i posted about i thought it was the cat that was causing the loss of power and noises well first of all the motor was shaking causing the cat and the whole exhaust to shake causing the noises. But we narrow it down and we its the fuel injectors because when i had water in the gas these mechanics gave me stp, gumount, octane booster, special anitifrezze to dry up water in the tank i poured it all in there everylast one of them so we think it messed up the injectors could this be is this why its running rough and loss of power?
