Whoever told you to replace the harness wasn't very specific. It's like taking your car to a shop and saying fix it without any details.

First, there are sever wiring harnesses throughout the vehicle. I have pages of schematics, but without knowing where to start, they are no help.

Nest, I really have to question if a wiring harness has anything to do with this. Tell me, does this happen all the time regardless of how much fuel is in the tank? The idea that it doesn't start right up after stalling may be helpful. When it won't start, you need to check if there is spark and fuel getting to the engine. There are directions on our homepage under the Repair and Service section.

Try to check those things when it won't restart and let me know what you find. Also, let me know if the check engine light was staying on.

Thank you for getting back with me so soon the check engine light isnt on at all like I said it was running fine I changed the spark plugs and the oil it seems to be running fine it starts right up when in idle it doesnt stall out also its stalling out when I turn the ac on if that helps at all I thought it was the fuel filyer as well but I cant find it either on that car. Do you know where the filter is located does the intrepid have one some people say it does some say it doesnt if so wheres that at?

Okay, I think I know what is wrong. Since it stalls at an idle with the AC on, that tells me the idle air control valve (IAC) isn't compensating for the added load on the engine. When you turn the steering, there is also an added load which should be compensated for by the IAC. Do me a favor, start the engine and pay attention to the engine speed (RPM;s). Now, turn the steering all the way left and let me know if the engine stalls. Pay attention to the RPM's and see if there is a change.

As far as a fuel filter, it is part of the fuel pump assembly.

When you are driving, the transmission is in gear which also adds a load to the engine. That in combination with the turning, ac. I feel is stalling the engine. I really believe it is one of two things. Either the IAC is bad or there is a vacuum leak on the engine.

Tell them you need the idle air control valve (IAC). It responds to the usage of the AC, but isn't an AC component.

I don't know where you are located, but if there is a place like Auto Zone, they can give you a print out of location and replacement procedure.
