Unfortunately, the ECM will only code when it senses something that it knows is rong. For instance, a vacuum leak that the ECM can't detect can cause such a problem, but the ECM is blissfully ignorant and happy and correcting for the leak...most the time. Time to go back to old school troubleshooting, check for vacuum leaks in the intake system...old school. WD40 sprayed onto/into the nooks n crannys of the intake system. Where exactly you say...check youtube, they've got great vid's on subjects like this.
