Intrepid stalls

I have a 1996 Intrepid witht he 3.5 in it. It runs good on start up and up till it almost reaches operating temperature then it stalls or dies sometimes jerks hard and you feather the gas or punched it to keep it going then runs perfect after its warmed up any ideas what the problem is

uuuuwwww,nice.this a intermittant and hard to find prob.but,you need a tester for injectors and fuel pressure,and means to see spark at the plugs to i.d. what is stopping it.if you can keep it running as you have described above the most likely deal is the t.p.s. sensor[throttle position sensor.]you can check this by simply un-plugging it and it will sub it's own numbers to keep itself running as a test....only! m.a.f.[mass airflow sensor] is sometimes the same issues.check engine light on? scanned code?? help me here!!if it comes to a 02 problem you might have a catalytic converter issue but that would normally cause some backfiring,fuel economy,or unusal driving smells and performance probs.re-post answers.

3.5 does not have a MAF it is a speed density fuel injection system.

oh yeah to almost every mech. maf and a map is almost the same sorry for the oops in labelings jpb53.

still cant figure this out only happens in the winter it seems cold weather?????
