Bad Idle

[esahuque]

To start off, I searched that's where i got most of my info from.

Car was running great. Started it up one day and had a bad idle. So i changed spark plugs, wires, cap and rotor, on changepulled the iacv and cleaned it, no changeBought a new (used) iacv and installed it with a new gasket, no change. resautered the connections to the maf, O2 and my SAFC,cleaned and tested the maf with maf cleaner,Did a boost leak test and sprayed carb cleaner all around the intake (no leaks found)tested temp sensor, test ground to chasse, tested tps.Found that the first injector was a little loose so i pulled the fuel rail and tested to see if i had a leaky injector, nope!!!!!pulled the injector out and changed all the o-rings (just in case) NO CHANGE!!!!

here's a little vid of it running. It seems to lean out and the RPM's fluxuate up and down when it happeds. It does it when it cold or hot.

Injector misfiring? I have no idea man. That's kinda buggered up.

well its not my BOV. it may have been leaking but that's not whats causing it to idle like that. took it off and plugged the hole and just let it idle (not drive) like that and still no change. So I took a stethoscope and pulled the tip off where its just a hose and put it all around my intake. Sounds like i may have found that the PVC system is leaking. when I put the hose in i could hear a loud hissing noise coming from that row of hoses that run across the back of the intake. Once AGIAN I'm go to pull the intake off and replace all the hoses on it. EGR system has been removed so i shouldn't have to many hoses to replace
