well at around 1500 rpms and at take off my 2002 Cougar with the 2.5L V6 engine missfires and hesitates.I have only 12k on the plugs and coil pack. And I just recently put better wires on it, still have a low rpm miss, and it started happening after I got gas at this one gas station. And at 3 different times the check engine light flashed for about a minute then went off and no codes are stored whatsoever. Can water in the fuel be causing my missfire?
Could water in the fuel cause a low level missfire? on 2002 Mercury Cougar

the codes are stored but you cannot read it with a code reader. could be an injector issue. i suggest a shop to track down the issue and give you a bid. by driving it the way it is with the missfire, you can damage the cat converter to the point of requiring replacement.
