SO my mechanic wants to charge me $700 cuz he thinks its the lower intake manifold gasket... I looked for vacuum leaks and I didn't find any. If I needed the gasket, would it be doing that all the time instead of on boost. and now I notice that it runs fine above 4000 rpm. It only happens when its going into decent boost between 2000-4000 rpm. Im going to try to do the fuel filter, spark plugs and wires and see if that does anything. is there anything else that is cheap that I should be taking a look at b4 I use this gasket as the last resort?
