I recently bought this SUV and took it to my mechanic and they found a couple different things, the first was a misfire on cylinder three which threw off a engine light. They changed the spark plug wires and that help but they said that it still has a small misfire at idle speed. They recommended I have some sort of engine detergent added and see if that works, but it was going to cost too much, $800.00. Second they said that the car needed antifreeze and the computer recommended a thermostat. Now I have the truck back and the check engine light is still on but it goes off, second I have run the truck for thirty minutes at idle and the temperature is 209 and check with temperature gun and it shows 187 at the top of the manifold where the coolant goes into the engine. The fans seem to run pretty much all the time once operating temperature is reached, is that normal? And it idles at seven to eight hundred rpm's which makes it feel like it wants to take off. Is that the right rpm's for that engine?
have the same problem?
