HI there,

If the engine won't rev past 3000 rpms, then it's likely the problem is with the mass air flow sensor. These sometimes work fine until they get hot, then stop reporting accurate data to the computer. This causes a huge issue with the fuel mixture and when the computer can't get the mixture right, it turns the fuel off. This normally happens at about 2500-3000 rpms
