2001 dodge dakota sport with 2.5 engine idles high when I start it up, continues idling high, when pushing clutch in to change gears it idles extremely high

Does it do it if you disconnect the idle air control valve ?
You need to know if its a vac leak or if the computer is making the valve open too far.

92 dodge spirit idling too high

I have experienced this myself. try turning off the ac controls because there is a function in the cycle of the ac system that raises the engine idle to run the ac long as its on, the engine idle is raised slightly, and higher when warmed up. also, if you tap the gas momentarily it may "kick down" but takes a few seconds to slow if this doesnt work, try this can remove the negative battery cable with the key in the "run" position,(motor not running), then shut the key off and re-connect the battery.. turn the key on for a few seconds...(this resets the factory presets in the on board computer and the issue may be resolved) also there is a manual reset idle screw located on the back of the t.b.i. unit that controls the basic idle speed. mine is a nut over a slotted stud that gets turned to make the adjustment with a screwdriver and once done locked back by the nut. gotta remove the aircleaner housing to see it behind where the accelerator cables hook up to the tbi unit...good luck hope your not confused by all car has over 300000 miles on it..the original engine and been rebuilt totally at least twice..3 head gaskets, 4 timing belts, and on its second gas tank.pump went bad in the first one, and changing the tank was cheaper than doing the pump alone.right now my issue is that my key part of the ignition fell out of my steering column so I am left starting the car with a screwdriver(what fun!!!) and my speedometer dont work because the sensor went bad and the cruise dont work either as a result. gotta spend a day at the junkyard for parts to fix it..part of the fun of older cars....good luck..jerome

Rpm is high and when i open the ac the car go off when i brake

your rpm is to high adjust your normal idle to .85 when a/c adjust the actuator to reach rpm .95 approximately but be sure not over to 1.

When air conditioner is on, and the car is idling the rpms spike

You most likely have an AC compressor that is cycling on and off to often, this causes the RPMs at idle to fluctuate. The rapid cycling of the AC compressor is caused by a low AC system charge of refrigerant due to a leak in most likely the compressor shaft seal. Please have an AC repair ship confirm this educated guess..

While driving car has trouble shifting into gear , and when parked it idles to high.

Make sure high idle linkage is allowing it to kick down after it warms. otherwise back out idle screw.

When i put it into gear the car dies

Sounds like the kick down cable is not working properly. The kick down cable is the cable that tells the transmission to down shift depending on the throttle position. If the cable fails then when the car is turned off and restarted it is in too high of a gear to go and bogs the engine till it dies. Check this out and see if this doesn't get you back in business. Hope this helps. Good luck. cj2176.

Car won't shift from P to R auto trans in Nissan Pathfinder 2008

With the ac, sounds like you definitely have a short with the ac electrical wires. Have a mechanic check that out. 2. The wiring for the dashboard gauges may have tears or something is causing high resistance in them or you may need a new dashboard itself. Have that checked too.

As far as the brakes when you trying to change gears, what do you mean brake lock wont open? Finally with the RPM, I dont think your dashboard gauge is working correctly so you may need that replaced also.
