I just removed the smog control off my c2500 now I have a check engine light on and can't find the aldl to check the codes. where do I need to look? It also is idling high and hesitant to go when first start out but runs fine when under power since smog control system was removed.
I just removed the smog control and now the check engine light is on. I'm having trouble finding the aldl to check the codes to figure out why the check engine light is on. Where should it be?
