I went to Autozone but, they didn't want to help that day, said the scanner was broke. So, I went to a friends gas station and he scanned it to find out it had a bad "o2" sensor. They put new part in $112 plus $75 labor and reset "check engine" light. So, I guess I'm good for another 6 years??? Still gotta LUV my 99 Accent, great gas milage at 37 miles per/gallon and at todays pump prices, the envy of all co-workers... also "Pimping My Ride" in the audio area, today some 5 1/4 Kenwood 1389IE - 3 way speakers go into the doors to get some great midrange sound, I hope!!
