Guys, Upon a light cruise, all of a sudden I get codes 33 or 34 and the car strats sputtering and bucking then it goes away. On the scanner it appears that when this failure happens the MAF values lock in place, sometimes high sometimes low. I am trying to check the wiring from the computer to the MAF sensor, changing the MAF (swapped out with an old one, no change / have a new one on the way). Already checked the relay's. Can you guys make any other sugestions on poossible solutions? Thanks!

 

those codes reference the MAP not MAF
