2.5L mis at idle.

975

Asked by Oct 10, 2013 at 01:22 PM about the 1999 Chrysler Sebring 2 Dr JXi Convertible

Question type: Maintenance & Repair

My Sebring Jxi with the 2.5L starts to  flutter or mis only at idle after it has warmed up. Once I leave the light it hiccups a couple times and starts running normally. No codes are being read with the ignition on or with the engine running before or after it's up to temp.
Any ideas ?

OK So far changed plugs, wires, cap, rotor, still not getting any codes and it still is missing after it comes to temp and is at idle.

What mileage is on the car

Throttle position sensor may be malfunctioning also wiggle test wires connected to tps.

Disconnect ecm let sit 30 mins, reconnect and start.

The vehicle has 117,000 miles. Now its buried under a foot of snow so I wont be able to try these last suggestions for a bit. A little more history. In the last couple years also have replaced distributer, egr, crank sensor. Also the sensor on the bottom of the throttle body. I'm thinking that was the idle sensor? Most recently which started all of this past summers drama was i believe a p205 code. I would have to check my notes to verify that number but it was injector 5 code. I changed it and verified wiring and signals. And also resistance on remaining injectors. this cleared the code and the constant rough idle that felt like a misfire that would not go away. After that is when the above started and replacement parts. Strange that its only when its warm and no codes. O2 sensors seem to be acting properly while watching on diagnostic meter. With b1 jumping hi/low and b2 staying steady hi. Ive read intake air sensor has a similar symptom. But havent had a chance to look in my service guide to see if it even has one.

Would i want to disconnect the ecm while its cold and running fine or warm and missing.
