Your car is approaching 13 years of age. If you've not replaced the 02 sensors, I'm betting they're due. This might fix your problem.
BTW, I was not experiencing CE lights or any performance issues and I replaced my 02 sensors because I figured they needed replacement after 85k miles. The difference in power and performance was very noticeable. It was worth the $450 I spent on four new ones (bought mine from OxygenSensors.com). They've come down in price a lot since then...

Will exchange of the two rear sensors do any difference to performance if they are worn out? I was under the impression that they only did some follow up on the efficiency in the forward cats and made no change the A/F ratio. Would be interesting to know before I pull the trigger on a new set of O2 sensors.
