1994 ford ranger has chirping noise coming from behind motor I replaced distributor cap and rotor still happens and i can't figure out what it is does any one know?


Sometimes this is called an Exhaust chirp. This can happen where the main exhaust pipe meets the exhaust manifold. There can be a part called an exhaust donut, which is in between the manifold and the catalytic pipe.

Some models have a smaller pipe coming from the catalytic pipes and approaching the Pollution equipment. Some of these pipes have a flexible joint which rusts and leaks causing a chirping noise.

    WHAT IS A PLENUM


    a plenum is the top part of the intake manifold, modern fuel injected cars and trucks (gas engiones) have a upper and lower intake manifold, the upper section is called the plenum.

    Toyota 1988 camry


    Egr Valve is usually attached to plenum with a tube that runs to exhaust minifold. If you dont know what those things are then. Find the black tube that runs from the front of the car to the front of the motor. there should be a big square box where you air filter goes in the middle of that tube. Well where that tube connect on the front of the motor. That is called the throttle body. the big block of aluminum is called the plenum. Bolted to that plenum is going to be a space ship looking thing that has one rubber hose a wireing plug that plugs into it and a long tube that is attached to the bottom that goes down behind the motor to your exhaust. There should be 2 or three nuts or bolts that hold it in place. Sorry if I overexplained this but I do not know how much you know about the car......Good luck!
