Motor stumbles a bit after filling up...
Do any of you guys get a steady stumble at a red light after you fill your tank? But the next morning the car is fine and throughout the rest of the tank?
Thanks !
Thanks !

My car has done this occassionally when just started cold with a recent full tank. Not sure why wanted to replace my fuel filter to find out there isn't one to replace unless you want take the fp out.

I have had similar issues on my evo with the motor stumbling. It was pretty random, and would not do it for days at a time. Once in a while the car would also stall while in idle.
My problem was solved by replacing the IAC on the trottlebody.

I have this issue after every fill-up. It only last for the first few minutes of driving and only at a stop like you have stated. Not sure if I need to drain the tank and try to get out some possible dirt/contamination, or if there is another solution.

^^^I just wonder if filling up the tank may cause small debris to become suspended in the tank...causing the stumbling. The car idles perfectly any other time, and like the OP said, after running the car for a little while. It's only during the first few minutes after fill-up.

One way to check your IAC is to remove it from the throttle body. You can do it without removing the whole assembly. It has 3 screws, but I would use a socket as a screw driver may result in stripped screws.
Once it is removed, plug it into the harness. You will need someone to turn the key to the on position without starting the car. This will send current to the IAC, and if the value does not move out it is time to replace. This device is what the ECU uses to modulate idle.
The only other way to modify the idle is to change the map with flashing software, or adjust the idle screw on the throttlebody. Good luck sorting out this issue.
