Missfireing RB26

[89 GTR R32]

My R32 is missfireing every now and then. Manly when I get down on it a little and come to a cmoplete stop. It does not sound like it is doing it very bad, but enough that I can tell. The guy I purchased it off of said he put brand new coils and all on it and I believe him because the car came with all the old coil packs and other ignition crap. I was maybe thinking that maybe one of the coil packs that he got was just bad from the start, but what do I know. Just asking for any ideas on what you guys think it might be (I don't have any expereance with RBs). Thanks.

what is your misfire like? my car has developed a slight one at part throttle, i mean, when it does it it is a dead miss and i'm kinda wondering if my cas is acting up....

It kind of sputters a little, like it is kind of fluding it self a little.

You are saying that it is sounding like it is mis-firing at idle? Kind of, like, sputtering a little, but only does it like every 10-15 seconds or so? If so, then it is most likely a leaking injector. Very common with older engines. Now, new injector o-rings will not solve this problem. It is the actual injector leaking through the pintle cap. Only solution is to buy new, larger injectors and a Power-FC....
