I was toying around under the hood and wanted to pull the MAF sensor to clean it... but after removing the fasteners... the sensor did not want to come apart from the intake hose... It came up a lil but then stopped... I certainly do not want to damage it.. Anyone else had this issue? do I just need a lil more elbow grease? Or is there some sort of clamp or what not inside the intake tube I need to release.
