Question about Subaru Impreza

1 Answer

What causes sudden loss of acceleration with increase in rpms?

I have a 97 Subaru Impreza. The other day, I was driving when my acceleration decreased and my rpms increased. Now, most of the time the car turns over but it's like it's in neutral even when the car is in drive: press down the gas and the engine revs, but the car doesn't go anywhere. I thought it might be a transmission issue? The car has transmission fluid and just had an oil change, as well as a new radiator/water pump/timing belt all put in.

If engine is revving and in drive and does'nt move must be a gearbox /drive train problem,is it a manual gearbox ? if it is then i'd say get the clutch changed as pressure plate failure would cause this type of sypmptom let me know how you get on

    No, it's an automatic (should have mentioned that in the question).

    ok no probs , have the tranny fluid level checked even might be worth changing it as might be the original fluid fro new , unless you have had a change done

    Transmission fluid level is full, and I'm 98% sure that it was refilled when the radiator was replaced.

  • steve May 06, 2014

    sorry you did mention the fluid level in original post , have the OBD codes read as could just be a sensor but i suspect it may be more related to the tranny which would need inspecting by repair shop for a definitive diagnosis sorry cant be of more help

SOURCE: "Humming" or "bearing" type noise in left front at highway speeds

That's a hub bearing. Replace the one that's doing it. I'm assuming this 'roar' is coming from the front, NOT the rear.

Are your cooling fans working? that will definately be a problem if not working. if they are working shut car off and feel the radiator is it the same temp all over or is it hot in only top or one smaller area. if you do not have same temp feeling on all of radiator your radiator may be plugged.

SOURCE: the engine rpm's increase and decrease when in

Does your van have the V-Tec engine? If it does, you will have to take it to a dealer to get it fixed. What is happening is one or more of the solenoids under the valve cover is malfunctioning. The result is the surge in rpm's and the rough transition. You could try an indy mechanic but any mech worth his salt will tell you to take it to the dealer.

JC Whitney has them. There are models that handle CLUTCH systems, by measuring RPMs and any sudden change kicks system off.

There was a sensor that cut the ignition if the turbo was over pressuring. Was a pretty violent jerking, felt like it was tearing the engine mounts out.

Rpms drop on acceleration on 94 subaru impreza L

If your car has coil packs it is most likly them. Some Impreza cars especially the Turbo versions have individual coils built into the lead at the plug end. If your car has these then they crack down the side . If you take them out you can see a fine crack in the plastic. You cannot fix them, they have to be replaced. Check to see if you have them, it might help.
