I have a 96 mustang 3.8 5 speed. Car runs good while driving but misses at idle. The previous owner replaced plugs and wires but didn't solve the problem. CEL light is on, my mechanic pulled the codes and they showed a missfire in cylinder 2 and 3, and the engine is running lean. The cat on bank 2 also showed up and he said that my fuel pump had some sort of code for low voltage. My fuel line is also leaking on the return line right at the flange near where the fuel pump is. The mechanic thinks this may be related to the cat for some reason.

He recommanded trying a compression test to see if its the head gasket or the valves. Are there any suggestions or ideas on what the issue might be? Also where can I find a fuel line? What year would fit my car? My mechanic told me that they are discontinued by ford and no place seems to sell them, eBay and craigslist doesn't have anything but rubber lines. He wants to make one custom but it won't be cheap. So what do I do? Am I screwed?

From the cat throwing a code, and the passenger side bank of cylinders misfiring it sounds like a bad O2 sensor on the passenger side to me. Would help if you supplied the exact codes that the mechanic pulled from the car.
