I have a 2001 ford Taurus SEL 3.0L Duratek engine, car idles fine, but will not go over 2000 rpms whether in park or in gear. the fuel pump and filter were recently replaced.

Check your fuel injection system.

many things can cause this. the most common problem would be that the timing is slightly off. (fixed sometimes by adjusting the distributor) it could also be a bad fuel pump (or clogged fuel filter) this would allow enough fuel to run the engine in park but not enough to run the engine under stress. clogged air filter could also cause this (not allowing enough air into the cylinders). I would change the air filter and fuel filter. then crank the vehicle and slowly turn the distributor (finding the best idle position) then see what happens. lastly replace the fuel pump.

Check engine timing of cam and crankshaft, inspect your timing belt. check to see if your fuel system is faulty. Check for a clogged fuel filter, or if your fuel pump don't run at all, replace the "fuel pump relay". Sometimes your fuel pump will run, but be too weak to hold pressure, which will let your car idle somewhat, but be too weak to run the engine at speed or under load.

Could be IAC sensor maybe TPS sensor[RPM].

check your fuel filter first whether is blogged due to dirt. check if you have a fuel pressure tester about the fuel pump pressure.finally check whether the fuel pressure regulator is working.

the first part of problem could be sensors or bad ECM (computer) second part of question sounds like you are low on antifreeze.

It is most likely you wheel alignment (costs about 20 bucks to have your wheels aligned) or try checking the tire Pressure to make sure they're all even maybe hope this helps

most likely tune up time. spark plugs usually act up around 60k

you have a torque clutch problem chan your torque transmission

Disconnect the battery completely, try turning the key with the battery disconnected. Put the battery back together. The check engine light should be off now..
