ICP Sensor Lfe Expectancy
So my 97 ford is experiencing issues with starting hard. I had similar issues about a little over a year ago and was directed to check the ICP sensor. After checking the connection sure enough there was oil inside the plug. I replaced sensor with a genuine ford part and a year later I started experiencing hard starts again. I just checked the year old ICP sensor and found oil in the plug again. Is this normal for an ICP sensor to go bad so soon or could there be some other cause of my issues?
