All of this suggests bad sensors. I would check the engine codes and try again!

It may me the Transmission Modulator Value.
a small diaphram value that measures pressure and tells the transmission when to change gears. If the diaphram is leaking it never can measure the right pressure. its on the transmission housing. Just disconnect and screw it out.

I have a Kia Rio 2005 Cinco( 5 door) Running really rough until I push down gas pedal,,, Then it seems lOk still a little r bogged down', It doesn't stall just runs rough without accelerration? Oxyg


To begin with, is your "check engine (CE)" light on? If it was on and now its not, you need to replace the bulb. If CE lights is on, find out the codes before doing anything. If bulb is good and "CE" does not come on, begin with: (1) gapping spark plugs, (2) replace spark plug wires (if haven't changed them within the last 2), then the coil. If your Cinco is still idles rough, adjust gas pedal until idling smoothly. If this still doesn't help, replace your two oxygen sensors. If still running rough, the converter. After doing all this and problem is still present, take it to a mechanic you trust.

Check the CO/Temp sensor in the exhaust manifold. It may tell the ECU that the engine is hot when it is cold or cold when hot, getting the mixture wrong.

Rough idle, check engine light on. Kia Rio 1.6 L 2005


Could be many things but it sounds like your idle air control valve. It should be on top of the throttle body. I'm not sure on this vehicle. It is a accordian like diaphragm in a housing, They get clogged with carbon. Usually attached with 2 bolts and a sensor connector. Easily cleaned out with carb. cleaner. This will throw a code if the diaphragm is letting too much or too little air in to the fuel mixture. It may also be a vacuum leak. You can spray very short burst of ether around the intake manifold, if the engine races you have a vacuum leak. I have never had a fire but have always had a fire extinquisher within reach . USE COMMON SENSE.
Good luck. p.s. DON'T SMOKE AND KEEP CHILDREN AWAY!

2002 kia rio stalls when coming to a stop if the gas is not applied


My personnel fix for this.

Here are some of the causes 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.
