I have replaced the catalytic converter, the spark plugs, the ignition coils, and it was running fine for a week. Now it can barely idle it sputters no matter how hard you push the gas pedal. It has no power, and I am confused as to what could be causing this. Your assistance would be greatly appreciated.

Hi,

This can be a few different things. First, have you checked to make sure the fuel pressure to the engine isn't too high or low? If you haven't, start there.

Here is a link that explains how it's done:

I attached the manufacturer's fuel pressure specifications below. See pic 1

If that checks good, then I need to know if the check engine light is staying on while the engine is running, if you have had the computer scanned for diagnostic trouble codes, and what the codes are which are present.

Let me know.
