    Lambda Problems

    I had problems with my ABY over boosting and suffering from poor performance so eventually I found the lambda to be faulty (only covered 22K) So I replaced it hoping it was just one of those things? Wrong! 3 weeks later it's up to its old tricks again? Any ideas why? It has been chipped but allegedly put back to normal but I have no way of knowing for sure?

      Thanks! I've cleaned MAF plug, but no difference. I checked all vac lines for leaks with 16psi and none found. I'am gonna check the turbo hoses but i need to build and adaptor to fit the air line first. The problem is the Lambda is fouling up quickly and causing the symptoms cos when i clean the lambda with the air line (reduced pressue) its ok for a bit then! 2413 keeps appearing all the time (which i belive to be running rich???)

        Air leak or dodgy MAF.
