I have a code P2187 and when I fill my car up with gas I have trouble starting it up

Question

my engine light on I took it to auto zone the code read P2187 What could be the problem and after each fill up my car hesitate on starting

Answer 1

P2187 System too lean at idle

The majority of this code condition is air leakage or vacuum leaks , The MAF (mass air flow) calculates the the amount of air entering into the engine, when there is a vacuum leak or air leakage that gets past the MAF this is unmetered, which sets a lean condition. If the vehicle stumbles after filling the fuel tank and you recieve P2187 this is the purge causing the problem , Recheck the code  if there is a P0456 and P2188 you would need a ECM software update.
