Alternator?
Voltage Regulator?

If the noise sounds like a weeeeeee that increases in pitch as the RPMs increase, and you haven't heard this sound before the 'problem', suspect the alternator...

SOURCE: 02 impreza wrx problem with turbo PLEASE HELP

This is not the turbo it is the over-powering the clutch, it happens in 5th because that is when most worn clutches slip, it is the biggest load, replace your clutch.

SOURCE: car lurches and bucks, rpms erratic on acceleration on hills

You could have any of these problems:
1) vacuum leak- broken air hose or disconnected air hose.
2) water in the gasoline- add a water remover to you gas tank.
3) bad or disconnected spark plug wire(s).
If this were my Forester, I'd take it to a mechanic who has a electronic engine tester..

SOURCE: 1998 Subaru Outback Wagon Grinding Noise/Squeaky Brake/Gas Gauge

The first issue, I would have the brake calipers checked for either a pin stuck or one of the pistons stuck, It is a dual piston caliper and sometimes one will stick causing pad to angle slightly. While inspecting the brake issue also check your wheel bearings, which may be the squeak. On the fuel issue, I will tell you a secret, LOL, but Subaru has set the fuel gauge to read E but still have about 5 gallons of fuel left. I use US measurements, but trying to use my head I believe you are getting about 22-24 MPG from what you said and that is pretty good. I hope this helps a bit and have a great day.

1998 lexus gs300 runs at 2800 rpm at 65 mph


At a steady 65 mph, the torque converter clutch (TCC) is engaged. When you accelerate, the ECU disengages the TCC to gain extra torque for acceleration and then re-engages TCC when speed is steady. Its kind of like having an extra gear.

My car is jerking while accelerating and reaching certain RPM


I would look for a fault in the ignition system such as a cracked spark plug. Might need a scope check to put your finger on the problem
