I am still having trouble getting my GN to run right after I changed the timing chain. i know the timing chain is instaled correctly but it runs real rough. if the cam sensor is installed 180 off will the car still run? I put new plugs in it hoping that was it but no luck. I put the cam sensor in at TDC just after the 3 oclock position. i then turned the balancer 25 degrees ATDC and used the caspers cam tool to set it. what could be the problem????? please help
