Need Major Help!

[lizb]

My 01 Mustang keeps stalling every time I either rev the engine or just to press on the gas to drive. What could be causing it? I need help ASAP because tomorrow I go back to work. Also can a weak fuel pump cause a misfire in cylinder 1 and 2?

Do yourself a favor and have the battery, battery cables, and alternator tested/checked before replacing ANY parts.

It would be handy to know what the fuel pressure is.

Here's some information on an affordable Windows based ODB2 scanner.
