was sitting at idle today just buring some gas, and all of a sudden my cel pops up. I switch ignition off and check for cel it red 43. fuel supply system... When I started up again it didn't come back..

Did you notice any symptoms? Car misfiring or anything like that? It could be a number of things. When is the last time you changed your fuel filter?

that code is a bitch. it means car is running rich.

some possible solutions I have read about are fuel filter, fuel pump (anything in the fuel delivery system), running injector cleaner,etc. check all your connections as well. any symptoms lately?

I have also heard a O2 sensor can cause that code too

O2, pump, regulator.

It try to test the regulator first.

haven't had any more cel. I pulled the "back up" fuse to reset the ecu. Its ok so far. I was thinking gas filter cause I never changed it and I don't know when its been done...

I havent experienced this code anymore after I pulled my plugs and dizzy cap/rotor to inspect and clean the contacts. I also ran some fuel system cleaner and checked all my engine bay electrical connections including the fuel injectors and so far knock on wood no code 43 and I have my power and throttle response back im happy! I really think it was the fuel cleaner and then possibly dirty dizzy connections.
