TOMMYZ

Thanks for all the help. lol

BTW the replacement was a dad gum bad Mass Air Flow Sensor

Please help. My Z was in the shop 6 months and had $900 bill. Still did not run right. It has been parked 4 years. Replacing connectors little by little but still same problem.
If I unplug the MAF sensor the engine cranks immediately but can't drive it. Then when it gets warm I can plug in the air flow sensor and drive off.
Any ideas?
I just changed the cylinder head temp sensor $375. The MAF is a remanufactured Nissan part but had just been replaced. Never really ran good though but hard to believe it's bad. $200 to replace it again. I'm going to try to trace sensor wiring back to ECU. Any other ideas?
