rpms won't hold.
I did a search but found nothing to help, so here is my question.
I have 1 1995 acura integra gsr w/Jrsc. when ever I try and hold a rpm below vtec it has a short blip(drop of 300rpms) every other second but it idles fine. Now the strange think about this is that if I rev it up past vtec it won't drop at all. The fuel pressure drops 5 psi every blip.
Any ideas?
I have a built motor and alot of other mods including the fuel system but It just started doing this after I had the car dynoed.

what do you use for fuel management? has it been tuned? what did you change when on the dyno?
who installed the fuel pump? did they do a wiring upgrade? how do you know that its a fuel problem?
my LS has random blips between 800-3000 rpms.. never higher.. but that is because the boot on one of my plug wires is shot and is arcing to the head (hope it won't hurt anything)
just make sure its not a simple ignition problem

Re: (MusclecarGuyhasHonda)
I am running just upgraded fuel pump fuel rail,fmu and fpr no managment system. The only thing I can think of that was changed when it was dynoyed was the timing but I have already had that all done. My fuel pump was installed two years ago and I have never had a problem before. As for a fuel problem I don't know if it is.
It does not bother me that much cause I lowered my boost back to 8psi and put the stock injectors back in so I don't notice it at all unless I rev the car up to hold the rpms, but I want to put the 10psi pulley back on and if I do that I will have to put the bigger injectors in. With the bigger injectors in the problem is very noticable while trying to drive on the freeway at a constant speed.
and thats my rant.
