Shortly after purchasing the vehicle used with 16000 miles, I began to notice a vibration and rattling sound while at idle. It appears to happen more often when the a/c compressor is running, causing the idle rpm's to be even lower. At this low idle speed of around 500-600 rpm, the vibration and rattling occurs and only stops if the rpm's are increased. And while driving recently with 32600 miles on the vehicle, the rpm's seemed to be abnormally high, resulting in increased braking effort to slow the vehicle, and at startup of the engine, initial idle speeds of up to 2500 rpm. Engine temperture was also noted to be above the typical operating temperature and could only be lowered by setting the heater & fan on high to remove heat from the coolant. Nlm.
Purchsed vehicle new. After 6000 miles engine developed a rattling sound when cold. Dealer replaced engine and new engine makes same sound after 6000 miles. Dealer says it is a characteristic of the ohv engine. If so, why did they replace it in the first place.
