Nice guide it's nice when people post step by step with pics, makes it easier to follow
On suggestion: electrical cleaner works better than Alcohol. Cut and past from an earlier post of mine:
Clean the MAF using electrical cleaner, can be bought at radio shack.
"In order to remove oily residues from the MAF, you want a non-polar solvent. A "no residue" electronics cleaner/degreaser will work MUCH better than alcohol, as it will have been compounded to dissolve oils and will therefore contain a non-polar organic solvent. Alcohol just doesn't dissolve oil very well - try cleaning your hands with isopropyl the next time you do a bit of wrenching - it's doesn't work very well. Polar solvents dissolve substances that are water soluble, but do not dissolve oily substances. Non-Polar solvents dissolve oily substances, but do not dissolve water soluble substances. Moderately polar solvents have a tendency to dissolve both types of substances. Petroleum distillates are non-polar, alcohols are moderately polar, and water is polar."
