Well I'm about to find out. Going to open up my engine to replace the gaskets in the upper manifold as well as the isolator bolts. Might as well clean the EGR ports while I'm in there. Right now my 2001 Windstar doesn't accelerate to well and going up hills is a nightmare of backfires and stalls ... and it's easy to lose speed on inclines. In Vancouver, BC this is a problem.
I've already cleaned the MAF sensor, changed the plugs and wires, replaced the DPFE, replaced the 02 sensor in the front and checked for EGR vacuum. I'm hoping this is the final fix.

What causes a motor to backfire out of the intake manifold?
A leaking spark plug wire can cause a backfire out of the intake, but the most common cause is a burned intake valve. A burnt intake valve will allow leakage during the compression stroke back through the intake causing a popping backfire out of the intake manifold.
What is the difference between an intake manifold and an exhaust manifold?
The intake manifold is where the air and fuel mix and enter the engine. The exhaust manifold is where unspent gas and air exit the engine. In other words the intake manifold is where the engine breathes in and the exhaust manifold is how the engine exhales out.
What is a manifold leak?
A manifold leak is usually in reference to a failure of the intake manifold gasket. It can leak air, oil or coolant. It can leak to the outside of the engine or internally into the engine. A manifold leak may also refer to the Exhaust manifold that is leaking exhaust fumes from a bad gasket or a crack in the manifold.
What is the intake manifold and exhaust manifold for a 1998 Ford Escort?
Intake manifold delivers the fuel air mixture to the cylinder heads, exhaust manifold collects the gases after combustion, and channels them into the exhaust pipe.
What purpose does the manifold serve for an automobile?
On every vehicle there are two manifolds. An intake manifold and a exhaust manifold. The intake supplies fuel and air to the cylinders. The exhaust collects exhaust from those same cylinders.
How do you replace the intake manifold gasket on a 87 d100 slant 6?
remove the intake and exhaust manifolds. there are bolts that attach them onto the head and there are bolts near the carburetor that attach the intake manifold to the exhaust manifold.
On a 1987 mustang gt coolant is leaking into oil but its not the head gasket?
Intake manifold is leaking, or worse, cracked cylinder most likely tho, the intake manifold.
1986 ford f150 truck 6 backfiring through exhaust?
Intake manifold gasket may be leaking - check for loose bolts or replace fasket.
What to do with Oil leaks by manifold?
If you are talking about the EXHAUST manifold then most of the time it's the valve cover gasket that is leaking oil. REPLACE VALVE COVER GASKETS. If you are talking about the intake manifold then it has 2 rubber gaskets in the front and rear of it that leak oil real bad. If oil is on the left are right top sides of the intake manifold were the valve covers are then it will be the valve cover gaskets that are leaking oil.
What is the intake on a 1994 Chevy berretta where coolant is leaking?
Intake manifold at top of engine?
What happens to a 2001 Mercury Sable when the Manifold Gasket is unsealed?
If it is the intake manifold, there will be vacuum leaks, backfire, and poor performance. If it is the exhaust manifold, you will have loud exhaust noise which may warrant a citation - also, emissions control laws will be violated. Take the manifold ro a shop where it can be re-surfaced or try to find a product at your local auto parts store that will help seal the manifold. - Good luck.
What all can cause your truck to burn water out the exhaust?
It could just be condensation which forms in the exhaust system outside of the engine, or you could be leaking coolant into your engine (typically via the head or intake manifold gasket).
