Greetings,
Recently I ran into some trouble with my 2003 MP5.
Car seems to run normal at lower RPMs (500-4000), although it may not be running perfectly. I simply can't tell. The real problem hits when I start to rise in RPM. Since this car is only a 4 speed automatic, it makes my car really slow. Once I hit 4500 or 5000 RPM it loses all of its power and will stop accelerating, but still climb RPMs slowly. The car also sounds kind of stressed and under more of a load. Basically, as a 4 speed auto that means I have no potential for passing people since it requires a downshift into that RPM range in order to get any acceleration. Hills are impossible as I can't stay high in RPM to go up it, therefore losing speed gradually and pissing people off.
I checked the oil, the level is fine. Transmission fluid is fine. I use 89 octane fuel.
The car also sometimes makes a high pitched and fast rattling/ticking at these higher RPMs, and especially when going up hills. Not sure whether these problems stem from the same part.
I have been looking up this problem, obviously, and have concluded it may be a bad fuel filter? Since it has enough flow to operate at low RPM, but may not get enough fuel at the higher RPMs?
Any thoughts? thanks
