The car runs great before the engine warms up, but after that it runs rough at any speed or rpm range, in gear, but it revs up with no hesatation or skip in nuetral or park. But when a load is on the motor it starts skipping erratically. I have changed coils, sparkplugs, cat con, O2 sensors, cam-crank-knock-temp-ect-sensors but no change switched injectors around, smoked the vacum lines what am I missing it has me puzzled, the ECM-ECU-PCM has been checked its fine also. PLEASE HELP ME IM STUMPED oh yea it has thrown a 01300-01400 code out there to which is a unknown code in any manual or guide I have access to?
