I removed the battery off my mb6 then put back and now when idle the revs are going from 1k to 2k then back to 1k then 2k and so on. I've cleaned the idle air control valve, cleaned throttle body, put new coolant in, sprayed wd40 over the hoses to find vacuum leak but nothing so far. Noticed a leak from inlet manifold gasket, would that be related to idle issue? Car is also running lean, I've ordered new plugs and fuel filter to see if that helps.
