Default 2004 Kia Rio, Starts, Idles, but no power with acceleration

Greetings, and thank you in advance.

Vehicle: 2004 Kia Rio 1.6 FI

Symptoms: While driving, after covering about 125 miles on the highway, having turned off to a secondary road the vehicle lost power. It would idle fine, however when pressing the accelerator, there was no power, it would max out at about 20 mph (floored). It sputters a little when pressing the accelerator and occasionally dies. Stopped the car, self towed to a safe place. The "check engine light" is on, however this light has come on intermittently for months (according to the service department a faulty trip mechanism). It did go in for diagnostics (free, under the table kind) and was suggested that it was a fuel or exhaust problem. They either did not get codes back or were not in a sharing mood.

Weather: It does happen to be winter, with snow on the ground and the car has been out in the cold (though "winterized")

Fixes: 1) Started the road trip with a full tank of fresh gas (with a little STP additive as it was cold out), as such I don't think it would be a fuel issue. (2) Replaced the fuel pump / filter (they are one unit, in the fuel tank, no other filters located in-line). (3) cleared the fuel line with air compressor (the line was not attached at either end during this) (4) Tested the replacement parts / fuel delivery, which appears adequate / steady up to the rail.

Questions: What would be the next most likely and least expensive cause? (the car really isn't worth that much other than being a needed mode of transport right now).

My ideas: (1) Wires / plugs. (2) Distributor (though I am not sure it has one as i can only find listings for the ignition coil). (3) computer or sensors (I am not sure which sensors though ?). (4) vacuum system / hoses? (5) Even though it is getting fuel up to the rail, a clog or problem at the injectors them selves?

Any suggestions / advise greatly appreciated. Preferably in a least to more expensive outlook, tempered by the most probable cause.

Thank you.

Try goin to kiatechinfo web site. Its free, you have to register. It showes a fuel filter at the front drivers "USA drivers" side/corner. Auto zone also lists this item also.

Other than that, take the car to Auto Zone/Advance Auto/ or other auto parts store and have the codes read, its usually free, they hope to sell you some parts.

Did you just change plugs?

Could be moisture on the plug wires, these Rio's seem to have this as a problem. Could be a bad 02 sensor. Lots of miles? Plugged cat. Other sensors. Need codes.



You don't state how many miles the car has, or where you're at. I'm assuming in North America, could make a difference. Don't really like to assume, we all know what that does to both you & me.

There where some 2004 rios that came WITHOUT fuel filters on the line, the are with the fuel pump. It was a stuiped setup kia did. As your problem with not going over 20mph maybe a vss (Vehicle Speed Sensor) and the rio's only come with coils. Distributor caps only come on older cars. They stopped doing that in roughly 2000

Sounds like crankshaft or camshaft sensor is faulty. You should try diagnostic.

Broken gearbox makes me mad...

You really need to scan for codes it could be many things. First of all does it rev normally in neutral / park? If so then it could be the Vehicle Speed Sensor or Turbine Speed Sensor on the Automatic Transaxle. If it does not rev fine in neutral / park then it could be a faulty Cam Position Sensor or Crank Position Sensor, it could be a faulty Throttle Position Sensor or even a bad Mass Airflow Sensor it could be as simple as a bad fuel filter or a bad spark plug or wire.

I had the same problem, it was the wiring harness going to the MAF sensor. I would check each one.
