Re: check engine light came on
Could be a number of things. I had the same problem and cleaned my MAF
with a $3.49 can of electrical contact cleaner (even though the
manufactuer "forbids" this practice) and haven't had a problem since.
The following web site explains the code a little better....if the
suggestion be to replace the MAF, ask about cleaning it instead -- it's
nice to do the "forbidden" everyonce in a while....
