93 surges
I have 93 LT1 in my 81 corvette. I'm having a surge issue. I have had computer rebuilt,new o2s,knock sensor,scanned and tested all sensors,checked for vacume leaks,installed new plugs,checked and replaced bad wires.
but I still have a surge at idle and higher rpms when in park,[2500 rpm]
so cant get to pass emissions. scan shows a knock,but doesnt show that it is trying to fix. right bank runs rich. also shows no codes.
the crazy thing is, when in gear driving it runs fine,good throtle response,tach holds steady without the surging.
can it be in chip or memcal?
any advice would be appreciated.:
