89 240sx; Help, with my 240sx please

[s13drft89]

Hello,well here it goes, i just changed out my head gasket due to a blwen one, well i put everything back together, and well for some reason i believe there called gormmets, there little donuts under the fuel rail, number four had ripped which caused a fuel leak, i changed all four out brand new ones, well i put everything back together, as then my fourth injector didnt want to work, so i changed it out, and replaced it with another, the car revs much better, but does not idle for nothing, i dont know why, nothing is ripped or broken all injectors are working. Iam stunned and stuck, if any help could be given i would appreciate it, i havent gotten drive this thing in 5 months, thanks

Is it flooding? Is the IACV working and adjusted properly?

It is still possible that one of your injectors is meesed up. It is possible that when you had them out that one of the nozzles got messed up and it isnt spraying right at low pressure. Whenever I change out one injector I go on ahead and change them all. Also check your mas air flow,TPS, and stuff like that.
