Delete this - I figured it out

Recently my 03 cobra has been feeling off, a little sluggish, harder to start and when im cruising in 1st of 2nd gear(Stop sign to stop sign), it will occasionally miss and ill feel the car kind of..lurch. I did a small data log just to get an idea and im mostly clueless at what im looking...

Debating on selling my cobra to purchase a lower mileage cobra, though i'm at a loss on what it may be worth, that's where you come in. What would you consider a reasonable price with the specs below? 120K miles 2.3L Whipple 3.000" pulley installed also have a 3.500" pulley. Accufab TB K&N...

Did a short idle/rev data log, and i'm concerned with what i see. Short term showing bank 1 max is 1.19 and bank 2 is max at 1.20, i've been told anything over 5% is bad...so at 20% im down right worried. Am i understanding that correctly? or should i not be worried? Car has dual fuel pumps...

Does anyone happen to know where i can buy a trans mount for an 03-04 cobra? I cannot find them anywhere, i can find t56 mounts for chevys, but no luck on the cobras. If anyone has a new one, i'll buy that.

I just got this car, i know very little about it, it has the whipple 2.3, iridium plugs (brand unknown), but when i did a 4th gear pull on the highway, at about 90mph the car backfired rapidly (about 6 times), and a plume of black smoke (i assume unburn fuel) was left in my trail, my battery and...

Thanks for coming! I'm in need of a little help. I purchased an 03 cobra, but whenever i go to release the clutch in any gear, the car shakes, a LOT. It has a Fidanza Flywheel and a Mcleod Street Pro Clutch. Now, that clutch is rated for 350hp, and im sitting at about 600. Wondering if maybe...
