I have a 1996 Subaru Legacy GT wagon 2.0 twin turbo Import. My problem is after driving for a few miles/about 10 mins, I get a rattling noise from rear, sounds like something loose in fuel tank. Then fault code 22 (knock sensor) light comes on as car looses power/misfires/hesitates but never cuts out and idles/starts perfect every time. Sometimes light goes out and suddenly back to full power for a few mins until it happens again. Also when cold for first mile car is slightly hesitant but no noise or fault light.
Are all these problems related to one thing? Would faulty fuel pump cause rattle and loss of fuel pressure/lack of power. If so, would ECU read this as a knock sensor fault? Or is rattle totally not linked to problem and I need a new knock sensor?
have the same problem?
