car falls flat on it's face at 3k rpm's

I recently did a timing belt on a 92 talon n/t. Now when it hits 3 grand it falls flat on it's face. The timing points all seem to line up but when the sensor is fully retarded the lowest I can get is 10degrees btdc. It used to be 18btdc

what are you saying that your timming is set to 18 deg BTDC or are you using a logger and it is reading 18 deg BTDC ?

when I shot it with the timing light it was at 18 degrees btdc, so I retarded the timing and with the sensor as far as it will go it's at 10 degrees btdc
