rough idle and cutting out

[icucnme83]

i have a 99 gsx and i just put a injen intake, greddy hard piping and a rs bov on the car. i have noticed when you stop at a red light or stop sign the car idles real low and almost stalls out but it doesnt stall. i have check for leaks and cant find any. also when i start getting in the rpms like around 5500 6000 not hammering it to the floor board just a slow steady climb it cuts out and starts to jerk alittle till u back off and than when u punch it to the rug its fine but i can feel it loosing boost? need help. is the bov to hard?

1. Are you recirculating the bov?
2. Do a proper boost leak test.

Sounds like TPS might be acting up or you might have a bad injector.

Recirculate that bov and do a proper boost leak test.

For all those thinking of venting your BOV to the atmosphere - read up:

http://www.dsmtuners.com/forums/search.php
Enter "BOV venting" in the keywords field and hit Search. Also try separate searches using "BOV atmosphere", "BOV vent rich", and "venting atmosphere". You'll find plenty of info on this subject that has already been beaten to death. Select the Thread Titles option for better results.

Quick summary: don't vent your BOV to the atmosphere unless you're running a MAFT or standalone engine managament system, or you simply just don't care about your car's performance. A chip and/or S-AFC won't make it work right. If you vent your BOV with the stock MAF and you have stalling or stumbling problems, we don't want to hear about it. You've been warned. The only forum you may ask about venting your BOV (if you don't have an MAFT or standalone) is the Newbie forum.

from what you ar saying it seems to me it could be a bad fuel filte or bad spark plug wires, i had the same problem with my 2g N/T, i replaced the filter and it fixed it for a lil bit then it came back, so i replaced the wires n it hasnt givn me a problem since, but since yours is boosted i dont know if that would be the problem because i dont know much about turbos, but give it a shot cant do no harm by replaceing things that will eventualy need replaced

Definitely agree that you should recirculate your BOV. Also check for vacuum leaks. Did you hook up all the hoses from your old intake to the new one? Recheck all connections to make sure they are tight. Also, having your BOV adjusted too tight would not have any of these symptoms.

Remote possibility: if you are running 17-18 psi you could be triggering fuel cut now due to increased airflow? (not sure about this, just a thought)
