Hello all.
I have a 01 is300 and yesterday my trac off light started flashing at me and i read on a thread that it can be caused my a misfire. However my temp gauge starting acting up at the same time. After I get over 40 MPH it starts acting up bouncing around and sometimes it just goes straight to the bottom and doesn't move. I just replaced my whole cooling system including all relays fuses and sensors. Could this all be linked to the misfire ?
Thanks in advance
