I just wanted to pass along to the 1994-1995 SC owners who are experiencing intermittent tach drop and engine miss. I had replaced the usual suspects Cam Sensor, DIS module but the problem was still there. I did a few searches on the SCCoA and found the 89-93 heat sink grease issue. I went to Radio Shack and got a tube. Applied the grease between the stamped steel mounting bracket and the DIS module. The ignition miss and tach drop are gone. Seems like we can include the 1994-95 cars with the 1989-93 DIS problem. Trying a $2 fix worked!
