just replaced the injectors in my car. 13b na s4. and it started but wont idle on its own and backfired a nice big flame as soon as i started to rev to 3-4000 rpm. then shut off. then started no idle still then killed itself now wont start again. im about to say whatever and junk it. i really need help

 

Did you use all new gaskets on the manifold? Old ones will cause vacuum leaks. Fuel injector grommets can also cause big vacuum leaks that will stall the engine.

 

+1 for vacuum leak caused by the installation. The injector seals are best held on by some grease as you put the injectors in or else they will go out of place and cause a vacuum leak.

 

i know im dumb for this but i reused everything. but the injectors that came with it as replacements had the gromets and everything so i reused those on them too. but the injectors are really bad i think. i need brand new ones. i did it ghetto cuz im trading it soon for another rx7.
