just run down every possible problem. fuel pump/ relays, clogged line (doubtful), you already changed filter, .. next is the fuel pressure regulator (small diaphram valve), and then the fuel injectors. sides that the air side of the mixture.. air filter could be clogged, MAF might not be opening when you give it gas (but if it opens too much then the engine would over-REV), maybe a vaccuum line.. causing a component attached to work improperly.
