Grand V8 uneven tickover

(1/2) > >>

Popoff:
My 02 Grand Cherokee Overland V8 (high output) has started to have an eratic tickover, not all the time but when it's happening it "hunts" between 600-1500 rpm any ideas please?  :-k

ronttuk:
vacume leak???

Bishops Finger:
O2 sensor?

Popoff:
Thanks will have another look for any leak, but couldn't see any thing obvious, where is the 02 sensor? (it's scary when I look under the bonnet)! and too really wind me up the passanger side heater will only blow cold  :evil: so the dreaded blend door has gone, had the drivers side sorted when I bought it in Feb  :evil: but on the positive we have just spent a few days off roading in it (Strata Florida was fun) on std road tyres and never got stuck very impressed, but need the lift kit and some cooper sst's  :D  and if you boot it she just go's so well  :lol:

Bishops Finger:
O2 is somewhere on the exhaust system...
