Message	I'm getting bucking right around 4k rpms. I believe its more rpm related then boost related, because in 1st gear I'm barely hitting 1psi when it starts bucking. Shift to second I can get about 5psi at 4k then starts bucking. In Neutral rev up and it won't really rev above 4-4.5k... Did so far... 1. Brand new TPS 2. Cleaned MAF thermasistors 3. Has updated PTU 4. New spark plugs Need some places to start on this bucking issue. Next wierd thing that happened after having the battery undone for a few days. After I shut off the car I would hear a noise coming from the rear of the car. Sounds like something is powering on, then off. The Hicas light is on while driving the car. So I think its either the hicas or the fuel pump turning off on on when the car is off. Its wierd... Thanks for any info, I'm new to Z's and been searching this site for a straight week on this bucking issue....
