I got a 97 cobra she'll start up but won't idle. She just dies. I replaced the mass air but that didn't fix it. when I keep it alive it run really rich. Any suggestions? Oh and it pops when I fether it.

 

I had the same problem with mine... a '97 also... I think that that is just a coincidence having more to do with the miles than anything else... I saw this site on another posting and found it very helpful. Check it out, it may be the fix (and relatively easy) for your problem.
