I have a 2000 Taurus Duratech, 6 cyl, 3litre w/ dual overhead cam, 24 valve. Car has apprx. 99,000 miles. Car runs rough, misses after rain. I’ve replaced all 6 coil paks, new alternator, plugs, wires. Still missing. Will dry gas help or is this just a Lemon?
I doubt if it is water in the gas, but it might be worth a try. It is not expensive.
Is there a check engine light that’s on? Is so, get the code(s) scanned and report back.
If not, after all you’ve done already, I’d suspect a fuel injector issue.
