Ok i need assitance. Ive got a 99 Camaro SS with an 04 GTO motor in it. Its got a little bit of headwork, G1 cam and pretty much every bolt on. But today it through some codes about the TPS which i replaced and its running Lean on the 2nd bank. Well the problem is sometimes ill blow the tires off through third and sometimes its got no power. Any ideas or suggestions it could be?
