okay well the other day when driving i noticed that the car started to bog down a little and would be driving and i could feel and hear the car losing power then gaining power, wasnt throwin any CEL's kept driving and a CEL came on and the problem goes away and the car drives fine now when i checked the code i got 43 and it is related to the fuel supply system, so i took the fuel filter off and filled it with seafoam to try and clean it out and also clean the injectors, ran better for a while now it came back, im thinking it is my fuel filter because it is intermittent and the is pretty old, maybe 15k on it so i think that will be my first place to start. im just hopin that it isnt my fuel filter, or possibly an injector going bad. but just wanted to see what you guys think and use some of your help also. thanks alot.

 

Could also be a failing fuel pump or pgmfi (not sure if your teg has this or not).
