Generally this is due to carbon build up on the throttle body butterfly. Carbon builds around the bore of the throttle body and the airflow is difficult for the engine control module to control.
Take the rubber boot off of the throttle body (it's held on with a hose clamp with a screw that can be loosened with either a philips head screwdriver or 7mm socket) and use carburetor cleaner and a rag to clean the throttle plate and the bore that it sits in. To make this easier, remove the coolant resevoir (3 phiips head screws). Just disconnect the connector on the bottom of the resevoir, don't disconnect any hoses.
When you are done, turn the key to on, don't start the car, and press the gas pedal to the floor and hold it there for 5 seconds. This helps the ECM learn the range of the throttle plate.
You should have this all fixed up for under 5 bucks.
it may be the pcv valve ( positive crankcase ventilation) that needs replaced. if a pcv valve fails, it will put oil in air cleaner or throttle body. check to be sure hose to valve is not clogged up. its only about a 5.00 part. have a good one !!
Looks like gum and carbon deposits have clogged some critical parts in the engine, such as injectors.
You would need to get to the 'throttle-body'.
1. Trace the big intake-air hose to where it ends on top of the engine. This is the throttle -body.
2. Loosen the clamp that's holding the big-intake air hose. Pull off the intake air hose from the throttle-body.
3. Spray some "Throttle Body & Carburettor cleaner into the throttle-body. You could use the entire can.
4. Wipe off excess gas from the throttle-body with a piece of rag.
5. Reconnect the intake air hose, and check if the
problem has disappeared.
First, have your daughter listen for vacuum leaks (young females generally have the best high frequency hearing) They will sound like a very high pitched whistle. Next, look for vacuum hoses that are damaged and leaking. Next, clean the throttle body. Remove the hose that goes from the air cleaner to the throttle body. Hold the throttle plate open and spray some throttle body cleaner (available at an auto parts store) in and scrub with an old toothbrush -- don't forget the top. There are other things, but these are the easy, common, obvious first tries.
the best way to find a vacuum leak is to buy throttle body cleaner as it is combustible, if you spray around the hoses and manifold base and you see that the engine idle goes up or down you have found you vacuum leak. a lot of times on old cars, the hoses start deteriorating with age and heat.
it soubds like you have a vacum leak problem listen for a "his" with the engine running. you may want to take apiece of hose @2-3ft long put one end at you ear and probe arround the top of the engine arrount the intake manafold and any hoses when you find the his find wher it goes and replace repair the hose. it may also be your pcvvalve thst is stuck it willcome out of the top of your valve cover and plug right the intake hose right before the throttle body
have you checked for vacuum leaks? thought mine was spark plugs and found broken vacuum hose attatchment behind throttle body to manifold was broken... that was my problem, maybe yours too? It's the hose just behind throttle body on passenger side- mine was a broken rubber elbow right at top of manifold- it's reachable without taking throttle body off...
First look for a vacuum leak in all the vacuum hoses leading to the throttle body and on the intake manifold itself. Sometimes it helps to use a piece of hose as a makeshift stethoscope to listen for tell-tale hissing at the site of a leak. If no leaks are found the problem could lie in a faulty idle air control valve
