Hi people, ive just bought a 94 wrx wagon gc8 this is my first subaru so havent got a clue really, ive got a couple problems first being speedo cable. The speedo was bouncy when I drove it back from Birmingham to Plymouth and check engine light came on a few times, it felt like it was holding back when light was on, I took the clocks out yesterday to see if cable had come away from the clocks but couldn't really tell, then when I put it all back I have no speedo at all! Is a new cable a easy job or garage job? Other thing the boost gauge is set to 1.75 bar is this ok ? And how do I turn it down ? Any help will be much appreciated guys thank you
