About 8 weeks ago my car was running great. Then one day sitting at a traffic signal it began to run rough - then it ran smoth for a couple of days. Then it started running rough again and the check enging light came on. So I read the codes, and put in a new o2 sensor. Problem did not go away - but the codes changed - injector failure. Gas millage has dropped from 24 mpg to 15 mpg. From the exhaust it is running rich. I tried a working AMM with no difference. I read the voltage for the coolant sensor, it was 3.2+/- at about 75 degrees - a little high. Could this be the problem? If not where do I go from here?
