The Kia Optima is a mid-size car produced by Kia Motors beginning in 2000 and marketed globally with various names. Firsts-generation cars (2001-2005) were generally sold as the Optima, though the name Kia Magentis was used in Europe and Canada when sales in those regions began in 2002.
I replaced the throttle positioning censor on my 2004 Kia Optima v6 and now it idles high and shifts at about 4000 rpm's. How do I adjust this and what is the proper rpm?
joe, this may have to be done through a dealer. The ECU may have to "learn" about the new TPS through the KIA software. I would try a reset by unplugging the positive battery cable for something like 10minutes and then reconnect. Hope this helps, good luck.
