2005 Subaru wrx check engine light is on and seems to misfire during acceleration. Intermittently the check engine light will flash and car will idle rough (shakes the car), have almost no power, and sounds differently.

Take it to autozone and have them to pull a code on it.It sounds like O-2 sincer

It sounds like you may have a problem feeding the fuel to your engine, I had the same problem with my 89 RS. All the 1989 model's fuel systems were recalled. I think you may need a new fuel pump. The fuel pump is located inside the gas tank in the rear of the car right under the rear axle. The fuel pump itself isn't too expensive, but with other small parts such as the electrical harness upgrade and fuel filter and the labor you should be looking somewhere in the $500 range. I hope this helps.

check engine light on usually mean emissions. ie catalytic converter, o2 sensor.

Drop in to an Autozone, or Pep Boys, or similar big parts store & they will usually scan for codes free. This will hopefully eliminate all the guess work, or at least point everyone in right direction for better diagnosis. If not obvious from codes what the problem is, get back to us and we'll help you out.

Testimonial: "Thanks for the great suggestion . I'll have Autozone read the codes on Monday. Thanks again!"
