MAF Sensor and Throttle body removal how to

Thanks Matt for sharing the link on the other thread. I'm waiting for mine, and as per "alternative parts" thread, this code goes for the following:
Bosch 0280218084
Maserati/Ferrari 180045
Fiat/IVECO 504074171

Quick question: If someone wants to clean the throttle body, do we use the same spray as Miles mentioned?

I'm inclined to use the 'if it aint broke don't try and fix it' on throttle bodies Nikos, those sprays often drive the dirt further in. I would tend to limit it to wiping with a petrol soaked cloth. That will shift most grime.

I am surprised that you guys take the risk of cleaning the MAF. Here, engineers avoid to clean the MAF, as they tend to get worse. Throttle bodies are cleaned though. On the saab (10years of ownership with 380000 kms) i cleaned the throttle with spray every 10k. And it run great until i sold it.

I changed mine as I had hot starting issues, it made no difference what so ever.
