jon38iowa Posted November 9, 2006 Share Posted November 9, 2006 Last week I got my Forester back after having the block rebuilt(133K).It runs great, plenty of power, etc,.However, I still notice as before, a little shake in the front end as I'm sitting at a stop. No dash lights come on, and the tach is steady. Last time I looked at the intake (Plastic box in back of it) it was sticky with a gum like residue. Recently I replaced : Fuel filter (ran a cleaner through the tank), wires, coil, and the much talked about front O2 sensor. My question is this, which one of these listed would likely help the most: Replace- the fuel injectors the sensors to the intake manifold Spray the intake (internal) with Seafoam. Thanks in advance for any pointers! Link to comment Share on other sites More sharing options...
bkcraun Posted November 9, 2006 Share Posted November 9, 2006 Does it stop if you put it in neutral? If so, many subies have this "shake". I'm not sure if anyone has figured out why. Link to comment Share on other sites More sharing options...
Manarius Posted November 9, 2006 Share Posted November 9, 2006 PCV valve might be shot. That could account for the "gumming" in the intake. Link to comment Share on other sites More sharing options...

Sorry Manarius: I forgot to write it in, yes it was replaced as well.... If I put the car in nuatral it does stop the shake. Link to comment Share on other sites More sharing options...

Well, I'm not sure about the intake then. The shaking is from the AWD system. Every Subaru with AWD that I've riden in has this sort of "shaking" issue when stopped and in drive. If you really don't like it, just drop the car in neutral at stops - I do. Link to comment Share on other sites More sharing options...
porcupine73 Posted November 10, 2006 Share Posted November 10, 2006 Some people have reported having this sort of shake when stopped in gear after replacing the axle half shafts. Link to comment Share on other sites More sharing options...

Thanks, but I have not had the axles replaced, though I have had the boot cover (inner passenger side) replaced. Link to comment Share on other sites More sharing options...

Manarius Posted November 10, 2006 Share Posted November 10, 2006 I've had vacuum leaks cause this... Vacuum leaks usually cause weird idle...like it jumping up and down randomly. If he's just describing that the car when held to a stop while in drive vibrates a lot, I'm rather sure it's just the AWD system trying to move the car.
