The MAF was OK, but the throttle body was really dirty, lot of oil and dirt. After a nice clean my Z is running great, and the problem never come back.

Its been 5 days without a problem.

Hope this help someone.

Certain cars (GM) cleaning the throttle body can fix so many poor running conditions. Also this k&n don't help with sticky oil gathering on the throttle bodies, just my opinion as I've seen it numerous times.

Man skimming through this thread makes me so glad I left the industry last year. It's scary out there with shot gunning parts. Not once unless I missed it did I see a residual fuel pressure test done. If they had done that they would have found the pressure not holding. Then cut off the fuel line and see if pressure holds, in your case it wouldn't because it was the injectors leaking. Would have saved them all the trouble of fuel line, ECM, fuel pump guessing. Lucky for them Nissan you don't have to drop the tank to change the pump or even worse corvette saddle tanks (15hrs labor) just to find out your wrong.
