I might cry

Old's got a point. Frustration is the single worst enemy of progress. There are certain "givens" with working with engines... New doesn't mean good. Expensive doesnt mean good. If a human builds it, "stuff happens". The thing most peopel get frustrated with is when they are at the end of thier understanding. That's when "it doesnt work right", cost, and patience's end all come together. Some things are hard to mess. Up. Some ain't. If the car pings, you have fuel, ignition, or mehcanical reasons. Eliminate fuel and ignition if you can mess with them and it stops or changes. Last is mechanics. If a cam is advanced, or not degreed right and inadvertanly advanced.. Or there's a single sharp in a the right spot, or a gasket that doesn seal right, or a valve seal that lets too much oil in... So, post everythign you know. We don't need names. It's irrelevant at this point anyway. The cheapest way is always using what you got...
