E-303 idles mean as hell I thought it was a mild cam.

Hey man, just out of curiosity if your still willing to give it a shot...
At your next fill up, fill it with 93 octane or more (I don't know what you have for pump gas) and fill it with that. After about a quarter tank gas, adjust your timing to 16-19 btc. (And don't forget to disconnect the spout connector ) Reset computer and the IAC because I want you to now, lower your idle. Set it to about 800-900 on a timing light, not your factory tach. Recheck your TPS and give it a full week. See if it helps. Can be more things but its not in front of me. (Kind of hard over the computer).
I do not claim to be an expert, and I claim to know nothing people tend to leave me along too. Know you say that the timing is way to much, don't stress. If it starts to ping with a moderate load then back it off 2 degrees. (But it shouldn't because I was able to run that much in an iron head combo.)
