Spark plug wires? Reply #15 – March 17, 2015, 12:22:50 AM Hey again everyone!I've got another question. I noticed yesterday and today that the Cougar has a rough idle, where you feel sort of a rumble. It still has the pep it has had since I changed the plugs (still have the original plug wires on it). I'm not sure why it's doing this. I noticed yesterday when I put it in reverse to back it out of the car port... it acted like it wanted to hesitate. It's still sharply responsive when you hit the gas a little, but the rumbling I feel and the hesitation it gave when I put it in reverse... does anyone have any suggestions as to what it could be?Thanks in advance! Everyone here is awesome!Tommy Quote Selected

Reply #19 – March 17, 2015, 08:26:51 PM If your car hasa functioning check engine light, you can just sit in your chair after inserting the paperclip.usually i record the codes with my phone to make sure i don't miss anything.if not, you'll need either a test light, a buttstuffog volt meter, or a 12v buzzer.
