Question about 2003 Subaru Legacy

1 Answer

I have a 2003 Subaru Baja with 126k. Recently has developed what I thought to be a misfire. When I pulled the spark plugs they were loose and covered with oil. I changed the wires and plugs and still have the misfire. I changed the coil pack, still have a misfire. I rechecked the plugs and the wires, no oil. The car will idle fine but have a strong buck when accellerating.fuel filter was changed 2yrs ago. Any ideas?

I would replace the filter and verify the fuel pressure. should be 30-40psi but I dontt have the exact spec. The oil in the plug tubes may be caused by leaking valve cover gaskets.

Checklite came on and car has been missing lately as if oxygen sensor is faulty or fuel pump is failing.

  1. If you haven't changed your Spark Plug Wires, go ahead and change them. Most of the time this will fix any misfiring you have.
  2. If this doesn't fix your problem, get your codes checked and report your findings.

Check the firing order tu might have installed it differently, clean the Hi-TENSiON wire terminals on the distributor cap and to spark plugs, oxidation makes contacts to these points might have attributed to the problem! The oil must have leaked from the o-ring seals around the TUBE where u put the spark plugs! It also makes the spark plugs misfires! Replacing these o-ring seals, u have to pull down the valve cover, u will see the rubber around the tube, pull it off and replace w/ new one, clean the area first and put a little silicone sealant! Put everything back! Thats it! Taaah!
