Symptoms 2000 kia sportage does not do all the time. Starts runs well but driving road 50mph almost as if ignition shut off split 2nd. Stop car and while running in drive seems to run smooth then into park start missing. Also gauges speed temp gauge bounce at one point with car in drive turned air conditioner off car shut off. again does not happen all the time. when idleing at times shifting between drive and park will make it stumble. seems to to it only shifting from drive to park.
Some makers used Vacuum releases for their emergency brakes which had a Vacuum switch connected to the shift assembly. This would account for a stumble if Vacuum vented out through this switch.
More common for shifting stumble to occur from Park to Drive, engaging a load on the engine, not to stumble to a freewheeling Park position. Sounds like idle speed control is sluggish to stabilize the motor.
You also have idle speed control problem with A/C, kind of shows that A/C was what kept the engine running because when you turned the A/C off, the car died.
I am going to give you some Websites for wiring diagrams. Alldatadiy.com amd Autozone.com with free wiring info upon registering your vehicle.
It seems that the base Idle speed control is not working and the A/C idle speed control is.
Also check for Vacuum leaks on the intake manifold by spraying water from a pumpbottle on the seams of the gaskets.
Check ignition Relay or ignition switch for random cutouts. The fusebox layout is on the Autozone site.
I hope my solution helps.

Yes there is a sensor that controls Fuel/air ratio.It's called a MAF (mass air flow sensor)
But I think you should have the EGR (Exhaust gas recirculation)valve checked
and The TPS (throttle position sensor)maybe dirty.
Although may things can cause this issue,I would look at the items above first.
Please rate this a blue fixya
SOURCE: 2002 kia sportage temp gauge runs hot while driving
Cheak to see that the coolant fan is operating with the A/C turned on. The fan has to work to help the engine stay cool and help the A/C. When you apply heat on the control it acts to reduce the coolant temp. You will have to get the coolant fan operation checked. This can be :fan motor, fan relay, temp sensor and computer. Good luck

i have a kia make sure you have alot of coolant and depending on the age you may want to change the thermostate. do you have the check engine light coming on.
