Question about 1989 Plymouth Acclaim

1989 Plynouth Acclaim. What is the hose that runs out of the bottom of the air filter assembly to above the oxygen sensor/manifold area in the engine. Where that hose attaches is all rotted out and I

This part has a metal hose that goes from under the carb. and above the oxygen/sensor/manifold area. It connects to the air filter assembly on the bottom. I need that hose and the piece that is on the engine as mine is all rusted/rotted out.

    I actually found it. Autozone has a diagram. It is the Air Heater Connector that goes from the Fresh Air Intake of the Air fileter asassembly to the Intake Manifold. My Intake Manifold is all rotted out. Looks like it's junkyard search time.

    No one mentioned that besides the hose, the INTAKE MANIFOLD that hose connects to is what is also rotted out. I stated that whole place where it attaches is rotted out. Autozone has a helpful online manual to remove the intake manifold. I am pretty sure I can get that hose from someplace like RockAuto. I am not in Colorado. Our server is, and thanks but this car is so old it's not going to a mechanic. I'll fix it myself. Car's only worth about $800. Thanks for the info though

Sounds like you are talking about the heater hose that provides hot air from the exhaust manifold. It may still be available from the dealer.

Testimonial: "The exhaust manifold where that hose attaches is rotted away, could this be causing the engine to run very poorly, it barely will idle and I can hear air sucking."

SOURCE: sensors for vw golf?

MAF sensor is located between air filter & air intake on engine, its in a plastic housing in the middle of the rubber hoses. BE CAREFUL THIS IS A DELICATE & EXPENSIVE COMPONENT.
MAP sensor is located on hose outlet from intercooler on the offside of the engine near the wing. AGAIN,, BE CAREFUL, DELICATE COMPONENT

themoneypitt did just fine,except it's not a gasket,it is a O-ring.
At least it is on the 1995 Acclaim.

Use the following diagram to determine the configuration of your heater hoses. It is from 1992 Caravan manuals from Dodge. Hope this helps.

SOURCE: Oil leaking from the gasket on the metal piece under oil fltr

Make sure that the oil filter is tight. Usually they only leak if dirt was in the gasket when the filter was installed or the filter wasn't tightened enough.

You could find sheets of gasket material in well-stocked autoparts stores. They are water proof, and you could make one yourself that should solve the gasket leaking problem.
Once you find a sheet, try and make a stencil from the top of the manifold, then cut it out with a good scissors.

How do I fix a vacum leak on 2002 nissam sentra gxe

You have to find the leak and seal it up, hey. It may help to picture where vacuum originates in the engine: As the pistons move down in the cylinders they pull air in from the intake manifold. This creates a pressure drop in the intake, a vacuum that is maintained as the engine is running. New air that is pulled into the intake is measured by the Mass Air Flow sensor mounted in the big boot between the air filter and the intake. If extra air is pulled into the intake manifold from a vacuum leak, uncalibrated air, the computer can figure it out from the oxygen sensors reading in the exhaust-mixture is too lean, so the computer will try to compensate by delivering more fuel, but can't deliver enough, mix is still too lean, so computer sets a code for the vacuum leak.
The intake will have a few vacuum taps with hoses running to engine or car controls that require vacuum to operate. If one of the hoses comes off or has a leak, that is extra air into the intake. Your power brake booster has a large vacuum tap. That may be the problem. With the engine running, pull off that line and plug it, and see if engine speed changes. If the idle drops that may be your leak-a failed power brake booster.
If nothing yet, keep engine running and spray some starting fluid around the mounting area of the intake manifold (maybe the intake gasket has failed and sprung a leak) and listen for a change in engine pitch or speed. The fluid may get sucked into the intake and cause speed to change. If it does, you would need to remove the intake manifold and fit a new manifold gasket.
Also check the big boot from the air filter to the throttle body for tears or loose fit. Good luck, Rev!

My car burns gas very fast. where is the 02 sensor located? do i need a calib cabreter?

02 sensors are located in the exhaust the upstream ones are close to the engine in the rear exhaust manifold (for 6 cylinders) and at the front exhaust (for 4 cylinder). The downstream ones are behind the catalytic converter. Check to make sure the fuel pressure regulator on the to of the engine isn't leaking. Replace the air and fuel filter could be plugged. Check the coolant level in both the rad and the reservoir they are notorious for intake manifold and head gasket leaks for 6 cylinders. There aren't many calibration updates for this vehicle relating to fuel consumption.

2001 ford taurus 3.0(2) codepo174, changed oxygen sensors and fuel filter code still comes up on memory

This code is usually caused by leaking intake manifold gasket on the front side. With the engine running, spray carb cleaner or ether on the gaskets. If the engine revs at all, you have a leaky gasket. If not, check for other vacuum leaks in anything attached to that side of the manifold. If you have more questions, please let me know.

Change oxygen sensor

Under hood, center, front engine area, above exhaust pipe flange, mounted in exhaust manifold
Under hood, center, rear engine area, above exhaust pipe flange, mounted in exhaust manifold

The oxygen sensor may be difficult to remove when the engine temperature is below 120°F (48°C). Excessive force may damage the threads in the exhaust manifold of exhaust pipe.
  1. Start the engine and let it warm up to 120°F (48°C), stop the engine and disconnect the negative battery cable.
  2. Detach the electrical connector from the oxygen sensor.
  3. Using a special, oxygen sensor socket, remove the oxygen sensor from the exhaust manifold or exhaust pipe.

NOTE A special anti-seize compound is used on the oxygen sensor threads. The compound consists of liquid graphite and glass beads. The graphite will burn away, but the glass beads will remain, making the sensor easier to remove. New or service sensors will already have the compound applied to the threads. If an oxygen sensor is removed from the engine and if for any reason, it is to be reinstalled, the threads must have this anti-seize compound applied before installation.
  1. Coat the threads of the oxygen sensor with anti-seize compound 5613695 or equivalent.
  2. Install the sensor and tighten it to 30 ft. lbs. (40 Nm).
  3. Reattach the electrical connector to the sensor and the negative battery cable.

Very,very heavy on gas

Change the air filter, the fuel filter, and your oxygen sensors (the oxygen sensors are the main sensor used to compute the air/fuel mixture going into your engine). Also, check and adjust your tire pressures. On your car you should run about 36psi in each tire. Low pressure will kill your gas mileage.

95 honda accord dx with 2.2 non vtec won't stay running. Checked the ignition switch and main fuel relay. Changed fuel pump and filter. I am getting fuel to the fuel rail but the engine isn't getting gas....

You say you checked the ignition switch, you are 100% sure that isn't the problem? this year and indeed most 1990's Honda"s has a problem with the electrical contacts in the ignition starter switch, the symptom is the car will run until the key is released to the run position or the engine just stalls for no reason, the switch is very easy to replace and I bet is your problem, just remove the sterring column covers, they are a **** shell cover the screws are recessed on the bottom of the cover, Honda doesn't sell the switch seperately from the key cylinder buy it is sold in the after market, here is a price and picture of the part.
