melissak7 Posted August 16, 2014 Share Posted August 16, 2014 I have a 2000 Subaru Impreza it has 130,000 miles on it. Problems started a few months back and I have tried several things to fix it to no avail. It hesatates when starting off then gets a surge of power once over 2500 rpm in every gear. It has a very bad jerking and bucking. The first thing I tried was to replace the fuel filter, then plugs. I then got codes and it said the accerator positon sensor was bad, along with downstream O2 sensor. I have replaced both of these still not better. I had the codes read again and now it says the idle sensor is bad? My question is would this cause the problems I'm having? Quote Link to comment Share on other sites More sharing options...
