[V8] RPM Sensor

[William Gutierrez]

Brad, I'm no expert, but if the sensor is beginning to fail on you when 
warm, it's terminal.

Replacement is not a comfortable proposition, but it's workable.  The two 
sensors are attached to an aluminum heat shield at the lower side of the 
engine on the driver's side (IIRC).  I got to them underneath.  Had to 
loosen various AC hoses and other items to gain access and even then it's a 
slow process unscrewing the mounting screws (which parenthetically seem 
excruciatingly long!), but they came out, the sensors were replaced and the 
car was back on the road, all within an hour and a half.  I personally 
replaced both while in there.  Someone with smaller hands and/or better 
tools can probably do it much faster, but it really is an unbolt, bolt up 
job--pretty easy over all.

Good luck.

Bill G.
