when i drive in 1st gear my car starts to bog an jerk really bad but as i get to the higher gears it gose away or doesn't happen as frequent. i changed my plugs i used those fuel line cleaners that u pour in your gas tank. would i have to change my fuel filter? its a 02 lancer OZ rally

You can buy MAF cleaner at any auto store.

If it does have to do with spark it could be a bad plug wire too.
