I just had my check engine light pop up last night. I already have had 1 injector replaced about 1 1/2 ago. The dealer had my truck for 4 days tbey put dye in the coolant to see if it was leaking into a cylinder.
Then they finally after the 3rd day saying it was a bad injector. Now im sure I will have go though the same process again.
I dont know why they wouldnt replace all of them when this happens if they know its a recurring problem. Maybe they need to do a recall?
