Misfiring 182

[alexr19]

my 182 developed a misfire a while back.
so to solve it, the leads and coil pack has been changed. grey sensor (side of the inlet) also changed.
all the spark plugs are clean and good still and the injectors are working fire.
my mates diagnostic reader says fault p0110 o2 sensor circuit 1 i believe. is that anything to do with the lambda or anything?
any help would be greatly appreciated

Probably worth changing the primary lambda sensor

im going to have a mess with that tonight. its one of the few things we could think off that could cause the issue

It can be a right toad to get undone so be warned, I had mine done by fella doing my MOT as I couldn't shift it for love nor money.

I've managed to get it out! I went he man on it and it gave way. It was more difficult getting the clip up done. Unfortunately I didn't get chance to leave it running as dinner ready so there will be another post on this thread. It could be good, but knowing my luck it won't have done anything

So with the new lambda it idles better.
Took it down the road and it seems like when it's on more than like 1/4 throttle it's misfiring. Surely someone knows. Throttle pos sensor maybe?
