P1128 & P1130 Fault codes advice
I got my durametric working on my 99 boxster. I got a P1128 & P1130 code which tells me oxygen sensing range 2 cylinder (1-3) and oxygen sensing range 2 cylinder (4-6). should I replace oxygens sensors? car has 77k on it. is replacing oxygen sensors difficult to do for a diy? Can anyone give me advice on how to resolve these issues?
