Question about Kia Cars & Trucks

Idle speed for Kia Rio 2007 is 1600 RPM. How do I reduce this to normal 750-800 RPM?

The motor was rebuilt due to overheated. Cylinder head was re-faced and pressure test before re-installation. Timing is perfectly done and starts fine, however idle speed is too high at 1600 RPM. How do I reduce this to normal 750-800 RPM?

SOURCE: idle at 1500 to 2000 rpm

Most likely the throttle body gasket (between the throttle body and the intake manifold) is leaking.

SOURCE: engine stalls after cold start-up & release from high speed idle

I had a similar problem.  I found the filter cartridge below the pcv valve had carboned up, and after the crank case pressurized, oil was forced out the pcv supply line to the throttle body.  The idle air control valve solenoid got oil in it and caused my problem, but only when it was cold.  The pcv cartridge is accessed by removing the pcv valve and the rubber fitting that the pcv valve mounts in.  It can then be fished out with a pick set, and it is a pain because you can't see it, but you can get you hand back there.  I hope this helps you.

Check your Ignition timing before anything
check your plugs see what color they are
red or orange means carb is to lean , black
or oil means to rich then you can go from there
and set mixture screws on carb , let me no how you make out .

SOURCE: 2002 Kia Rio runs rough when idling

well spend some change and have a simple tune-up.  Plugs and filters and readjust the idle.

2003 nissan frontier stalls when i slam on the brakes


Check oil level, but might be idle motor going bad. The idle motor kicks down the idle as needed as the rpm dictates. If sudden reduction in rpm occurs the idle motor normally keeps up and motor continues running at reduced idle. Unless its going out on you, then you may experience stalling when speed is suddenly reduced such as hard braking.

Engine overheating 2004 kia rio changed thermostat, lots of antifreeze, still overheating


Then the problem is the water pump or a cracked Head, blown head gasket or cracked cylinder wall causing over pressure in the cooling system. Replace the water pump first then consider the other problems. If you do a compression check and have compression on all cylinders but extremely high compression on 1 or 2 then the problem is the Head gasket, head or Cylinder wall being cracked.

Kia Rio died in traffic. Will not start.


Hello Kia Owner,
Regarding the shut down, when was the last time you changed the timing belt?? Did you know that the twin cam 1.5 lirte motor needs a new belt every 50,000 miles or 80,000 kms.
If the belt has failed it may still be in tact but with the cogs ripped off.
Your valves have collided with at least one piston but it is good you were only idling at the time.
The motor may be worth fixing. I just fixed mine myself. I had to lift the engine after removing the axles. I removed the old timing belt and removed and rebuilt the cylinder head(big job). Two exhaust valves were boken right off and lying inside one cylinder.
Most likely your timing belt failed as well.
