so, on my second run of the day, im about to line up, do a small burn out at about 4k to get the dust off the tires, and take off

it was a nice quick launch, no spn or hop. so then, im getting to the top of first gear, the car studders and hits limp mode....the tach shut off and i had to drive all the way back to the pits.

when i got there the car was running really really rough. i then shut it off, and tried to restart it and it failed shuddering hard four times.

so i left the car to cool, got it some gas then it started up and seemed to run fine, but with a CEL that went away shortly. i grabbed the OBD2 and pulled a P0068, which is throttle body perf. ECM/PCM

so it runs fine now but im kinda worried

ideas?

oh, and since ive had my injen, when im not on hard throttle but just pressing the gas, i hear hissing, is this bad???? i think its the intake, i might just buy a recharge kits...if not, what lines should i check?
