Tony knows his stuff in real life and is generous in his help. He isn't just sat behind his keyboard. He has years of practical experience, wrote the rcr engine and electrics courses and accompanying notes, and is also humble enough to acknowledge where other people know more about certain engines or topics than he does. The only mistake he seems to have made is mentioning your original engine diagnosis didn't make sense to him and to check it out, otherwise it could be an expensive and unnecessary red herring, which for some reason wasn't what you wanted to hear. Not sure why that would be, unless you want to waste time and money needlessly.
