Test the sensor before you go out and buy one, it could just be a bad connection. The test procedure is in the manual that I linked. The EFI components are somewhat pricey. Have you cleaned all of your electrical connections? Especially the fuel injection related ones? I don't like to throw parts at a problem. Buying new parts to replace functioning part gets rather costly.

Fordlover,

Here's a great website, especially for the fuel injected S30's:

CLICK ON "NEW TO Z?", in the center of the page. the Z Tech Tips is by far the most comprehensive, useful, easily read, small volume that had kept my 280Z driving down the road!

Scroll down 2/3, and take a really good look at the section labelled Tune the Car If you follow this step by step, you will surely find the solution to what's ailing your Z.

Personally, because you say it dies when you step on the throttle, I would lean towards a vacuum leak. Half of this system is based on vacuum, and there are a lot of vacuum lines. If your 75 has a vacuum water **** on the inside of the firewall right up next to the heater core on the passenger side, you should ckeck those lines...they are probably craked because nobody even thinks of them. Secondly, really check the Z Tech Tips for AFM and TPS systems. Bad throttle response can sometimes mean someone messed with the TPS or AFM.

A lean condition usually backfires through the AFM. You can hear it pop when you step on the throttle. Leaking vacuum lines usually cause a lean condition in these cars.

How do your plugs look? You can tell a lot from what the plugs are saying to you.

Hope this helps, let us know what you found.
