Re: 156 2.0 TS 1999 Model Idle Problems
I am having an idle problem also, but I think mine is caused by the breather system which also has an effect on the fuel pressure regulator. Over rich mixture on tickover, hence the idle problem. I have to find the time to sort mine out. Mine will tickover all day long, but not smoothly, it sort of fires on all cylinders, then misses a turn, then fires again, but all day long! Have tried cam timing, throttle body, MAF, plugs, coils, reset ECU. As I said, my last hope is the breather system, might be useful for you to try also.
