wierd idle issue on startup after valve cover gasket replacement
So after the gaskets were replaced the next morning I start the truck up and it sounds great.. head back in to make my coffee and I hear it revving up.. so I run out and it was reving up to about 2400 rpm then down to 1700ish.. once it warms up it stops and no other weird issues at all.. im thinking a vacuum leak somewhere? But wouldent that show issues throughout the rpm range and not just at cold start ups?
