Stalls at idle?

Engine Performance problem
1997 Chrysler Sebring 6 cyl Automatic 165k miles

My 97 Sebring misses, hesitates, sometimes stalls at idle and initial acceleration. No check engine light. My Actron scanner showed pending code of Multiple missfire #1, 5, 6. This car had a tuneup about 30k ago, new fuel filter this spring. So far I have: pulled and checked fuel filter (ok), added fuel treatment and prem. Gas, cleaned dist. Cap contacts & rotor, pulled cat. Converter and "inspected" it, changed IAC valve, cleaned throttle body. After IAC valve installation car started, revved, I drove it at a constant 40mph per installation instr. It threw a CEL code high current to TPS. That cleared, thinking that may be part of the re-learning process. The car idles about 700rpm. If I carefully ease into the throttle it will speed up. If I just push on the gas it wants to stall. I adjusted slack at throttle cable and realized the car will not maintain an rpm between 700 & 1500. It's like all or nothing. I've ordered a new TPS which will be in tomorrow. Also- my diag. Scanner shows no 02 sensor signal (no light or code) I find it hard to believe all 4 o2 sensors would go bad at once, is there a relay or something I can check? It's been 24 hrs. And I haven't received a replly. Do I need to donate more than $10 to get help?

Today I checked EGR valve (ok), cleaned ITC (OK), replaced MAP sensor and TPC sensor. Checked again for vacuum leaks. Still have miss at idle. Car drove good at highway speed. Misses at idle, wants to stall if you give it the gas when engine is at low speed.

I have replaced many parts in my sebring.I just had a water pump seize, which chrsyler put on, so that in turn caused my tensioner pulley and my idler pulley to go. My timing belt, serpentine belt were replaced and I had a major tune up done, and of course another water pump. Double platinum plug are in the car now.

Since that the check engine light is on solid. The car dies at idle until it warms up. After I am driving the car about 10 minutes there is no more dieing at stop signs or any other time. Once it sits over night we start all over again.

Which sensor could be causing this?

Thank you. I will certainly do that.

After engine warms up it dies when you come up to a stop. Will restart right away but idle is rough, also smells like it might be running rich. 2.4L 4 cyl

Car will not idle in park, or in gear. I have replaced the map sensor, and the pcm. Now have no trouble code, but the car still will not idle.?

Did you change out the PCV valve recently. This prevents a pressure overload in the crank housing allowing the pistons and crank to run freely.

Another more serious problem is that your torque converter could be going bad. This causes a lot of resistance to the engine preventing it from idling at its normal steady speed. Sometimes a faulty torque converter will not show up on any diagnostics test considering there is not usually a sensor directly related to the converter. There will also be a severe loss in acceleration and horsepower.

There may also be a simpler less extreme problem where there is not enough air passing through your intake manifold which will also make things harder for the engine to idle. This can be resolve by recalibrating the manifold.
