Highly possible brake booster has,failed. You can pinch off the vacuum line and press on the brakes if idle does not change ,replace booster,if idle still changes take to a mechanic. Do not attempt to drive it with line pinched

SOURCE: Where is the fule filter located on a 1997 Kia

Following the fuel line is always the way to find the filter. It is just forward of the passenger side rear wheel. It is connected to three lines with quick disconnect fittings. You don't need any special tools to remove them, just push in the flat buttons on either side of the connectors. When you put the lines back on, just push them on firmly, and then check to see if they are all the way on by pulling them as if to remove them again. Good luck and hope this helps.

SOURCE: Fiat Uno Pacer - Brake Booster not assist braking

it could be that the master cylinder is bad or the brake booster is bad also check the vacum hose going to the brake booster if it has a hole in it it will lose pressure and make the engine lose rpms

SOURCE: The idle has an intermittant stumble

Your Idle Air Control (IAC) valve may be dirty with carbon, simple fix with throttle body cleaner through the IAC passageway through the throttle body. Make sure it's throttle body cleaner and not carburetor cleaner, the carb cleaner is to corrosive to the gaskets used on the throttle body.
If cleaning the IAC does not help, then it's a good chance that the IAC is to far gone and will need to be replaced.
Good luck and thank you for using fixya

I HAVE KIA SEPHIA THE RPM DROP AND GOES UP Suddenly


Engine stall or RPM fluctuates at idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

No you may have a dirty idle speed control valve. Follow the instructions below to clean it.

Thank you for help my kia sephia 1995 problem is that the engine speed decrease when start the AC knowing that the engine idle speed is 850 rpm.


Hi, Check the a/c diaphragm idle up! Must be the vacuum line is disconnected or there is a leak in the hose, and the diaphragm itself is not working anymore! Maybe needs adjustment!
hope that helps u out!

I am pretty sure but not 100% that this holds 4 in the pan and 1 in the filter. 5 total. Also check on the side of the open drivers door for specs. It is sometimes located there with other information. I hope i can count on a good thumbs up for the try, Raz

2000 kia sephia constant engine stalling!!!


try this procedure and let me know if it cures the problem.

Here is the common cause of surges, 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.
