Ill start from the beginning. One week after I pulled my Z outta storage one of my rear axle's come loose and cut a gash in my gas tank. I got a new halfshaft, new gas tank, and all installed and running again. To date, about 5 weeks since I turned the car on again, I have not had any fuel leaks. The problem is however, that my car seems to be running rich. Anything below 3000 RPM's and it seems to bog down, especially if I shift early. After about 3000 RPM's the VVL kicks in and it seems fine. First off, I plan on going through the 6 P's here soon, hopefully tomorrow, but as for a rich mixture I just had a few questions. The first place Ill probably look is the CAS. Plugs should be good, I replaced them last summer. My current thought is that possibly my fuel dampener and regulator may need replacing. Could a bad FPR or Dampener cause a rich mixture like this? I know they both have around 60K miles on em. Secondly, is there anything that could be related to my fuel tank changeover that might be causing the problem? Thanks for the help. Justis
