Ok hi all my mech says i need a new upper and lower intake gasket, car is shaking , no cel yet , so is it air that's leaking , cause car isn't leaking any fluids, # 2 plug gets fould every few months, , but im thinking it just needs a tune up,:: Has new wires ,and coil , any one else know what it could be?
One way to check and see is this,
Get a can of brake clean and spray it along the edges of the intake where it meets the head. If an air leak is present the engine will drop in rpms and idle rough. It won't harm your engine at all; it will only last a few seconds. It's one method we use at the shop where I work at.
Many seek good nights and loose good days...
