Check the system, use the tools.......KOEO/KOER self-tests don't guess, it could be more expensive to keep on throwing parts at the problem. My 2ยข.

RE: so sonfused!!!!
sigh.... everyone always says to check the codes. which, in itself, is not bad advice.
the problem is, 75% of the codes you MIGHT receive are caused by something completely different, thus leading to replaced parts that didn't need it.
verify correct operation of different non-electronically controlled parts FIRST. for instance, in this case. i'm suspecting your gas tank baffle has come loose. mine did, and created symtoms similar to what you have vaguely described, with a gas smell as well.
i suspect that you only think its running rich, and havn't actually verified this, as running rich and starving for gas provide almost identical symptoms.
