got a reco'd fpr installed which is missing the 87h - heated oxygen sensor pin that my original fpr does have...

since then 'red' has been idling / driving quite rough, slow (slight delay) in accelerating and is using considerably more fuel than it used to...

here's a couple of pix of both sides of old fpr and having read here how easily they can be 'fixed / resoldered' i thought i'd have a shot at it...

problem, , , i'm a newbie at any type of car work though fairly good with common sense and hands

questions:

a) are my current symptoms caused by reco'd fpr which is missing the 87h pin (and if you're patient and know: why do some fpr's not have all the pins - in particular the heated oxygen sensor?)

b) looking at the pix of the original / faulty fpr, do you see any particular problem at any given point, , , can i clean / resolder / fix or should i leave it to a 'shop'?

i'd love to fix the faulty one and re-install in 'red' in the hope that it will restore it to it's original smooth and swift condition :)

kindest thanks in anticipation :)
