Spark plug wires?

Reply #15
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

Run codes and do a base idle reset.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

If I had a code scanner, I would, but unfortunately, I don't.

Do you have a paper clip? If so you can pull the codes.

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.
