New Maf sensor from Vauxhall then

[Linixs]

You reckon?

If unplugging it makes the fault disappear, then it stands to reason that the thing you unplugged is faulty...

[Linixs]

Ok.. fair enough. . Thanks

[Linixs]

Ive had a code reader on it and it gives

P0170 fuel trim bank 1
P0141 O2 sensor heater circuit bank 1 sensor 2
P0036 HO2S heater control circuit bank 1 sensor 2

The P0141 O2 sensor heater circuit bank 1 sensor 2. .
I believe to be the exhaust senser.

When I checked it out it was so loose it was wobbling about. I took it out cleaned it and reinstalled, but its possible its broken with the vibrating it must of dun while being loose.

The P0036 is allso something to do with the exhaust senser I believe. .

The P0170 fuel trim bank 1. . Thats the MAF sensor I believe. .

 All these parts expensive for my model of car, so I'd like to get it right as soon as possible to save wasting money So here's my question? Which sensor would you say is the 1 causing the missfire? Which one needs replacing? Thanks for any help
