My 95 manual trans Legacy has a bad vibration that occurs when releasing the clutch. It feels like the drive training is 'bucking'. If clutch is released carefully it is smooth with no vibration, but if a bit more torque is applied I get the bucking. I think it might not actually be the clutch since when released carefully it is totally smooth with no vibration. It's been tough to pin down since it only does it excessively when actually driving, more when starting from a stop, but also when shifting gears if motor speed is not matched to next gear. I've tried blocking the car or holding the brake while letting the clutch out to slip a bit under torque and I don't get much doing that. I'm imagining this might be a motor mount but haven't seen good access points to check that. It seems particularly bad when starting in reverse, especially if backing up a hill a bit. Any ideas on how to troubleshoot this or check the mounts without having to tear it all down? Thanks.
Hell folks, long time lurker first time poster. Having a heck of a bad week with my much loved outback (2004, 2.5l, Canadian). To keep things clear I will stat at the beginning... Just before Christmas, the wagon all of a sudden started to stall in neutral, or when I would press the clutch, this seemed to happen randomly when the car was warmed up. The problem went away for about ten days, only to reappear with a vengeance. (Check engine also appeared) so we bit the bullet and took it to a local garage. They said that there were misfire codes and changed the plugs/wires/coils, later in the day they called back and informed me that the problem was still there and that everything associated with the intake was heavily carbonized. So they did and injector cleaning,and cleaned all of the sensors. After that the problem was still present, they said the egr valve was too carbonized and beyond cleaning. I retrieved the car from them, deciding to find a replacement egr on my own. After removing and cleaning the egr myself (10 min job, was nice and springy after) the car seemed to work perfectly, leading me to believe we had been fleeced... The next day, leaving the city, everything was fine, until the car warmed up. Now my problem is: around 1-2000 rpm the car kicks and bucks like crazy, once past 2000 rpm the car works fine but a little jerky when giving gas, i re-cleaned the egr thinking maybe it needed further cleaning. After testing the car again today, same problem, after the engine is good and warm, it struggles and bucks when driving around in first and second gear till you are past 2000 rpm. After getting a big bill from a garage that didn't fix my problem I am dreading dropping more money at this than I have to. Anyone else have any similar experiences? Or can help me figure out what is going on? Thx in advance
melissak7 posted a topic in 1990 to Present Legacy, Impreza, Outback, Forester, Baja, WRX&WrxSTI, SVXI have a 2000 Subaru Impreza it has 130,000 miles on it. Problems started a few months back and I have tried several things to fix it to no avail. It hesatates when starting off then gets a surge of power once over 2500 rpm in every gear. It has a very bad jerking and bucking. The first thing I tried was to replace the fuel filter, then plugs. I then got codes and it said the accerator positon sensor was bad, along with downstream O2 sensor. I have replaced both of these still not better. I had the codes read again and now it says the idle sensor is bad? My question is would this cause the problems I'm having?
