Just had a major service at 75k and running perfect since, then all of a sudden it won't start, idle steady or drive properly.
I have to hold the key for 5 seconds to fire up and once ticking over the revs bounce between 1,500 - 2,500 vigorously.
Pressing the throttle has two effects, either cut out completely or slightly rev with little response.
Fault scanned and it came back with p0113 intake air temperature circuit high input and p0141 secondary HO2S sensor 2 heater circuit high input.
I have replaced the IAT sensor and this has improved the rev hunting and ticking over is back to normal, however I'm still getting power loss when on the throttle and I've noticed the car is using a lot of fuel.
I'm unsure if I should replace the second oxygen sensor as the fault code is showing this or was this only coming up because the IAT sensor had thrown it out?
