I have a 2004 kia amanti, check engine light was on and i was told to change the o2 sensor and catalyic converter. I changed out the down stream o2 sensor and now the engine is idling high
my car will not go over 20mph, and is getting hot quickly.
i bought the direct fit catalyic converter as told, however
now the mechanic is saying that it may be an electrical
problem yet there was no problem with my car before the
o2 sensor was touched
