I have an 2003 Monte Carlo ss 3. 8 . I have had loss of power . It wont go past 4 grand on the tac. I have replaced the plugs and plug wires, coils, fuel filter, idle sensor, tps sensor, egr, I have had the fuel pump pressure check it is 55 psi. I think it may be the catalytic converter. I noticed they were recalled on the 01 & 02 models why not the 03 models?.
