After market part are prone to fail quicker than original parts. it can also be a dirty idler and may just need cleaning power problems can be related to another problem. blocked breather or blocked air lines. timing related problem spark plugs would need to be removed and check for there color. they should be a clean colour black or brown is un burnt fuel. sensor fail cam or crank. you would need to have the ecu read to find out more.

Please explain your problem in queens english as it doesnt make sense to me sorry to sound rude but its taking a long time to try to interpretate!like are you refering to the air filter ? please remember this car is 21 yrs old and as far as our europeon models are concerned thses car would have reached the scrapyard many years ago owing to the yearly mechancial inspection that a vehcile legally has to have when over three years of age .This inspection clears most cars over 10 yrs of age from the roads due to corrosion and emmisions failures .

SOURCE: Car rev up and down at startup, also car jerks at release of gas

This sounds like a vacuum control problem. Since part of the problem is when the engine is cold; a thermal switch is venting vacuum until the engine warms up enough to shut down the thermal switch, thus restoring a steady idle. Vacuum can be affecting high rpms while running too. You could have a misrouted EGR vacuum line opening the valve at the wrong time. There are sometimes hose routing decals on the radiator shroud or under the hood. These can be visibly checked.

SOURCE: High idle speed when the engine is cold

The high idle speed at start up is normal. As the engine temperature increases, the engine idle should kick down automatically. Insofar as the emissions results, if there were a problem, the check engine light should be on. If it is, take the car to an autoparts store and have the fault codes read. Most parts stores will perform the scan for free. If the check engine light is not on, and the idle question was all you were worried about, you are good to go! Hope this helped and best wishes.

Here are the most common causes of idle surge, rough idle esp when cold and stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Manifold pressure sensor.l
your idle is too low? what is it cold and hot.
you have a gross air leak (vacuum) to the intake plenum
the sensors , almost never fail. it also wastes fuel like this.

Engine misses when idling at 800 RPM when warmed up


The idler air control is not working like it should. try tapping on it with a screw driver lightly this should kinda fix the problem while u are tapping. This will need to be replaced if it starts agian after u stop tapping.

Honda civic hatchback idles really high


The person that told u that it was the tps and idle air they we're completely right!! The tps sensor is what makes it do that. If you pull the air intake of there's 2 holes on the throttle body. Plug one of the off with your finger while the engine is idling high and it should come down mine was the top hole. If it does go down just get a new tps sensor. and the back sensor on the intake to be safe. or the ghetto way is to plug the hole off, not my sugestion.

1991 Honda del Sol Overheating and funny idle


The idle problem kinda sounds like the IAC (Idle Air Control) valve on the intake manifold. Another idea is maybe coolant temp. sensor. And if it's leakings coolant still after replacing all those parts then i would say maybe the water pump is leaking since i believe on those motors its by the timing belt which is behind the plastic cover on the motor so maybe that's why you're not seeing fluid so much because it's in there. Hope some of this helpes, good luck.
