Yes, while the engine is running (in park) spray gumout/carb cleaner along the egdes of the intake. If the motor runs smoother or better then that tells you the intake is leaking. This, however, could cause a fire. A safer way is to use an unlighted propane torch. Turn the fuel on low and slowly move it along the hoses and gasket surfaces. When the engine speeds up, you have found your leak. if you are not sure if there is a leak in the intake ;a good way is when the engine is at idel carefuly place a rag over the carb or throttle body slowley closing the opening ( hold the rag tightly )while slowley placing the rag over the intaks ; if you notice an increase in RPM then you probley have a vacumm leak; to help pin point the leak use a spray with water and slowley go around the base of the carb ;manifold and vacuum lines when the RPM'S increase check that area for leaks ; cracked vacuum lines ;intake gaskets leaking this should help
IDLE CONTROL VALVE GONE BAD Check for vacuum leaks. In particular check for leaks in the PVC valve hoses. Follow the rigid line from the PVC valve (top of right rocker cover)back to a rubber TEE at the right rear corner of the intake manifold then follow the line from the TEE across to a rubber ELBOW on the left corner of the intake manifold. Check both the rubber TEE and ELBOW for ruptures that will allow for a vacuum leak.
It has been my experience that most backfiring problems are cause by intake vacuum leaks. You might want to check the torque on the intake manifold retaining bolts or it may be a worn intake manifold gasket. You might also want to inspect the vacuum hoses for cracks or loose connections. You might also check the timing. If the timing is off, it can also cause backfire and starting problems.
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.
check spark plugs cap and rotor, and ignition coil. check gaps on spark plugs.checkfor blue fire getting through plug wires.ifso check egrvalve could be stuck open. check for intake manifold leaks. if egris good and no leaks are found check fuel pressure from pump. if fuel pump and filter are good check each injector for operation. they should open when interjized.
