Re: Code 43 and 32 (Stevebra)
That code 43 is probably just a knock sensor. Could also be a wiring issue. If the car has high(er) mileage, there could be silt, dirt or whatever in and around the head of the sensor and connector. Squeeze the connector and pull it off and give everything a good cleaning. If all else fails, the knock sensors are easy to replace and if I remember correctly go for ~$30.00 each. Change the coolant while you're at it! This is the best time to do it as you'll get much more out of the block with less hassle while the knock sensors are out.
