I’m decarbing the intake this weekend. I’m not finding a clear way to rotate the cam to ensure closed valves as I progress through the cylinders. Some say turn the alternator but that may throw off the timing. Is this correct? What’s the best method?

Hello,

is there anyone here who has done cleaning the throttle body and intake valve before?

I have already bought "CRC intake cleaner" from REPCO.

They told me that it must be sprayed to avoid a MAF (mass air flow) sensor.

But I couldn't...
