Buy some MAF cleaner and clean MAF sensor, if problem persists, then you will have to get car scanned in live data mode to see if MAF or TPS is problem.

TPS sends signal to PCM telling it % of throttle opening, PCM compares this to MAF reading. If values are out of range to each other you will get this correlation error.
