Ok, new to the 03 cobra stuff, heres what I did.
I installed a new sct maf and 55 lb injectors, a accufab plenum, mac longtubes with 50 series flowmasters and a tub k-member. the car has a sct xcal 2 tuner and was running great before the install. After I put everything on I started it up and it wont idle down, start about 2500 and then goes up to 3500 and jumps of what sounds like the rev limiter, so after that I went and took the injectors and mass air off and put the stock stuff back in, still wont idle its still starts at 2500 and works its way up to 3500 then just sits there. I unplugged the mass air and then it idles down to 500 and up to 1000 and back and forth.
No codes are showing on the tuner or my engine scanner.
Not sure what to do, Help me out if you can.
thanks
bob
