Please help! I've got a "check engine" and "VSC Off" lights on. It happened after I fuel my car and overfill it with a gas. So car idling uneven. Diagnostic from AutoZone says P0174 and P0171 and it says If bank one and bank two set together suspect a fuel condition or MAF sensor fault. Also it says it could be -Failed H02S21 (what is is?); -Ignition missfire; -Fuel injection problem; -Oxygen sensor defective; Please help to figure out where to look first! I only have a problem when gas tank overfiled. Maybe I need to check gas pump firs to check filter and so on?

Thanks for reply BUT it was all off topic! Do you have any thoughts about my car case? It is still abnormal, and finally today I've got the Check engine light on after fueling, and when it idling it is working not right. PLEASE help

Hi everyone, I have a strange situation with my car. I purchased it week ago, and everything fine. The car is 2003 GS300. Today I got it to gas station first time, the tank was almost empty the indicator of low fuel was on. I put 17 gall, so tank was full till the top. I close the cap till 3-4 clicks, started the engine and began moving, suddenly it started to lose RPM and stalled. I start it again and when I moved it was jumping because the RPM was jumping. When I got to my driveway I put it on a parking and started watching on a RPM gauge pressing and releasing gas pedal. So when it was idling after one minute it stalled again. I turned it off and open fuel tank cap and closed it back, started the engine and problem gone. I tested it, run couple of blocks around, everything looks fine. So now I am in big confuse what was wrong and will it happen again? Every help very appreciated. Thanks.

Hey Vova, privet. I have GS300 2003 and it does same thing. I think this is normal.
