Diagnostic gave me code P1151 - Lack of H02S21 switch - sensor indicates lean. From what I can gather its the upstream bank 2 sensor, but don't know what side. If anyone could just end my suffering and tell me exactly which O2 sensor it appears to need I will owe you my firstborn... :rolleyes: '98 SVT E0's with Yoko's B&M K&N and a hot blonde ridin' shotgun

I have a 1st, 2nd and 3rd-born, so if you don't mind I'll pass, on the reward. 98 Mystique LS v6 atx 110,000km 97 Contour LX v6 atx 125,000km stock CD on LS, cass on LX spoiler, tinted windows on LS only 4 wheel discs on LX only All other available options on both

Someone must be smiling down on you . -Kurt "I'm a little sceptical of that internet thing. After all, what's it got besides information?" -DB, 1/97
