Whenever I get in my car and go it starts to misfire! I already changed my spark plugs (the old ones were screwed), it helped a little bit but it hasn’t fixed the problem. Any ideas???

x2. Pull the new plugs back out and see if one is still really clean like it hasn’t fired at all. I have seen this happen more than a few times. If you park somewhere were it is pitch black ( I mean NO light at all) and pop your hood you will usually be able to see the wires sparking if they are cracked.

How did the old plugs look? could it possibly be over rich, or too lean?
