Engine misses?Grand Cherokee WJ
Hi Folks, Thought I.d ask questions in the land that made my baby. I,m in UK. Here goes .I have a 2000 WJ jeep . It is auto and has been converted to LPG( good thing in uk as a 18mpg motor is not runnable but LPG means its half price for fuel or double miles!! Any way when on gasoline it hunts on tickover and if not caught quickly can stall. This when its getting warm.Wen switched to LPG(Liquified Petroleunm Gas) its fine. I have a code that says OXYsensor in emmissions failed? Would this do the fault? Or is it a matter of cleaning various intake area/sensors etc. Hope for some help.

Think I.ve cracked solution. I had removed battery. The missing /surging was because the ecm had to relearn idle speed.Also have replaced after cat sensor. Doh.
