if you say its running rich just adjust the carburetor so that it doesnt combine as much fuel in the cylinder per stroke and it should help a little bit, just remember that it might sound a bit different and have increased or lowered revs, dont change it too much but you should be able to see a difference, if not id just ask a mechanic for their opinion
im sorry but you got to be kidding about the carb right
Try the o2 sensor, no code doesn't mean it is working properly, it just means that it is still in spec.
yea i have changed the o2's, cat, egr, throttle body, tps, im about to change the fuel regulator, n take out the charcoal canister
you can also lean the mix with the regulator as well to reduce the dumping. Another thing that could do the trick is snatch mass airflow sensor from a 96-99 chrysler sebring Which is a v-6 and swap out your for that. The ECU will notice a different (larger) volume of air and go into a drive cycle mode. Drive the car around for this reason so the ECU can make the natural adjustment to the MAP and that will allow you to burn cleaner and grab more power at the same time. I have done this to my 96 Eclipse GSX 2.0 4G63.
