First time post... This is a terrific forum and has helped many times. Need help or suggestions; desperate; wife's car. We've had the 99 RX300 for 3 years. Great car. Just started having issues and codes pop up. Replaced a couple O2 sensors. Then MAF code along with others. Before we could do anything, it's now showing 11 codes. Starts, idles fine. In park, engine revs up fine - no missing. When placed in drive, the car begins to bog down, misfire when accelerating. Check engine starts to flash. Replaced MAF - no change. Could not locate any vacuum leaks. Friend said the throttle position sensor... Any suggestions on how or where to proceed?
