3.8 Shuddering low idle
 

Hey, guys I ahve a diagnostics question. My roommate has a 96 thunderbird with the 3.8 and while sitting it will shudder and idle down sometimes to the point of shutting off. The only thing i can think of is the coil pack starting to go? it doesnt have a problem with getting gas when you hit the trhottle so I assume theres no problems in the fuel system. Any help would be apreciated...shes getting an earful from all kinds of people taht dont know much and i dont want her spending any money she doesnt have too as we are all a liittle strapped and she recently got raped by firestone for front end work.

Thanks guys!:)

Check the TPS and the IAC. Need to check for codes.
