hi group, i've had no problemas w /my '91 i6 yj in a long time but there is one thing that has bothered me ever since i noticed this happen
whenever the jeep is started the engine's rpm starts out at some 1800 and then works its way down to about 750 rpm where it belongs. but there are two problemas:
- for one, it takes a good minute for the rpms to even *begin* lowering and some three mins before the rpms cross the 1000 rpm mark on their way down. ISN'T THIS A BIT TOO LONG?
- two, this same seemingly prolonged warm-up cycle occurs !every! time i start the jeep; be it on a wintery morning, staring from dead cold or restarting the engine after a five min rest stop, having just driven 100 miles straight WOULD THIS BE NORMAL BEHAVIOR OF JEEP ENGINES? i also have a regular car, a caddy, circa '92, and its engine warm-up time is nowhere near that of the jeep's and there is no warm-up at all restaring a hot engine. why would my jeep be so different?
there are absolutely no other problemas w/ the jeep engine that i know, no codes, normal mpg, etc i made these observations while being parked, just timing how long it takes to get the rpm down under diffrent conditions.
could some1 provide some input, pls? thanx, pete
