i never fill it up all the way.. i close the gas cap till it clicks alot
and yes its ONLY when i fuel up.. never any other time.. rough start after pumping some gas
edit: maybe too low of octane? i use 87 arco.. cause its the cheapest..
No, it's not a low octane problem. Based on the information you;ve given us,
It has to be something to do with
1. pressure in the gas tank.
2. the sensors trigger something and then feeding wrong info to the ECU, then the ECU adjusts itself to correct the correct amount of air/fuel mixture, the next time you start up, it's fine. That is the only thing I can think of. I do know the ECU is smart enough to adjust accordingly to changing fuel octane levels, oxygen levels, etc. My guess is a sensor or ECU problem.
Camry's do have a sensor which detects the gas pressure.
If it were bad gas, octane, etc, you would experience the rough idle everytime you start up, etc, not after you fill up.
Are you running your tank near empty?
Your problem is odd.
Not octane problem because there are millions of Camry's out there using 87 octane and someone would have posted something here by now. I run with 87 octane too. Besides octane problems dont happen just after a fill up, that makes no sense what so ever.
