2007 Chevrolet Silverado 2500 HD Classic LS 6.6L MIL Lamp on, Limp Mode
This truck throws a P0087 code and goes into limp mode, restricted to 40 MPH when the customer is hauling heavy loads in hot weather only. All winter long it was fine, it only fails on 75+ days after miles of driving. Balancing rates are Cyl 1 -3.2, Cyl 2 +1.3...
