1998 Chrysler Sebring LXi Coupe Stalls at Stops: 7 Likely Culprits

A 1998 Sebring LXi (2.5L V6 typical) that stalls at idle (red lights, stop signs) usually suffers from one of these seven issues, ranked by probability:

1. Idle Air Control (IAC) Valve — #1 Suspect

• Symptom: Stalls when warm, AC on, or after throttle release
• Fix: Clean (throttle body cleaner) or replace ($50–$120). Common on Chrysler 2.5L.

2. Vacuum Leaks

• Check: All vacuum hoses, intake manifold gasket, PCV valve, brake booster line
• Test: Carb cleaner spray — RPM change = leak found

3. Dirty Throttle Body

• Carbon buildup blocks idle airflow. Clean thoroughly (remove, soak, brush). Relearn idle (disconnect battery 10 min).

4. Fuel Injector Issues

• Leaking/clogged injectors → rich/lean at idle. Injector balance test (scan tool). Clean or replace.

5. Weak Fuel Pump / Pressure

• Spec: ~48–55 psi (key on). Test at fuel rail. Failing pump = stalls under load/heat.

6. Ignition: Plugs, Wires, Coil Pack

• Worn plugs (gap >0.050"), cracked wires, failing coil → misfire at idle. Replace per schedule (plugs 30K, wires 60K).

7. Clogged Fuel Filter

• Restricts flow at low RPM. Replace if >30K miles. Located on frame rail near tank.

Diagnostic Order

1. Scan for codes (even if no CEL — pending codes exist)
2. Check fuel pressure
3. Clean IAC + throttle body (cheap, high yield)
4. Smoke test for vacuum leaks
5. Injector balance / ignition scope

Pro Tip

If it restarts immediately and runs fine until next stop → IAC or vacuum leak 80% probability. Start there.
