I need some suggestions on a reputable Subaru mechanic to troubleshoot my CLE problem. I have done some stuff, but it still comes back on and then goes off for a week and then back on.

I am located in Northern Utah. Salt Lake City north would work best for me.

Thanks for any suggestions.

With some vehicle details we can help even more than that, for free! year, vehicle, mileage?

what is the actual code you're getting?

Advanced Auto Parts, Autozone, and other place will check your codes for free. Let us know what the code is (not what the person tells you they think it is) and we can probably tell you what you need to do to fix it.

 

most common codes are cylinder misfire and knock sensor with EGR and O2 sensors being high on the list too. they are all very easy fixes (usually!).

It is a 99 OBW with about 124000 miles on it. The code is the #4 cylinder misfire (p0304, i think). I have changed the plugs and wires. Still get the same code. I replaced the fuel filter, no change. The thing that I notice is that the idle speed is 250 rpm and rough at lights. After the CEL is cleared I can be driving and it will turn on again at start up or at speed, no change in performance or acceleration.

Any suggestions will help.

Next step is a compression test. If that checks out, you should test the injectors.

also make sure the electrical connectors for the injectors are plugged into the correct injector.....i chased a misfire for months and it turned out that the injector connectors for cylinders 2 and 4 were swapped.......just my experience....something simple to check.....
