new tripoli,

I recently rebuilt my throttle body and installed a new biss. Now im trying to set my idle and when I go into link and groung the timing and diagnostics pins the idle just surges. Ive checked for boost leaks and the only leaks i had were the injector seals. I replaced the seals and still had a problem with them leaking so for a temporary fix i added an extra oring to the lower portion of the injector to put more force on the seal to the head and its not leaking anymore. I cant find and other boost leaks why does it surge when i ground the pins. if i just ground the timing pin it doesn't surge. The base timing it set at 5btdc and the tps it adjusted to .63v.
