Asked by Dec 05, 2011 at 07:59 PM about the 1984 Nissan 300ZX

Question type: Maintenance & Repair

i have a 1984 50th anniversary nissan 300zx. i swapped the engine to a 1989 turbo, since then my car turns on and dies out. When i plug in the air mass flow sensor plug, the car stays on, but cannot drive over 35 mph.

so just for shits i looked up the parts for the air mass sensor between the 2 different motors. they are different parts, so if you are still using the na sensor you may need to upgrade to the turbo sensor. that may just be the problem right there. i don't believe the car would run without the sensor plugged in anyways

Make sure your mass airflow is facing the right way

Unplug your oxygen sensor and turn the car back on. If it's normal but you can smell it running very rich, you have bad wire. Replace the O2 sensor. It's cheap and easy to get to, but might be difficult to get out.
