Ignition system problem?
Ok so I'm in the midst of purchasing a 2006 G6 GTP Black on Black (leather), 6 speed manual tranny, 3.9L engine.
I had it inspected yesterday at a CAA station (Canadian equivalent of AAA). I had its compression tested and engine systems verified ontop of the regular inspection.
The results stated that the starting, charging, compression, fuel emissions and cooling systems were all great. But the ignition system had a problem here are the problems:
One problem said
Diagnosis: too few coil oscillations
Probable cause: defective ignition coils
then there was some spark plug problems - hinting that the car was in need of a tune up (57,000 KMs on it)
My question is it possible that this is a false positive? Let me explain - I saw the technician program the computer before running the tests - he told the computer it was a 2004 Grand Prix 3.8L engine (I dont think it had the g6 in the software) but could it have detected this problem due to the VVT or something?
