2010 GMC Acadia - 228000 miles - automatic transmission, V6, SLT
I had my timing chain replaced at the dealership. They were unable to start the vehicle afterwards, so they change the spark plugs as well.
Picked up my vehicle the next morning, and on my way home the check engine light came on. Error codes are for cylinders 1,3,5 misfire detect (P0300, P0301, P0303, P0305), engine position system performance bank 1 (P0008), camshaft position correlation bank 1 (P0016), Sensor A and B (P0016, P0017), and Camshaft position slow response bank 1 (P000A).
Prior to the timing chain replacement I was getting a P0017 sensor code but never had any codes for Bank 1 misfire.
Could this be the result of the mechanic having the timing chain off by a link or two?
The dealership obviously screwed up. Take it back for them to fix and say you want their most experienced guy on it.
