Car misses... water in gas possibly?

[Jtownrook99firebird]

My car's been miss'n some... it was really bad and I replaced the plugs and wires... still just as bad... I ran som Heet in it and it got better and ran another bottle... bout the same.. still misses slighty tho but not enough 2 throw a code... since the heet worked I'm thinking it has 2 be fuel related~prolly water in the gas... so I guess I could either replace the filter.. see how that goes.. then get tha tank and lines flushed if I don't see a difference...?

have you checked:

o2 sensors
fuel pump

if you think about it, the 3 things that cause a cylender to fire is gas, oxygen, and a spark. after that then maybe the battery, generator, wires, etc.
