Intake Air temp sensor (cont'd)

I had an intermittent Intake Temp Sensor problem for ages.  I checked  
the continuity a number of times at both the connection itself and  
inside the car at the ECU connection.  Every time it checked out fine  
and the connection itself appeared to be in good condition.

I finally broke down and went for the repair of the connection a  
couple of years ago using the dealer available gold connecters.  It's  
been fine ever since.  For me, the hard part was making the solder  
connection and covering it with heat shrink tubing between the new  
connectors and the existing wiring, and leaving the correct amount of  
wire so the existing rubber boot fits right back the way it is.

So for my money, the dealer connectors are a good solution.
