Question about 1995 Subaru Impreza
I have a 95 subaru impreza lx 2.2 awd and my problem is my car is really sluggish in first gear but after it warms up the rpm goes up and down about 200 rmp at a time and it feels like its losing a lot of power the only thing i done to it is i put a new aem fuel pump a new fuel filter a new fuel surge tank new ngk plugs and wires a new cam and crank and tps sensor. the only thing left i think that could do it is the fuel injectors my car has 165.000 miles on it and the injectors are original. if any one has solutions ill try them out. thanks

SOURCE: Cold Start Idle Issue
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.

I personally would check the fuel pressure. Then I would go back to the coil. I have seen brand new bad coils out of the box. The symptoms of a loss of power point to this component, especially if the car idles well, but loses power when accelerating. Please do not rate this reply - we all are left to grasp at straws since you have changed pretty much everything. Good Luck. Please post the final fix of the problem.

This could be a number of things but i think that your problem sounds like a vacuum leak or an EGR problem. Try listening for leaks and try un-plugging the EGR solenoid valve one time.

SOURCE: intermittant stalls & rough idle
You might have leaking injector(s) or injector O-ring(s). It could be leaking inside the fuel rail feeding fuel constantly. The pressure could be OK because the computer compensates by working the fuel pump harder in order to keep pressure within specs. I have a similar problem in my 99 Outback, it rough idles at stops intermittently. I recreated the problem, I checked it in my back yard, turned it on, let it warm up. Then I put it in gear went forward stopping and going with the e-brake until it rough idled. I got out put some bricks in front of the tires and started checking around. I noticed when it rough idles the transmission makes a constant sound. I would describe it as a fast ticking, sounds electronic. I tried messing with the idle by adjusting the TPS. I noticed that when I set the TPS to where there was little or no signal coming from it the sound would stop and the idle would be normal. I haven't had time to check it again but I don't know what to think of it.
