Don't know whats wrong with my car please help

Postby Applewhite » Sun Oct 04, 2015 10:21 pm

I'm new to the site sorry if this is in wrong spot but i just bought a 300zx and when it dies when its in neutral at idle but in gear at idle its fine. only died when i come to a complete stop in neutral, my check engine light is flashing the throttle position sensor and I'm not sure if that could fix it or not its a 60$ part I'm going to buy when i get the cash but I'm just curious. if anyone knows please comment or message me thanks

If you have a 1996, go get the ECU codes checked. It should give you an idea where to go better than pre 1995. OBDII is a very good system that better directs what is needed to be fixed, but it also follows the same line of checking connectors, and anything else that connects before it.

If you state the TPS is coming up, check the wirirng and connectors first, but if all looks good, more than likely the TPS has failed or has a dead spot. There is ways to check if the TPS is functioning correctly, Im not sure if its the same as pre 1995. On the main page there is "everything you need to know about the Z32", read through that. It also has a FSM that you can look through.

BTW, welcome.

One thing to also let us know, is it a 5 speed or a Auto? Do you have any mods? Is the intake stock or do you have a pop charger?

As mentioned use the OSM in the sticky for testing the TPS, and IIRC your issue may also be an issue with other things so be ready to test a lot of harness connections for corrosion and continuity.
Oh, and as also mentioned you are OBD2 so you can get more input from your ECU codes.
Good Luck!

This is probably not the issue, but it never hurts to check your MAF sensor for any obstruction. I got a leaf stuck in mine, messed up the air flow reading, killed engine. But, car died in neutral and would die in gear if I wasn't on the gas. It also after awhile had trouble starting as it leaf got stuck worse and obstructed MAF more.

Very easy to check, it's along the air intake and probably just bolted in by two screws (mine on my sentra are philips)

Most likely the iacv issue, take it off, clean it up, costs nothing to try.
