I have a 2004 Kia Optima runs fine for a while. It acts as if it is
running
hot; however, the gauge temperature is reading normal. It does not
indicate
that the engine is hot. It will run fine on the highway, but as soon as
I
am in the city it appears that it is losing pressure. Therefore, I have
to
pull over and wait for the car to cool off.
I have replaced the hoses and thermostat. However, I am getting the same
results. The car will barely move and the rpm is off the chart. Until I
let
it cool, off.
I was told it might be a fuel filter. Does anyone have a suggestion what
could be wrong
