Bought a 1990 300 ZX TT. It has a rough idle so i did the diagnostics check using the box on the passenger side floor board. It gave the failed injector code. So what i was wondering is if anyone can recomend a good injector without breaking the bank and any parts i may want to replace while i have the plenum off.

The search feature is your friend, injectors and such has been covered often over the years...and if after that you have questions, at least the basics have already been covered.

you want the later-style injectors, to better handle ethanol, i don't know if you can get injectors for cheap.

Not cheap just a decent price and something that won't crap out on me anytime soon.

then nismo740cc's, but you'll need an adapter to your older-style fuel rails?

you could actually replace them one at a time, but they will continually fail, one after the other once one goes. might as well replace the lot if you are planning on taking the plenum off.
