2007 Nissan Altima Q&A
2007 Nissan Altima Question: Have a random misfire now that was once showing up as cylinder 1 and 3 misfire.
Changed plugs with oe plugs and moved coil packs around to see if misfire would move to different cylinder. Same results. Changing intake gaskets now because read a lot of people say that was the issue. Never had this bad of an misfire due to a intake leak but thought for the 20$ gasket set what the hell. Worried that its not gonna fix my issue. - hunter1984
Engine at idle, spray a little wd-40 with the straw attached directly onto intake where suspected leak is to see if it smooths out. If so then gasket is leaking, if not need to test further for source of misfire. - pushrod
