Hey guys so I bought a 2000 camaro it's been sitting since 2008 and the car has absolutely no power at all and it has a slip cold air induction kit Mti clear lid de screened maf headers 3200 stall and a tune. I thought it would just need a tune up so I changed the plugs wires fuel filter fluids and cleaned the maf but still no power. Any ideas on what it can be or is it just a lemon car has 150xxx miles

Idk they guy I bought it from said he didn't ask questions about the tuning he just had it done by speed inc in Illinois. And. I am guessing the sensors are still stiock. Is there a way to test them so how..??
