Here's the problem with the cobra. I put about 50 miles a year on it so maybe it's neglected!!! It starts up perfect and idles and revs fine, but once you start accelerating, it hessitates bad and its impossible to get up to speed. It never stalls though, so the only problem is when accelerating. The only code I got was a fuel pump circuit failure. But since I unhook the battery after I drive it the code hasn't come back. The mass air was cleaned a few weeks ago and the fuel filter, cap, rotor, plugs and wires are about 3 years old. Anyone have any ideas??
