I have gone through 2 sets of spark plugs in a weeks...what the hell is the problem

 

first off what kind of plugs are you running?
The ecotec engine prefers the plugs that are designed to work with it...

any other background on the car?

how many miles?
what routine maint. have you done? and at what intervals?
what modifications have you done?
have you had the car tuned?
is it throwing any codes? or a check engine light?
