The workaround is removal of the spacer under the Crankshaft Position Sensor. Always a good idea to measure the sensor length & the depth to the crank reluctor wheel to insure the gap is correct (0.020" ~ 0.050").

The "shim" on the few early 1990 models I have seen, was stuck to the block, so you may have to look close to see it, if it is still there.
