Air filter replacement

If all bolts have been removed all thats left is to pull the air filter housing off, it may be stuck a little bit if its been on there a while, just put a little muscle in to it ;) note* make sure all bolts and clips have been removed before removing housing

Please let us know if you need anything else to get the problem fixed.

The cover of the air cleaner housing usually has four clips that you unlatch and then you can lift it up and out of the way. If you are sure you need one tell the parts store your engine size and the new filter has instructions, or the person will be glad to show you how it is done, then you'll be on the way to maintaining your minivan properly. Good for you.

2000 Dodge Caravan High Hydrocarbons

Hydrocarbon failures mean unburned gasoline is passing through the engine and entering the exhaust. The three most common causes include ignition misfire, lean misfire and low compression (typically a burned exhaust valve). Ignition misfire can be caused by worn or fouled spark plugs, bad plug wires or a weak coil. Lean misfire results where there is too much air and not enough fuel, so check for vacuum leaks, dirty injectors or a fuel delivery problem. In addition to these, hydrocarbon failures can also be caused by oil burning due to worn valve guides, valve guide seals and/or rings.

You need to slide the assembly up and out. I believe there is only one screw at the top that holds it to the rad support. Remove that and lift it up. From there, I believe it is clipped shut. Check out the images (Below). Please let us know if you need anything else to get the problem fixed.

Tia, do you have a check engine light? If yes, I would need to know what code # and the description. My first thought is a gross vacuum leak. You want to check all your vavuum hoses for splits or disconnects, especially around the transmission area. Hope this helps.

My first suspect would be the idle air control motor IAC. It's mounted on the throttle body unit. This little unit's main purpose in life is to control the engine idle speeds to compensate for AC, power steering, cold fast idle, etc. It may just be carboned up and just need cleaning. This can be done by removing the unit and spraying it down with an ordinary can of carb cleaner. Hope this helps.

One more simple thing to not overlook. You didn't say how long ago or how many miles since the rebuild. They would have disconnected the battery. After that, minimum idle must be relearned by the engine computer. Until this is done, the computer doesn't know when you have your foot on the gas pedal and when it must be in control of idle speed.

It knows your foot is off the pedal when you're coasting. The strategy it uses is higher than normal manifold vacuum for seven seconds. High vacuum will occur if you snap the throttle open and closed real fast, but not for seven seconds. You have to coast down from highway speed for the high vacuum to occur for seven seconds or longer.

When these conditions are met, the engine computer looks at the voltage from the throttle position sensor and puts that in memory. The next time it sees that same value, it knows it has to control idle speed.

Most technicians will perform a test drive specifically to prevent this customer complaint after doing any work that requires disconnecting the battery.

You may have met the relearn conditions by now, but introduced another problem by just changing a bunch of parts without diagnosing the problem first. Specifically, by throwing a throttle position sensor on it, the sensor voltage at idle will be different than before, possibly by only a few hundredths of a volt. If the computer ever sees a voltage lower than before, it will put that into memory, but if it never goes down to the voltage it saw with the old sensor, it assumes you are holding your foot on the gas pedal so it lets you control idle speed.

There could be a lot of other causes of erratic idle, but expect to have to just drive the vehicle if the battery is disconnected again.

You'll need to find out the engine size, it's on a decal under the hood, usually right on the underside of the hood. If you can't find it get the VIN number off the dash pad, its located on the left front where the windshield meets the dash pad. When you bring it home you'll see the size, it is under a black cover that runs from the air intake to the air cleaner box or housing as it is referred to. It will have metal clips or plastic screws that hold the lid on, you can just unclip it and bring it up by bending the rubber air hose it is attached to. The old one just lifts out and put the new one in the same way. If your not sure look in the section on how to replace iot here.

REMOVAL

1. Remove 2 screws and air inlet resonator (Fig. 125).
2. Loosen 3 clamps holding air cleaner housing halves together.

4. Remove element from air cleaner housing (Fig. 127).

INSTALLATION

1. Install a new element in housing.
2. Position left side of housing.
3. Snap clamps into place.
4. Install hoses and air inlet resonator.
There is your instruction's i have never seen a orange air filter element maybe you mean a orange border air filter.I would just get a fram one there really good.
