i have a 2006 ss/sc 78,xxx GM stage II, CAI, Fidanza flywheel, Exedy clutch, and no cat. Sometimes when i hit 3500 - 4000 rpm my car will start to jerk, wont go faster and wont go past that rpm until i put it in neutral and mash down the gas, then its fine...it only happens maybe 2 times a month and it only happens the first time i start my car... and i have noticed a major drop in gas mileage... went from an avg 30mpg down to 26-27mpg driving like i always do...i have never had any probs with my car before.... any ideas??? Thanks for the help!!!

You need to clean your MAF sensor, along with your TB and then run seafoam through your motor.
