If things couldn't get any more weird, now i am having a problem with my teg hesitating when i put the gas to the floor shortly after starting the car up. this only happens when the car has just been started and warmed up. Atfer the car warms up, there is vitually no problem. My guess is the fuel filter, but should i be looking for anything else? all my 02's are fine, i really hope it's just the fuel filter. Any suggestions?
