[s-cars] Maybe it's the ECU after all

[Tom Green]

I would clear the codes and recheck after several drives to see if  
they return.  When working with the ECU, make sure you follow all the  
precautions for electronic parts and make sure you do not disconnect/ 
connect the ECU with the ignition on and wait a minimum of 30 sec  
after removing power.  I recommend that you check the security of the  
connector to the ECU and then remove it again and check the condition  
of all the pins to make sure one is not bent, etc.

You need to verify the boost line all the way from the ECU to the  
intake manifold, and the lines at the WGFV before deciding you have a  
valid code for the transducer.  There are several aftermarket  
transducers available now that have variable settings, including one  
for stock chips, so a replacement should not be expensive.
