Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
I've seen this too many times to count.
Have the injectors been serviced off car?
Have the intake valves been cleaned with upper cylinder cleaner?
How many kms on this car now?
Too high in octane, what a load of rubbish, makes no difference.
Do you need any further help?
I hope my advice has been of assistance to you.
