Hi folks thought i had eveything running on the volv! but now i have back pressure can any one tell me if this can be connected to the lambda sensor as this is showing on the warning lights panel ,
Thanks Patmcg

 

Yes and NO....The lambda light means that there are codes stored in tthe computer so, first you will need to plug in a code reader or read them off the DTC is your car is 94-95. Mostly the codes are related to O2 sensors which might be the effect of high crankcase pressure resulting in higher emmisions BUT.....I would do the PCV job as a priority to make sure that it doesnt take a toll on the rear main seal ( which is PIA and expensive).
Chime in more information to get accurate diagnostics.
