hmmm, ok I tried to move it by hand and there was a lil bit of binding. So i readjusted the screw and then tried to move it by hand again. No binding the second time around. Cleared the CEL with the SCT tuner got codes P0135 and P1518, started her up and the noise is still there
so took it out for a test run, nothing out of the ordinary. Came back to my driveway and turned her off then back on and noise cycles again and CEL came back on, so does this mean that I need to replace the whole DSI unit???
