CTSvRolledOUT

Alright I got a 2007 Cadillac CTS-V with Prc stage 2 Ls6 style heads w/ dual spring &titanium retainers, Comp cam 232/234 112 lsa cam,Powerbond underdrive pulley,Fast Ls 92mm Intake ported by jeremy formata in Fl to a 94mm,Lingenfelter air intake,Ls7 clutch and flywheel,Lingenfelter short throw shifter,BMR fabrication bushing for the anti wheel hop kit & Pinion Bracket,(which has not done **** for the car!!),1/7/8 Kooks long tube headers,Magnaflow Cat-back exhaust,Drilled and slotted rotors W/ ceramic brake pads,CCW wheels with dunlop tires..

My problem is this... If i am driving at a constant speed the car wants to lug and it seems like its starving for fuel. and now the check engine light has came on in the car. I am wondering if it could be a few different things?? I'm going tomorrow to get them to run the code and see what it is throwing!

Could it be..

Plugs?
Fuel Pump?
Fuel Filter?

you tell me???

I have sat at a red light twice now and the car drop from its idle and almost die.

Not to mention I get pissed everytime i'm in the car, having to listen to the POS rear diff clank and the damn thing wheel hops so bad!!!

Sorry if this post is a little fuzzy, I am furious right now I just got back home from a ride in the damn car!!!

Thanks for everyone's help in advance..

1- Buy some axles
2- could be any of the things you listed
3- sounds mainly like a tuning issue to me, did it run good for a while and just start doing it?

O2 sensor bad? Or maybe crank sensor? Let us know when you run the codes..

+1 could be anything but o2 sounds about right

I would say o2 as well, but it possibly could be the maf as well

I was having the same issue a few months back as well.. the rpms would flutter during normal driving and when I would come to a stop the rpms would drop and almost stall out my car. Then it got a little worse and actually stall out at a light. For me it turned out to be my crank sensor.

Have you let it idle in the driveway and the rpm's drop? Do the fans kick on and off?
