I'm a little late to this thread but have you pulled
the codes and seen if any errors are reported or the

If idle is not changing with removing the dipstick
there is a vacuum leak somewhere.
Fix your radiator/cooling before moving on. Its
difficult to diagnose these problems if you can only
run the motor a few minutes.
