Well checked to see if i was throwing any code because i've been experiancing an apparant loss of power recently (just doesn't pull as hard as it should). Got error code 21, ignition signal circuit. So i replaced the coil with another one and that seemed to help *a little* but still missing power and the code is still there. A few months ago my power steering blew up and coated the area in fluid, perhaps that led something to fail? So wondering what else to check and what other people had to do to solve the problem?
