I have a 91 300z non-turbo and for the past few months I've been having problems with the engine cutting out. It first started last summer when I filled the tank with 91 octane and I thought it was bad gas. They tested the fuel pressure and it was correct. It will start sputtering and sometimes die completely and will not start for a few minutes. After only a couple of minutes it will start again but either dies or will go at very low rpms.

 

Welcome to ZDriver.

84-89 300zx's = Z31
90-96 300zx's = Z32

Moved thread to Z32 section.

 

welcome

for future help please try to use the search feature it can be handy

now for your lil prob.
i will almost guarentee its your maf sensor plug
go through every connector and clean/ repair them.
and if you want (i do) put some dieelectric grease on them.
do this and let us know what happens

 

Or you may have a series one PTU which can cause problems as they warm up.

 

Better yet, search. I recall no less than two threads about this EXACT problem... both with several suggestions and ending with the problem being resolved.

 

Hi, thanks for the responses. I did as suggested and removed, cleaned and put back together the MAF Sensor and the problem went away. Many thanks for your help. In the future I'll make sure to search the existing threads.

Thanks,
Chris
