Engine Mechanical problem
1999 Ford F150 6 cyl Four Wheel Drive Automatic 270000 miles
my engine has a high Idle problem.I've replaced the IAC and thermostat. No difference. This problem occured after I noticed my coolant gauge stopped working. It is not working still.I bought a new one but cannot find where the sensor is located on my 4.2L engine.I've been told it is on the top front of the intake manifold. But I don't see it.I'm stumped fist as to why it idles so high. I'm getting lots of heat in the cab.I've also checked for vaccuum leaks but can't find any.
