Re: Help identifying pinging/rattling
Still chasing this issue, new plugs, wires , even bought a new distributor thinking it may be
The issue. Check me out on this, I was thinking possibly predetonation, kept backing the timing off, ended up at ridicules ATDC numbers. Then decided to go the other way and it seemed to get better. Any chance I was to far retarded and that would cause a pinging sound in the exhaust? I feel like I have a good knowledge base on timing and tuning but this is driving me crazy.
