CHeck to make sure that your VAF is connected properly. The VAF is located on the intake tubing, and there should be a wire harness connected to it. Make sure that the wiring harness is firmly plugged. Also check the intake for any holes or places where air can squeeze in without the VAF knowing. Basically, the VAF measures how much air is coming into the intake, so any excess air coming in will mess up the process. Also check all your Vaccum tubes.
