Thanks again to all! I think I will look at taking off the throttle body for a good cleaning. If I do, is is it required to replace the seals, even if they look OK? The engine has 140K, moreover, I had the fuel system cleaned and I run a quality cleaner throught it every 4 months. I replaced the: Coil, plugs, wires, air filter, and o2 sensor. Would the cam/crank sensor affect performance without the cel coming on?

I was not refering to the MAF Sensor but the rather the two that are attatched to the throttle body. Recently I had the block completely rebuilt.However, it still doesn't run quite as smooth as I would expect,morever, its not bad ( a little course), just not up to my standards. I want it to run like it just rolled off of the showroom floor. I noticed before I replaced the PCV that the air box had a sticky film all over it. It is also probably all over the intake mainifold. Fuel economy is excellent. Thanks for the tip on the spray cleaner, I will buy it.

I am going to replace the aging injectors on my Forester; The PDF manual shows that to do so one must partially take off the power stearing pump. Is this really a must? Or, could I maneuver around it? Its cold here, and I want to do the least amount of work possible. Does anyone know: If the sensors in the intake are bad/ weak/ dirty/ will they send a signal to the computer and will this cause a cel to come on? Can I remove these sensors to clean them with carb cleaner? Thanks in advance for any advice!

I agree! Moreover, I recomend also complaining in writing. Don't let them get away with the old, " thats just how Subarus are." My friend has a '00 outback, with 80k, 2.5, with nary a tick. -
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!

Its most noticeable under acceleration. The engine lacks smoothness, not rough running, but just not quite as smooth as I would expect. I am thinking about replacing the sensors in the intake, and fuel injectors. The Forester is not as well insulated as the Leggacy or Impresa, thus I will be working on this issue as well.
