| i have a bone stock ka24de in my s13 (it is a s14 ka) runs like a top perfect cold start up and take off. egr removed via block off plate. only issue i have is the car after getting up to operating temp, and after driving down the road at 55 mph when you put it into neutral the car dips down to about 2-300 rpm and then idles around 600(kinda low) then when you take off from the light it "hesitates" from 1500-2000rpm ever so slightly, not bad just anoying as all hell. any ideas? | |

| when is the last time you did a basic tuneup? with the limited info it prolly has a junk injector. typically #3 goes bad. | |

| everything is new, plugs are new and look great, never smokes. cleaned maf, checked for vacum leaks. do you think it has anything to do with the "aiv"? (that thing that hooks to the exhaust manifold?) | |

| i doubt it. with it running after warmup unclip each injector plug one by one. if the idle drops that one is fine but if the idle stays the same that is your problem. that is how i bought one of my 240s. altima injectors work also. | |

| If its not a junk injector. Try testing the IACV and maf. Sounds more like an IACV problem than an injector, but you never know. | |

| I'll have to take a good look at those things when I get some time I realy apreciate the help. It took no time at all to get some help here! Compared to other places that didn't even respond to my question I apreciate the hospitality guys! Hopefully I can lend a hand sometime myself! Still learning these damn nissans.. Been a Honda guy my whole life.. They just bore me now | |

| If your iacv test out fine, then start looking for vacuum leaks by using some carb cleaner. | |

| might wanna also check the seconardy air regulator, there is a line that goes threw the intake manifold. If you pinch it and the engine speed drops it should be tested/cleaned/replaaced. its also knows as IACV- air regulator FSM | |
