Mass Air Flow Cleaning: Cost Under $20, $7 if you have the tool.
My 2001 "s" 67k mile was starting real ruff and had thrown a couple codes. White smoke was also evident when first starting. This simple 10 minute job fixed all of the the above problems.
Codes:
1.)p1133= oxygen sensor, adaptation, lower load bank two above limit.
2.)p1126=o2 sensng range 1 cyl 4-6
Difficulty: 1.5 out of 10 (pretty basic)
I followed the directions below but found a few shortcuts.

Tools:
1.) t-20 tamper proof torx bit. (I used a bit that fit in my screwdriver rachet thingy) tamperproof= a frickin hole in the bottom of the bit.
2.) Can of MAF sensor cleaner(autozone $7.00)
Procedure:
1.) disconnect batter
2.) open engine compartment
3.) next to your air filter you will see the Maf, unscrew the two screws(t-20 TP)
4.) REmove the MAF sensor( I didn't unhook any wires)
5.) Place a couple paper towels on you engine and spray off the sensor, make sure to squirt it up in the hooked end and the paperclip looking thing at the top.
6.) let dry (5 minutes)
7.) put back together and connect your battery.
Thats it. Simple 5 to 10 minute job and hardly any mess.
If you see oil or sludge on your sensor you probably have another problem up stream. Mine looked clean but after cleaning it, all my gremlins went away.
