"When I remove the oil filler cap the motor starts idling funny, rises falls and sputters very sporadically."
Cool, not for you, but for me. That is what mine is doing at idle which makes me think I have a vacuum leak not the MAF. I will order in and replace the oil filler tube, get a new oil cap and continue to look for vacuum leaks, any ideas for other leak points would be appreciated.
