How's the air filter? This can make a big difference. To test the FPR, put a pressure gauge on the fuel rail. To test the injectors, you really need to remove them and bench test them individually. However, I have been known to pull the whole rail, point the injectors into a large tray and crank the engine. This gives a good idea about the spray pattern - It'll show up a badly clogged injector - but it isn't recommended practice. What about the AMM? Have you tested it? Have you tried replacing it? Good luck. -- Grunff
