Why does my Gmc still show bad timing chain after the chain has been replaced?
So everyone knows the GMC timing chain issue.
Well I replaced my timing chain. And it still throws
the same codes. Misfire in cylinders 1,3,5. Help!
What are the codes?
P0193,P0301,P0303,P0305 Changing injectors next.
Here’s the update. Timing chain was replaced Fuel injectors replaced Spark plugs replaced Cam sensor replaced Crankshaft sensor replaced Then it gave new code of p0008 Ran alternate ground for two ground wires with no change. Other than pcm replacement I’m stuck.
any updates, I'm having the same issue here.
