Ok guys i have a problem ive been hiding

[Wang2k]

Ever since the first time I cranked up my car with the sc(at 4 pounds 7 lbs it acts the same) my idle has been like a top fuel dragster. It surges and is very erratic. I have a vid if anyone would like to hear it. Anyway could it be my weapon R intake with HUGE K&N? ive searched and searched on here and cant decide what i think my problem is. any suggestions? all my vacuum lines are connected i have the pvc hooked up, the brake booster hooked up, the line on the top front of the supercharger is going the the vacuum rail, i have a T installed in that line and its going to the bypass actuator, i plugged the one line from the vsv for the acis. the one way check valve is installed in the throttle body line with the mark on the throttle body side. does this sound correct?? any input would be greatly appreciated as i am stumped(unless its my short ram)

also(im just remembering this) i think it might be my oxygen sensors k im done

[Mandarinsolara]

short ram intake and/or a K&N conical filter would never do such a thing
that is the only thing i can assure you of without seeing that vid

put it on streetfire.net or something ... or uh putfile.com ? is that right?

Sounds very much like a vacuum leak. Have a shop hook up a smoke machine to the intake system and see if you can find a leak.

mine was erratic when I first started the car when I got back and sure enough, a couple of miles later, I threw a check engine light corresponding to my O2 sensor. Could be the same thing. Even before I deployed I had the same problem and never threw a code, but it seemed to fix itself. Not this time I guess

i get codes at idle like System too lean, system to rich, egr flow excessive(this one didnt come back on) , o2 sensor slow to respond, etc

[Akfahad]

ooh man, don't know what to tell you. I was just thinking (and hoping) it was just the O2 sensor.

[Wang2k]

i think it is the sensors, they could be really bad as i think they may have 110k on them did you see the vid? noone wants to race me they think im all cammed out and crap

Sure sounds like an air leak to me.. Better double check all your hoses and make sure you're using change #1 of the SC installation instructions.

[Wang2k]

could you please comment on the routing of your vacuum lines? what is this VOT that is supposed to be zip tied to the fuel rails? hmmm???

[Wang2k]

I FOUND IT!!! thanks guys but due to my ignorance i never did anything with the port right under the throttle body thats hard to see, i capped it off and things are alot smoother, i still think i need some o2 sensors. I have switched to a 5.5 lb pulley until i can get an afc. I found a dyno tuning shop(Polk Performance) and hope to get some time in soon(5 runs for 150 with tuning

I'm glad you found the problem. I'm about to comment on the Weapon-R intake that it is working for me. I also changed the filter that came with intake because it's too noisy for me, so I installed the K&N RR-3003 instead. A heat shield for the filter was added too.

Man this looks F*&^% AWESOME!

^^the crazy part is that its all in a minivan!

[jim@foreignaffairs]

Looks outstanding but you better fix that fuel system before you run much boost. I bet it still surprises a lot of people though!
