    Engine shaking while started up.

    To this morning I went to turn in my car and at first it didn't want to turn on so I kept trying and then it did but it would stall. Then it would stay on but the rpms were so unstable and it was shaking. Any ideas? I didn't have time to check anything cause I was headed for work.

    Spark plug wires?
    Just a guess...

          Yeah I was thinking it would be a vacuum leak but I started with checking the spark plugs and they were pretty burned already so I will be replacing them tomorrow. What would be the best way to check for leaks?

            Smoke test is the only reliable way to check for all vacuum leaks.

              soooo correct, black and slightly wet spark plugs are a clear result of fuel problem.
              probably defected pump, clogged filter or FPR

                How would I be able to do that at home since I don't have a smoke machine or anything of that sort?
