I have a 2002 Forester 5 speed AWD. When accelerating from a dead stop, letting out the clutch pedal, it frequently shakes the car like it is possessed by demons. I combat this by revving the motor a bit and/or double clutching. It does not do it once the car is moving. Also, it does not occur when the car is cold and gets noticeably worse after it has been driven awhile, fairly consistent then but still somewhat intermittent. Once the car is moving there is no sign of it, even accelerating heavily in upper gears. No bearing noise. Clutch was recently professionally replaced. Crawled under the car to check u-joints and drive line coupler. Only thing I could find was the rubber mount in the center driveshaft bearing coupler had a little play when I tried to twist it (very little but enough to see). The shaking feels like it starts in the tranny area but quickly transfers to the back/differential area. Any ideas what is causing this and how to fix it? Thanks, Joe -
The title is a little misleading, but I don't know a good way to describe it. I'll start with some background. 148k miles, just had a timing kit done on the car. Replaced the engine coolant temperature sensor after reading that this possibly was the cause for my rough idle and the engine cranking, but not catching when warm starting. By the way, this has totally solved my problem (fingers crossed).. this forum is awesome and thank you to all those that contribute... saved me a bunch of money on that fix.. But now, I'm just noticing (I don't know if it is because before I replaced the ECTS my engine was always running rough, or because I knocked something loose in the process, or what) when I'm accelerating, it doesn't accelerate smoothly. It seems to get through the first gear normally, then when accelerating through the next gear I can feel (and see the tachometer) the car kind of oscillate between accelerating at a predictable rate then slowing down (but still accelerating) then back up, and down again, etc. When watching the tachometer it will rise, then stop, then rise, then stop, etc. I don't know if this is making any sense, but I don't know how else to describe it. Any thoughts on what this could be, what to check, fix, replace, etc.? Also, when flushing my coolant and replacing the hoses, I noticed a small leak right next to (below) the air vent plug on the radiator. It is right where the upper hose connects to the radiator where that horizontal plane meets the vertical plane. Again I'm sorry if I'm not describing things in conventional ways... I'm not really mechanical at all, I'm just trying to be these days to save money. Anyway, do I need to replace the whole radiator because of this, or is it safe to use come kind of leak stop... if so, what recommendations for leak stop. I needed, I could provide pictures when I get home. Thanks for any and all help. I did do some searching for these things, but didn't find what I needed. I'm sorry if this stuff has been discussed already, just let me know and I can do more searching.
