last week i posted the problem, runs rough at startup. well it was #1 &2 injector connectors loose, and got tight with heat. there is a TSB out on it. the DTC did not show it. but the primary computer did, forgot name but it started with I.. the had to get to injectors to install 2 clips to hold the connector on. So if anyone ever hears this again they will know what to look for. mechanic said normally they just run rough till the check each connetor and find the ones that have come off.
