Bought the iCarsoft PRO, but still find it very challenging to use. At 72 I am not "over tech gifted" and am finding the User Manual I had to print from the internet is not really that helpful to me.
Can read deeper into P0420 that my Foseal Diagnostic did, but cannot understand such things as live "% efficiency readings" from upstream and downstream Lambdas. Yes it gives the readings and that is OK if you understand what they are meaning.
I still get intermittent P0420 codes, despite having replaced each and every part of the Bank 1 induction system and exhaust system, and cannot understand why/how these intermittent codes keep occurring. Manifold Gaskets (6), plugs, coils, up and down stream Lambdas, Catalytic Converter (which was killed by misfiring), checked all joints for leaks. All replacement parts as OE.
Any ideas from anyone would be much appreciated.
Best Wishes and Regards, John.
