Ok i did the spark plugs all but two for now because on the right side of the engine the back two are a lil hard to get to and its cold so they will have to wait and i also did the oil filter and new oil but it still has a rough idle at start up and almost stalls, I have a small link on my fuel line it drips a drop like every sec while the engine is running will that have anything to do with my idle?

this is on my blazer

Where is the fuel leak? Internal to the plenum?

 

its behind the driver wheel under the door

 

you probably just need a tune up
