My subaru has passed 260000 kms, probably a lot when you think about it. Anyways, my subaru does not accelerate when engine is warm enough. When i press gas pedal, it is just stays on same speed. For instance when engine temp. is on middle level, and i am driving on light highway with the speed limit 80 km/hr and when I start accelerate from sixty to 80 sharply, it would not accelerate. It is just stays on 65 and then speed even drops. I think it happens because of cold weather. Another question. When engine temperature just started rising, outside approximately 2 degrees Celsius and I start driving and then stop on the red light, after lets say 2 minutes, car's engine and car itself starts shaking. Why?

Sir,

You can check fuel pressure and Low fuel pressure may cause a lean trim mode so the PCM will compensate by adding more fuel to the fuel injection system to compensate.

Also, remove the vacuum line at the fuel pressure regulator and check for raw fuel indicating a ruptured diaphragm. A flaky fuel pressure regulator may cause longer than normal starting but the fuel pressure check will test it. Check at fuel pump prime, at idle and with the vacuum line at the fuel pressure regulator on and off.

Thanks
Good luck

Problem might be the air control valve, it's located at the right side rear of intake manifold and has a hose going to the air intake duct from the air cleaner, as a test you might try pinching off that hose when the idle is a problem.

it is big end bearing.

No, just keep an eye on it to see it does not start staying on longer and longer. The oil pressure sensor my be a little off,and at worse the oil pump is a little weak. Just keep up on the oil changes.3500 miles max.
