**** today i was trying to put the new injectors in w/305cc and everything
went well i turned down my safc like -15% and cranked the car let it warm
up. noticed the rpm was high like 1100 and i usually idle at like 900 so i
thought i was running rich so i turned the knob down but rpm went higher..
so put it at like 5% then then idle went to 900rpm i walked to the back of
the car and noticed liquid(fuel) coming out the tail pipe to i killed the car. tryed
again but this time at -30% it stayed at 900rpm?? so i take it for a test drive
and hear a clicking noise .it can't be heard when idling but at like 1500rpm
in gear you can hear it. i thought it was the injectors so i took them out and
put my old ones in and the same thing...

Any body know whats going on or something i should check?
