Still the same car. Just now getting back to it because somebody was interested in it. I used Bars Head Gasket Sealer on it and that cured the occasional smoking out the tail pipe problem, but it's still bogging down like it's running out of fuel sometimes. I thought maybe the gas gauge wasn't working, so I put some gas in it, but that didn't help. I'm going to put a fuel filter on today and run some Seafoam through it. I've also heard about an electrical glitch on Contours that I may have. I forgot exactly what part he said goes bad on Contours sometimes. Was it the wiring harness? I'm hearing more crackling from the catalytic converter than usual like it's getting too hot. I'm wondering if the cat is clogged up. Any ideas are appreciated!
