i had it smog tested and it faild only the check engine system because I recently had my car jumped started so he said i need to drive 30-40 miles to reset it???????
its a 1998 blazer if I un-hook the battery for a few minutes will that reset the computer so I can pass the smog test for registration everything else passed but that.
no my Check engine light was not on when i did the smog test for vehicle registration
 
Was your check engine light on when you went for the test? If it was not and you failed,its cause your monitors are not ready.Any time you have a dead battery or disconnect it, the computer monitors reset.You have to do some normal driving for a bit to get the monitors ready again.No way around it.Best bet is drive it a few days and go to a mechanic or someone with a scanner so they can see if your monitors are up so you can get your emissions test done.If the monitors are up and your check engine light is off,you will pass..
 
you have to complete a drive cycle, you wont know when that happens but try to drive it in the city and on the HWY and it should do it within the 30-40 miles
