Hi!
First of all, I have a 1.4 petrol.
My A2 is acting kind of funny from time to time. Scenario:
If I'm driving steadily in lets say 60 mph on the highway, it sometimes feels like the car jumps between 75 bhp and 50 bhp every second: in other words,
It's like the pulling power increases and lowers every second. It is only noticeable when I'm driving steadily at high speeds.
My engine management as been on ever since I bought the car, and the only fault code is:
17559 - Long Term Fuel Trim Additive Air Bank 1: Range 1: System too Lean
P1151 - 35-00
Question is: could it be linked to my experience? I have given it a thought.
- Could it be bad connection to one of the four injectors (e.g. ignition comes and goes?). (The spark plugs are fine.)
- possibly a tired valve?
Some say it could be the oxygen sensor (lambda sensor), but in my mind it does not ad up, cause the shifting (between high power and low power) happens so fast, and I believe the lambda sensor operates at much longer time intervals.
Trying to save money and dont want to take the whole engine apart
Cheers
