Re: Cleaning MAF Sensor? (JCR)
I clean mine with electrical contact cleaner from Radio Shack and a Q-tip.
I have a Halltech TRIC and clean the wires every other re-oil.
It's easy to do. Just be gentle with the Q-tip.

Re: Cleaning MAF Sensor? (stevenll)
What will be the effects I can feel during driving, when the MAF is covered with filter oil? Could it produce pinging on decent accelerating in 4th gear auto?
I have the Blackwing for 15 kmiles now and never cleaned MAF. Is it time to clean it?

No hurry Frederik,as you are not having any problems. The next time you have it apart (or feel like a new project) do as they did above, with contact cleaner and a Q-tip..... very carefully. :yesnod: :)

Re: Cleaning MAF Sensor? (C5 Frederik)
Frederick,
If the MAF sensors have some kind of contaminant on the wires, the MAF translates that as less air flow than the engine is actually getting because the sensor wires are insulated from the air flow. This will naturally cause the engine to go lean, even as the rest of the fuel system is trying to compensate. Voila, there's your pinging.
So, if you're coming up against a detonation issue, I'd clean the MAF first, it's just too easy to do, and it eliminates one variable.
HTH, and have a good one,
Mike

I would not use a q-tip.. one slip and you brak one of those wires and your out 400 dollars... CRC contact cleaner, or radio shack contact cleaner spray are all you need...

Re: Cleaning MAF Sensor? (JCR)
We once fought a custom electronic F-I, supercharged install only to find we had once sucked in some oil into the sensor via a misplaced crankcase vent line. Cleaned the MAF and it made all the difference in the world.
Check that the contact cleaner doesn't have a "lubricant." One I've seen at RadioShack does.
All the best. :yesnod:
