Hi all I am new to the site, came over from vvoc to try and get to the bottom of the problem with my vectra sri150, basically after having the timing chain done and service I gave it a bit of welly and then all hell broke loose, it was kangarooing, hesitating misfiring, I had to drive down the motorway at 25-30mph as the engine will not go above 120rpm. Chris off vvoc came around my house today with his laptop which brought up the following information:
P0135 O2 sensor heater circuit malfunction
More info:
We checked the O2 sensor readings and got the following readings at idle:
O2 sensor Bank 1 sensor 1 273 mv
O2 sensor Bank 1 sensor 2 880 mv
Air fuel ratio Bank1 sensor 2 (Rich)
Firstly what the heck does this all mean and secondly would this O2 sensor cause the engine to go into limp mode, cannot rev over 1200rpm, idling lumpy, misfiring running like a real bag of cr@p, totally undriveable.
Or is this a fault but something else causing the problems above???
dunno..
