hi the problem i have with both me mx3s is that when the get up to opreating temp the idle starts to goo up and down on its own. It happen to my first one last summer and it made me park it for the remainder of it and i bought a new one just over amonth ago. and now this one is doing the same thing, on my first one i replace the tps and map sensor. has anyone had this problem as well if so could you help me out.

thanks

Check the accordion hose going to the throttle body for cracks. This sounds like you have a vacuum leak. Check all your vac hoses and finally you may need to check your intake gaskets integrity by spraying carb cleaner/quick start or some thing similar around the base of your intake.
