So i'm trying to clean up my engine compartment last weekend and while putting the airfilter back on I bump the distributor, and it moves. I tried to put it back in place, but who knows how far I moved it. Now when the truck is cold it has NO power, and backfires out of the carb. I have had to pull over and let people pass. I know diznick about motors, but after reading a bunch of posts it seems like maybe I f'd up my timing. Is this possible? is it that easy to change my timing? How do I fix it? Sucks to pay shop rates if it's easy. I would rather buy a $70 tool and do it my self then pay some one $70 to fix it once. So, can some one (in laymans terms) tell me what to buy, and what to do? step by step.
