:wtflol: What's going on guys! For some reason I can't get code 21 to clear. I have done everything I knew. Well.... I think everything to clear the code. What happen is my O2 sensor wire fell on my turbo and the wires had melted together, so I cut out the bad ones and wired it back up. Now, the code21 stays on and I have unhooked the battery and pulled the EFI fuse. Could it be that my ar/fuel ratio is not correct? Just did 550 ssafm defcon dp fpr 225 fuel pump.
