new parts bad idel

[scherger_16]

so i have s13 sr20det installed a t28 555cc tomie injectors greddy front mount 300zx maf installed and tuned and the car wants to die out at idle so i set it to 1500 rpm otherwise it will stall out when i come to a light and when i start my car and just let it idle i does what it wants i cleaned my idle air control valve that did nothing the only thing that i think could possibly change it is the hose going to the intake pipe to the valve cover now has just a filter on the on side then goes back to that factory catchcan

First, punctuation is your friend.Second, what tune did you get? Were the parts bought new or used?

First thing I would do is check for vacuum leaks. After that, case like this trial and error is going to be your best bet. Check the injector o-rings and make sure you didn't chop one up when you were installing it. See if you can swap the MAF for a known good one (find a friend) and see if you have a bum MAF. Make sure you wired your MAF correctly. Etc etc etc

s*** i knew i should have payed attention is school haha. anyways i know the injectors were installed good the maf was off a perfict running car. the city i live in a cant think of anyone else who has a 300zx maf to try. whats the best and easyest way to cheak for vacume leaks. and all parts are brand new out oif the box. i have removed the vacume canister also but pluged off all the proper vacume lines in the intake but i dont think thats my problem.
