No, don`t do that. When you get an engine light, the car computer
goes into a default mode, called "limp home mode". It retards the
timing and does some other things so the car just runs. Your mileage
and performance will suffer.
As someone mentioned, it`s probably the relays. I seem to have to
replace mine every other year, so now I buy two of each at a time.
They`re not that much. You can still buy them at the dealership for
about $12 and $18 each (can`t remember which one costs what). Take 15
minutes to replace. Couple bolts hold them on over by the battery.
Note that after you replace the burnoff relay, it might take a couple
of starts before the code goes away. The burnoff relay clicks on when
the car is shut OFF. I`ve apparently had enough crud on the MAF wire
where it took a couple of burnoff cycles to clean it throughly.

Thanks Guys,,,
I`ll replace those parts. Should I disconnect the battery for a few minutes
to delete the codes aswell?
Thanks
