Alright, ill look into an injector cleaning, thanks again for the help

the problem went away for a while and now its back, im getting sparks between the number 4 cylinder plug wire and the coil, i pulled the wire and the plug on the coil is corroded, is that a coil problem or a wire problem? i cleaned both and the sparks are still there.

new plug wires fixed the problem, the spark plugs looked fine so ill leave em till 100k
