There are a number of things that can cause misfires or hesitation, but the basic items are injectors, fuel pressure, spark plugs, and vacuum leaks.

So, I will attach all this info here, but we should start with pulling the plugs and inspecting them.

I will attach a chart that will help tell us if they are an issue.

Please pull the plugs and see what they look like. If they are okay then run through the rest of this info and we can go from there.

Thanks

Changed the plugs/air filter/etc. Worked wonders! The back plugs were tough to get out/in but all in all a satisfying job. Thanks so much for your help.
