Welcome - just use the search tool at the top of the page and look for CLEAN MAF - there are several posting about it, but make sure to heed the warnings about NOT TOUCHING the internals.

And it's best to use a cleaning spray specifically made for cleaning the MAF.

I just got around to moving this thread, so look at the date before posting.

Yeah, the OP was a "one and done" poster. Never to return.(at least not since Oct.)
