Hi,
If you have any experience or knowledge and have a few minutes to spare, please have a read below?
4200 CC 2003
Car and engine very well looked after in previous home.
Car ran out of petrol and was left sat for 6 months in between last owner and us.
Starts instantly and sounds great and then as the revs increase, the misfiring starts.
Mis-firing Error codes are P0300, P0301, P0302, P0303
New spark plugs, same error codes.
Coils checked and swapped to opposite bank, same error codes
Faulty O2 sensor replaced, same error codes
Same 'pressure' from both exhausts (Non standard exhausts with no pre cats)
MAF lead connector cleaned and slightly better but still misfiring, same error codes.
The next steps are fuel rails and smoke test.
Is there anything else we should be thinking about?
Thanks
