It was incredibly helpful.
Certainly in my M20B25 is much easier to access all parts of admission without having to remove the intake manifold.
Anyway they took me almost a month to do all the work of cleaning and maintenance.
I work for an activity a week to test the difference between a repair and another.
I went outside to the inside.
First change of air filter and clean the intake pipe and filter box
The following week I did the cleaning and change of thermistor flowmeter that goes into the basket in the pipeline.
A week later, i made a rejuvenation of the flowmeter, another DYI thanks tp Fede318i a friend from Argentina troght bme30.org.
3 days after, i clean the idle control valve (ICV), as described here, in this DIY.
In this part, use isopropyl alcohol, SONAX contact cleaner and 3M lubricant.

I must say that the changes were significantly positive for my old M20.
I am very happy now.
greetings and thank you very much Dudesky
