VZ SV6 running like a pig

[auke]

I replaced all coil packs. to be on the safe side (check my earlier Post on coils Aug/sept 09 ??) $1200 and that fixed the problem.

Am going through the same problem with my 2004 VZ. Holden told me it was a vaccum purge hose....fixed that but it still missed....they said it was a coil pack....fixed that ...it still misses..now they are blaming the gas conversion because the "gas module" is causing injector no 2 problems.......they disconnected injector 2 from the gas module and made me drive around on petrol ...it still misfired on petrol..... took it to the gas guy....he checked the wiring and told me that the ECU is not sending out a pulse....am taking it back to Holden this week but they don't believe the gas mechanic's diagnosis.....this is costing me a fortune while they fix all these parts that don't actually cause the problem.

How have others dealt with this??
