I would get the car aligned, and also check the motor mounts on the engine.

BAD GAS MILAGE


Sometime when you do a fuel injection cleaning it will mess up the O2 sensors and that what is use to correct fuel trim long and short term. Use less you have a vacuum leak that will also cause the fuel mixture to richer up, were is the idle at

Poor gas milage?


Thinking you are getting poor gas milage,Your engine is running smooth,no misses,Engine runs smooth while accelerating up a hill, Still poor gas milage, Check your tire pressure. I have a 1999 Chevy Blazer 4x4, 4.3 Ltr. Auto, loaded. I have just over 154000 miles on it,I change my fluids every 5000 miles. Summer driving milage got real bad. I drive a Blazer hard. I tow a 16ft trailor usally loaded to the top with wood. Tires get hot in the summer, while in the winter, they stay mostly cool. Always check your air pressure.Most vehicals are equipted with radials now days, So if you think a tire looks low, check it, Usally they low. Usally in the winter months, nobody checks tire pressure. It really does make a difference. I went from 17.2 MPG to 19.5 MPG, while pulling the same trailor loaded with wood. I cut my own wood then stack it in my trailor to sell. I have Good Year Wranglers size: P235/75R/15 I just replace these with new ones. The old ones are going on my trailor. Counted milage on tires are 65000 Miles. Tires were rated at 40000 miles, Under normal use.

1999 Subaru Forester has developed a shake when accelerating, esp. between 20-30 mph. Wheel bearings replaced - didn't help. Tires checked, balanced, etc. - didn't help. Front end allignment - didn't help....


Auto or 5-speed?
Subarus have CV axles in front and back. And a drive shaft from the center differential of the transmission to the back differential.

Yes, it could be the drive shaft or axle. If you turn the car hard left or right do you hear any noises - usually a 'clicking' sound? This is likely a CV axle in front.

Check the fluid in the transmission (Automatic) (info is in the Owner's Manual) to make sure it's full and/or gear oil in the front differential.

If it's an Automatic transmission, the fluid may need changed - NOT FLUSHED - if it has more than 30K miles since last changed.

Bad gas milage


I know they didn't get the greatest fuel mileage, but I've worked on motorhomes that got better. Something doesn't sound right. You've checked all the obvious like, sticky calipers/brakes, proper size & pressure on wheels/tires, transmission shifting as it should, proper front end alignment,etc.? Oxygen sensor changed lately?

Noise and vibration above 50 mph


Sounds like front differential or front drive axle issues. Check the front differential gear oil then take er' to the dealership before you end up spending a bunch of $. Most people change their oil frequently in the engine but forget about flushing the transmission fluid and changing oil in the front and rear differentials. I have three Ford 4X4s. Two which really get used hard. The 93 has 311K miles and still runs excellent. Trans and differentials get a fluid change every 25K miles and moble one synthetic engine oil changes every 5k miles.

I have another question


Did you support the vehicle on a lift and run it, with wheels engaged?
Since you have changed all the usual suspects, Have you checked the hub bearings? It could be that, or, something stupid like a backing plate hitting a rotor.
Regarding the cat/o2 sensor thing. Cats do go bad, so do o2 sensors but, generally a code for an o2 sensor indicates a problem elsewhere, causing a lean or rich condition in the exhaust pipe, beyond the parameters of the o2 sensor. PS: check warranty on cat. generally it runs longer than many other components.

sounds like c/v axles (front drive shafts) they will make a clicking sound normally when turning sharp and accell at the same time at slow speeds / look at the axle boots and look for grease on the inside of the front wheels leaking out the axle boots
