My automobile starts running unstable after driving the for long periods that time that does no really overheat just runs top top the warm side roughly 228. As soon as I avoid car and also cools down runs fine. Have checked the fan does which does not seem come come on choose it should or blow as hard as that should and do not think it is the thermostat due to the fact that it does not carry out it all the time. However when the starts running stormy it idles really stormy the rpm's go up and also down and when you push the gas it does not want to go favor it is choking. Ns was said to examine the temperature sensor, but I donot understand where it is located at or where to even uncover it.
