I suggest that you purchase MAF cleaner and liberally spray the sensor which are the wires that are not as obvious. Most of the time cleaning the MAF will solve the problem if that is the problem. It is an easy one to eliminate yourself. As far as other causes, there are many possibilities. In the major of cases reading codes and troubleshooting will get you to the core cause faster and less expensive than throwing parts at it. An example of some other possible causes----vacuum leak, fuel pump, gas filter--the list goes on.
Thanks for the advice - I've asked around a few local shops here and they don't sell specific sensor cleaner and the mechanics seem to not have tried this but looking on the internet it appears a common thing to do and it makes perfect sense to me to even do it regularly anyway to make sure it is sensing correctly. I have ordered some CRC MAF sensor cleaner to be delivered so will check it out visually first then spray with cleaner when it arrives.
