Pressure Sensor

[John Clift <jclift@deans.umd.edu>]

Hi,
Anyone know what a Manifold Pressure sensor costs? Mine is for a 71 FI 
motor, the number on the sensor says 030.  I tested the pins with a ohm 
meter, two outer pins 7&15 read 100 ohms, two inner pin 8&10 read 350ohms.
I tweaked the little screw at the end and now can't remember how it's 
supposed to be set. OOps. It runs like before but now it runs rich, smoky.
The main prob still exists; loses power on hills. Could it still be the 
man. pres. sensor? I'm at wit's end here as this prob has persisted for a 
year. Two wasted trips to Reiner VW and one to Sartwell have proven 
futile. At least Sartwell got it to run smooth again. Rainer didnt even 
do THAT and said 'oh car runs fine now'. He couldnt have meant MY car.
I need this car to run perfect, I am driving to Los Angeles then Seattle 
soon but all will be bust if I cant get car fixed. 
I have had this Fastback ten years and swear by it. I dont want to let 
one quirk ruin an otherwise fine car.
Car has 179K miles, motor and trans have 9K miles. If anyone in Wash DC 
area is an expert, Im a paying customer.
Frustrated isnt the word.
