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.
have the same problem?
