I've been tweaking with my ty for about a month now. It all started when it was due for its 1st smog because I had a crooked tech pass it before the rebuild. I added a fuel pressure regulator, put a hot thermostat and replaced with a 160 (after smog), and refilled the fluids. I actually got the truck to pass CA smog by regulating down to 32lbs and adding a solution call sure pass smog. Ever since then I raised the fuel pressure back to 45lbs and it hasn't been running to well. I decided to tune it up oil change and spark plugs. The plugs were all fouled up: 5 of the 6 were kinda corroded with whitish carbon and one was just brownish red. I put in the NGK TR6 because it looked like the TR55 were running hot. Everything is mechanically sound but I there's a little knocking going on. I hooked it up to the data master and the knock count is pretty high (levels range on rpm), don't know what's causing it. pulls about 10 degrees of timing and idles about 30 degrees advance at idle. all reading in park timing set to zero with brown wire disconnected. can anyone look at my datamaster filr? Any suggestions?
