easy to the oil pressure switch. There's a video guide on YouTube if you look up fuel sender replacement.
The rough start could be a number of things. What exactly happens?
Rough shifting could be cured by a shift kit, relatively easy install if you know your way around a car.

There's a maintenance list along with a whole bunch of other goodies up in Techinfo.
You could just put HIDs in your fog lights but the glare would be annoying and dangerous to other drivers. You could projector retrofit the fog lights as a couple members have on here.
Not sure on the kill switch.. It's something rather annoying about the 2000+ generation of Bonnevilles... XD
