Hey there!
That 2007 Compass throwing you a curveball after filling up, huh? It's a head-scratcher for sure, especially since you've replaced a bunch of common culprits - props on tackling the EVAP, and coils, and cleaning the injectors yourself! Here's the thing: when a car acts funky only after filling up, it usually points to an issue with the emissions system. Since you've replaced the EVAP already, let's look a little deeper:
1.) Rollover Valve: This little guy prevents overfilling the gas tank. Sometimes they get sticky and can cause the engine to sputter or stall after refueling. You might not get a check engine light for this.
2.) Sensor Shenanigans: A faulty fuel tank pressure sensor or purge valve sensor can send wonky signals to the engine computer after a fill-up, causing stalling. Testing these might be best left to a mechanic with the proper tools.
3.) Fuel Tank Overfill: Sometimes overfilling the fuel tank can cause issues. Avoid topping off after the pump clicks off.
4.) Evap System Issues: Even though you replaced the EVAP components, check the vent valve and purge valve again. These control how fuel vapors are released and could cause the engine to struggle right after fueling if not functioning correctly.
5.) Fuel Pressure: When you fill up, it can stir up debris in the tank. Consider checking the fuel pressure at the rail to ensure it's consistent and adequate.
6.) Vapor Lock: This can occur if the fuel system gets too hot and causes the fuel to vaporize in the lines. It’s less common, but worth considering if the car starts fine otherwise.
7.) Throttle Body: Ensure the throttle body is clean and functioning properly. A dirty or faulty throttle body can cause the engine to stumble or stall, especially after a fuel fill-up when the engine might be adjusting for fresh fuel.
8.) Idle Air Control Valve (IAC): The IAC controls the engine’s idle speed by regulating the amount of air entering the engine. If it's dirty or malfunctioning, it might struggle right after refueling.
Listen, you've done a ton of work yourself, which is awesome. But based on this symptom, it might be time to bring it to a mechanic with diagnostic tools. They can delve into those sensors and pinpoint the exact culprit in the emissions system causing the post-gas station hiccups.
In the meantime, try not to top off the tank when you fill up. Leave some breathing room for the system - that might help prevent the stalling.
