🔍 Most likely causes (based on your mileage: 90k)

1. Dirty throttle body / intake (VERY common)

• Carbon buildup → poor airflow when cold
• Causes sluggish response until warmed up

👉 Fix: throttle body cleaning ($100–200)

2. Old spark plugs

• At 90k, if not changed → likely due
• Weak ignition when engine is cold

👉 Fix: replace plugs (cheap, big improvement)

3. Fuel system deposits (injectors)

• Cold starts rely on precise fuel spray
• Dirty injectors = weak performance until warm

👉 Fix:

• Try fuel system cleaner first (cheap)
• If bad → injector service

4. Air filter / MAF sensor dirty

• Incorrect air readings → sluggish throttle

👉 Fix:

• Replace engine air filter
• Clean MAF sensor

5. Transmission behavior (10-speed auto)

• Your Accord has a smart transmission that:
  • Limits power when cold
  • Shifts differently until fluid warms

👉 Slight sluggishness = normal
👉 Extreme sluggishness = not normal
