hi,

so i did a compression test on my civic to see if it is worth pouring more money into. i got

180
160
170
180

are these good numbers? do you think this car has much life left in it? i was going to replace a whole bunch of things but i don't want to dump money into a sinking ship/civic. the only number that really concerns me is the 160. i tried that one again just to be sure and yep...got 160 again. what do you think it is? i don't have smoke coming from the exhaust that lingers and the coolant and oil looks good. the car does some times struggle to accelerate and gets only 24 mpg but i just attributed that to my cracked exhaust manifold which is one of the things i was thinking of replacing.

 

awe c'mon someone must know. on a similar note does anyone know if pb blaster is safe to use on an o2 sensor? i ask because my o2 sensor seems to be seized in my catalytic converter.

also if it helps i had a check engine light for a cylinder misfire on cylinder 2 a while back but hasn't happened since. i guess cylinder 2 is the one with 160 psi compression.
