713,000 miles on this one, and the check engine light just came on. It happens. Get the repair done first, then give us a call and we'll help make clearing the code and passing your Clean Truck Check easier on you. Free retest if you need it.
We come to your yard, so you don't burn $8 diesel. A 30-mile round trip to a test station runs about $40 in fuel plus driver time, so the mobile test comes out cheaper.
Mobile prices: OBD $75 · second truck $37.50 · OVI $199 · second OVI $99.50.
Second test of the year coming up? Call or text (628) 999-3912 or book at norcalcarbmobile.com
