do they still have to pull out the ecu.. caus if they do,, just do it yourself.. turn the screw wait 2 sec, turn it back... look at the led on the dash.. ur check engine light will b blinking,, record number of slow blinks and fast blinks... then when ur satisfied (they will repeat), turn the screw again,, wait 2,, then turn it back to its origianl possition... and its cleared.. and won't come on if u fixed the prob... and will if u didn't :-D..
