Hey everyone. Been on this forum for months enjoying all the free info. I did some reading on the N249 delete & figured I’d give it a try while I was replacing my injector rings: BIG mistake. If it ain’t broke, don’t fix it as they say. The issue is, when the car cold starts, everything is perfect. The intake is loud, I can hear the air rushing through, the SAI sounds to be doing it’s job, & the idle is smooth around 1200-1400. No biggie. But after 30 seconds (I guess when the SAI has done it’s job) the idle drops to around 8 and is unstable T-T I have the hose from the intake mani going str8 to the DV. Same with the FPR hose on the second nipple under intake mani. The N75 is on correctly & I tried multiple combinations of T fitting the FPR to the SAI nipple next to, to the N112, nothing did the trick. The injectors are in very snug & aren’t leaking but my guess is maybe the rings are too big? i ordered a pack off of ebay with the correct part number but I did notice they were pretty thick. I read up on another forum stating the diff sizes and to only buy oem rings. But even if they rings we too big, would that really cause the car to idle low like that after the SAI duration ends? My second guess is that the coil pack at the top got messed up while I was removing the black reservoir box but I tested those bu removing one each & it ran worse. So not that. I have no idea what I botched up T-T I just wish I had never did that pointless delete. Everything was running perfectly fine before that. Does anybody have any ideas as to whats going on?
