ive had two diagnostic readings on it from two different companys both have said it has lambda failure. But the lambda on top of the engine has been changed but the bottom 1 down my exhaust hasnt. Ive had readings ov engine failure n so on. Ive put a new battery on had sparks,filter,oil filter. Id got new leads or what ever they are i thought would work :-( but im not messin with them. So its a new lambda sensor for the bottom ov the engine n ive also been told the Cat mite ov gone so been told to take top lambda sensor out to check it. I dont mind buyin the items for it i just want it fixed as the mrs rallyies around with her n baby in.
