I could use some help with my 1998 Sport. The MIL came on and diagnostic code P0135 pops up, oxygen sensor bank 1. OK, so I buy one and install it, but the MIL is still on. Seems that it needs a drive cycle to clear it, but besides that outrageous procedure, you have to start with the MIL off, but mine is on. How do I turn it off? And, is the overly complicated drive cycle procedure actually necessary? I've seen several different ones, and they all seem pretty ridiculous.
