Yea Tblake, its the 3.1 The Euro edition just had the same Suspension package as the Z34, but with 15 in rimcs instead of the 16. they look exactly the same though.
One thing also, thre old owner of the car was my neighbor and at 120k miles it had a major tuneup done, she said shes not sure if the PCV ever got replaced. and im wondering if that can do it also? maybe cause some kind of weird thing. i know that it can cause high idle if clogged. but i will check into getting wires, and maybe even some new plugs. I just hate doing the rear plugs and wires... just gotta rock that engine forward for an extra 4 inches hahaha.
the Fuel pressure is fine, it was like 40 psi i think my brother said. im not sure
