Camaro2LT/RS, I would bet he "tripped" something loke an over rev limit or something like that.....take it in and have the dealer check it out.....BUT what you need to do is just tell them what its doing. or not doing in your case, but don't tell them all the details of how your bro "MIGHT" have done.....once they plug in your car, they'll figure it out. depending on your dealers service manager, and if you tell him you "think" your car "might" have been over reved or something, IF they want to be "dicks" they could use that excuse to deny your warranty....or crap like that. SO, just take it in and tell them: "I don't know whats going on, it won't accelerate must past 2000 rpm" and let it go at that and see what they do.
OH ADN BTW.....CONGRATS on the ride and Welcome to our happy little corner of the net, and to Camaro5. There is a BIG fridge on the back porch with anything you can think of in it...help yourself...of course only take what you can LEGALLY have. Make yourself at home on one of the big fluffy couches, kick your shoes off, put your feet up on one of the tables, yes we are allowed to do that, mom's, dad's, wive's, husband's, girlfriend's and boyfriend's here don't care....and take it easy.
oh...btw....every once in a while a food fight breaks out...so you may not want to wear nice clothes here.
Welcome!!
