Sputtering and missing?

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.
