So I purchased a more expensive Bosch MAF sensor and housing. While waiting for it to arrive from USA to Brisbane I decided to give the cleaner a go. There were two popular cleaners on the shelf. I figure I am just testing so I purchased the smaller one (see photo).
Next I removed the clips off the air filter box lid, unscrewed the hose clip around the maf and noticed the top of the filter was greasy. Then it dawned on me. Its funny how you dont put things together first off. The last mechanic had left one of the clips undone. In fact it was on backwards (duh) and I remember lifting the bonnet and seeing the gap to the filter and thought that was poor workmanship. Have a look at the filter (photo).
Anyway, I did the clean and put it all back together and at the same time ordered a new air filter. I drove around a bit with my fingers crossed hoping the dirty filter will not cause the issue again and then nothing. No problems. The new air filter arrived and I was so glad to swap it over. I haven’t had an issue since. The new bosch MAF sensor arrived from USA and I have placed it on the shelf just in case for the future. But I think I will do a regular clean of the MAF sensor every 6 months.
Now onto the next issue. 🤓
