Question about 2007 Kia Rio 5 Sx M/T Hatchback
Loosing power-replaced catalnic converter recently- replaced coil pack 2 years ago; power brakes went out temp. yesterday started working again 2 miles later; no miss just power lose?
Kia take more than one O2 sensor, and they are probably original equipment, so start there. Also, replace plug wires. There is also a fuel filter that is the old style filter, needs replaced too. This sounds like all it needs to me is some TLC!!! O2 sensors are going to be $130.00 or less. Plug wires are $30.00. Filter-$10.00. Not too bad a price to get your performance and economy back!!

How many miles on the plugs and wires? Misfire can be caused by either plugs or wires, after that check the injector for that cylinder. Let me know what u find. Curt

You need to find out the error codes being generated when the light came on. These codes will stay in memory until being reset by a code reader. The reader plugs into the OBD II port under the dash, near the steering wheel. (OBD stands for On Board Diagnostics). You can buy or rent these readers for not to much money now a days. Costco has a basic one for about $40. http://www.kiatechinfo.com/index.asp This is Kia's tech website. You, or anybody else, can register there and get loads of information about your car, including what the error codes mean, for free. Good luck!

I would suggest that you take it to another shop and have the system checked by a technician.A good pad to install is wagner thermo quiet brake pads and have them check the thickness of the rotors also.A good technician will check your complete braking system to make sure there are no faulty parts.

Testing the coil packs is easily done - if you have the right tool & know how to use it.
You'll need an HEI (High Energy Ignition) tester kit, sold at any auto parts store, for about $30.
Harbor Freight Tools sells a basic kit for $16.
Simply place the tester on the spark plug, and plug the spark plug wire into the back of the tester.
Proceed to do this for each of the cylinders, checking each for (a) presence of spark, and
(b) intensity of spark, which should be equal across all cylinders.
The tester lights up each time a spark plug fires, and you use the tester by watching it as the engine runs.
This test is a good test to utilize for the coil packs once the spark plugs and spark plug wires are known to be good (the tester cannot differentiate between a bad spark plug wire, a bad spark plug, or a bad coil pack).
A really good indicator that a coil pack has gone bad/marginal is when the tester shows
weak spark going to both cylinders firing from the same coil pack (when compared to the
Alternatively, Pep Boys/Advance Auto Parts/AutoZone offer diagnostic services that may include
ignition testing (I know that they do starting/charging system testing). According to www.advanceautoparts.com, they offer free "Electrical Testing" which includes battery, starter and alternator.
Also, Advance Auto Parts/AutoZone have an extensive "Loaner Tool" program, and you may be
able to borrow a HEI ignition tester kit (for a refundable deposit, of course) at your local store.
Another free helpful service at Pep Boys/Advance/AutoZone you may want to try is a free
"Check Engine" light service - a badly missing engine will be detected by the car's computer,
and since you car was manufactured after 1996, its computer port is OBD-II complaint.
Codes you may run into with a missing/misfiring engine:
P0300 - Random/Multiple Cylinder misfire detected
P0301 - Cylinder 1 misfire detected
P0302 - Cylinder 2 misfire detected
P0303 - Cylinder 3 misfire detected
P0304 - Cylinder 4 misfire detected
P0305 - Cylinder 5 misfire detected
P0306 - Cylinder 6 misfire detected
P0307 - Cylinder 7 misfire detected
P0308 - Cylinder 8 misfire detected
