Have a2001 Saturn sw2 lacks power when accelerating and crushing but when you pass half throttle it will go better. I've checked fuel press.it is 50_55psi and at low speed and idle runs great

Are you writing that the engine fail to accelerate under a load? If you are in park and rev the engine, acceleration is normal until you try to drive away? There is no one answer for this issue. Possible causes include: tune up needed, clogged air filter, fuel filter or exhaust, timing, vacuum leak, CKP, CPS, ECT, 02s, TPS, EGR, poor compression, bad ground, faulty ECM. Is there an engine light? Even if there isn't I recommend scanning for codes. Please let me know if there is anything else. Good Luck.

My dacia sandero when i change gear the revs dont die down as if the accelarator is sticking but it isnt?

Worn clutch: If the clutch is worn, it may not be disengaging properly when you change gears, causing the engine to continue to rev as if you were still accelerating. This can also cause difficulty shifting gears or a slipping feeling when accelerating.
Dirty or faulty throttle body: The throttle body controls the amount of air entering the engine and adjusts the idle speed. If it's dirty or faulty, it may not be closing properly after you release the accelerator pedal, causing the engine to continue to rev.
Vacuum leak: A vacuum leak can cause the engine to rev excessively or idle roughly. The leak can be caused by a cracked or disconnected vacuum hose, or a malfunctioning intake manifold gasket.
Faulty idle air control valve: The idle air control valve regulates the engine's idle speed. If it's faulty, it may not be closing properly after you release the accelerator pedal, causing the engine to continue to rev.

I own a cadillac cts 2005 my car will not accelerate when gas pushed Starts great & goes into gear

What do you mean it doesn't accelerate? Will it accelerate at all, like gradually build up speed when driving? Or do you mean it doesn't drive at all? Does it rev while in neutral/park or out of gear?

sounds like a sticky Idle Speed control (ISC) valve or muck in the throttle body, try cleaning them first, if that does not work a new ISC Valve will be the way to go.........

i think the problem is the idle\air control module if you have one take it out and clean it. the idle module works when your vehicle is idleing. A clogged throttle body or intake would cause the module to compensate for the problem by allowing air in and around the throttle body bypassing it. so i think some thing in the intake system is clogged.

SOURCE: When I try to accelerate my car has no power!

There could be a couple of reasons. Yes a tune up would be nice. But my not fix the problem. If you are not losing acceleration on straight away but on hill, then it could be the torqe converter. Also have your MASS airflow sensor checked and air filter.

Also check your fuel pressure at the fuel rail. Get a fuel gauge and look for a port on the fuel rail for a port that looks like the valve on the tire. Screw it in and crank the car. You will have to call the part store to find out what pressure it is supposed to be. If there is low or eratic pressure the its the filter or pump
