2005 Subaru Forester engine revs to as much as 2500 RPM's intermittently.

Maybe the button on your remote has crud on it?? If it's a sealed remote, it in all likelyhood, needs replacement.

Most likely, yes.

hi yes it is a good idea to replace the oils sooner as it doesnt take much for them to get dirty in subarus, so the sooner you replace the oils the longer the diffs,trans and motors are going to last we usually recomment to customers to do the oils as following, turbo engines around 10,000km, trans and diff oils around 50,000km

Manual or auto trans? If manual, check fluid level. Grinding noise could be u-joint starting to fail, or even wheel bearing.

No ... once you start the synthetic you should stay with it ... continue to use the recommended weight. 75000 is really no miles ... This engine should go for 175 to 200,000 properly cared for.

Your auto parts store that sells Fram can give you the proper filter.

If your talking about replacing your Forester Clock module, you can find helpful tips at www.subaru-clock.com. If your clock is not working, it is most likely the clock module, which can be refurbished inexpensively at the aforementioned site. A "dead" or intermittent clock display is a common problem with certain years of Subaru.

First suggestion is go to AutoZone and get the error codes read (for free) -- this'll probably tell you exactly what the problem is.

Go to autozone or similar and have vehicle scanned for codes. This will give you a idea what's wrong.

There is a chance that the VSS (Vehicle Speed Sensor) in the trans is bad. The ECM (computer) needs to know how fast the vehicle is moving, and what load it's under in order to adjust engine RPM and consequently emission controls, trans shift points, etc. Hope this helps.
