View Full Version : Newbie with a couple of ?'s

Howdy fellow Cobra owners,
I am now the proud owner of a 98 Cobra with low miles (56k) that seems to be in really good shape and I am happy to be back in a stang after piloting a few sporty sedans for the past few years.

One question I have is regarding how smooth the idle should be?
The cars runs just fine but at idle sometimes, it feels a little lumpy.

Is this normal or something I should look into? I know the motor shouldn't need new plugs at 56k but then again they are 12 years old also.

Any Thoughts?

welcome. It probably wouldn't hurt to change plugs. Where is the idle at, rpm wise?

Looks like it is consistantly idleing @ 850 rpm. Does that sound about right?
