My Z is having symptoms. My engine is fairly good it only has around 84000 miles on it but today something weird started happening. First gear was good and so was second at 3rd gear my car wouldn't go over 2500 rpm i would literally have my foot down on the gas and it moves like i just downshifted or something and if i keep it on the gas for to long the muffler sputters like as if a cartoon car just broke down. So i drove home at low speed from the base i work at to look in my engine. I found pieces of a belt but I'm not sure where it came from. Also my gas just start dropping like a rock in water idk if that's connected to do my problem. Can somebody point me in the right direction cause nobody in panama city knows how to work on my car and i would rather get what i need to fix my car and do it myself. My engine right now is the original L28E. Thanks for your help.
