93 Formula.....Code 43 (knock sensor)
Also, In the haynes manual it says V8's have two Knock sensors under the intake manifold. But here it shows the knock sensor on the RH side of the engine. I'm 90% sure I heard somewhere that on 93's it's on the RH side and there is only 1.
I just looked at the books, damn the Haynes would be confusing if you never did one. Neither the Haynes nor Chiltons had a pic of the LT1, just the 3800 motor and the LS1.
Torque for the sensor is 14 ft-lbs. I don't know if its true or not but years ago at the dealership they said torquing that sensor to specs is vital to it operating correctly.


Either the sensor, the connection, or the wiring.
