It could cause the misfire, but so could a lot of other problems. The repair time is about one hour.
There are a few causes: Damaged or disconnected hoses (or component) from intake manifold. Worn out intake manifold gasket. Improper replacement of a part. Cracked or damaged intake manifold.
Your Mazda Protege might make rattling noises when parked because of a loose or damaged muffler or even body panels that are loose. It might also make a rattling noise because of a damaged motor mount.
Old/worn intake manifold gasket and/or damaged/broken/mis-routed hoses attaching to intake manifold.
It is located in the valley between the cylinders. You can loosen the throtle body, all the bolts holding the intake manifold and then lift the manifols just enough without disturbing the fuel rail to gain access from the lest side of the car to the right. This can be done with common tools and the gaskets on the manifold and TB can be reused if not damaged.
Sounds like something was droped into the engine. I would also like to know why you changed the intake gasket. If it was leaking water/ engine coolant into the cylinders then you may have damaged / broke a piston are bent a rod. Water will not compress.
Not enless it is damaged during removal
Yes. If an intake manifold gasket was not installed properly or has somehow become damaged the engine will pull air through the opening.
Nissan 300zxseveral causes,Try the simple first!Locate the cyl. off,check coilpack,spark plug,wiring to coilpack,damaged inlet manifold gasket(sucking air)Chech compression possible valve burnt out.Also possible injector malfunction.
A 2000 Mazda Protege with 1.8 DOHC engine appears to be a "free-running" engine, meaning there is no valve/piston interference in case the timing belt broke. There is enough clearance between the valve and piston, even if the cam stops (i.e. the timing belt breaks) with the valve fully open. Therefore, the car will not be damaged if the timing belt broke.
One or more of your cylinders are not holding their seal. Worn out piston rings, worn/damaged piston, worn/damaged cylinder wall are the most likely problem areas.
Among other reasons, a pulley or a belt might be broken/damaged.
check the compression on all cylinders make sure they're all within a couple of pounds of each other at least 125lbs.
