I would highly recommend that you go to the local parts store and purchase a Haynes Manual for your vehicle, they are around $ 25.00 Canadian. As when you do your head gasket you wil need to remove your timing belt and this is a procedure in it's self. then you will neen certain torque settings. This manual will provide you with all of this information step by step. they are designed for the do it yourselfer. They also cover many other issues that you may come across through out the ownership of your vehicle. I know that the last ting you need is an added exspence but these manuals are well worth the small investment. There is a site that you can find hrough google search that you can find factory service repair manuals for your vehicle, however they only have a layout for a 4 cylinder engine in there drawings and this is alot different then the 6 cylinder. As the procedure for repairs is totally different. I hope that this helps and that you take the time to rate any solutions you receive. Good Luck.

The toyota previa uses a formed silicone gasket for the valve cover and the cover is held in place by metric shoulder bolts ( 10mm). The valve gasket leaks because you can't get enough preload on the bolts to re-seat the old gasket when it gets old and shrinks. The shoulder bolts only allow you to tighten the gasket enough to seat the shoulder on the bolt. If you continue to torque down the suspected bolts, you will snap the bolt off ( don't ask me how I know this ). You can either 1.)replace the old gasket with a new one or 2.) remove the existing bolts around the leak area and put in new metric bolts that do not have a shoulder. You may want to put in a small sleeve into the existing bolt hole but shorter than the thickness of the valve cover to account for the smaller diameter bolt. You can now torque down the bolt and get enough preload to seal the valve cover without removing the old gasket. Make sure you use a torque wrench ( in-lbs) or be very careful not to snap these small valve cover bolts.

SOURCE: 1993 toyota 4x4 idle problem
sounds like your throttle positioning sensor is not set right so i would undo the two phillips heads that hold it and turn it till the idle doesnt fluctuate should be turned most of the way to the front of the truck. Also check your idle screw that throttle body could be set different.
