Continuity mistake: Just before Peter enters the tunnel in his new car, the white line in the middle of the road is blotchy and not continuous. When the shot changes to Peter's POV, the line has completely disappeared. The next shot which shows the car side on, there is now a straight white line on the road. (00:14:20)

Continuity mistake: After Peter has been to the newly opened bar, he runs to his house door (which is red) and when he opens it, the colour has changed to brown.
Peter Griffin: Husband, Father...Brother? - S3-E14
Continuity mistake: When Stewie jumps on the picnic table and begins his dance, at one point he undoes his coveralls and removes his shirt. In the next shot he is fully clothed.
Continuity mistake: When meg is at the car with the girl and the two boys, the guy on the right has the Q and a basketball above it. In the next shot the basketball becomes white. (00:12:17)
Continuity mistake: At the football game, the row of people behind the Griffins disappear in one shot, and reappear in the next, with not enough time for them to have all moved away, and all moved back. (00:07:10)
Mr. Griffin Goes to Washington - S3-E3
Continuity mistake: When Mr. Weed is crying about losing his job, we see a view of a long line of trees in the window behind him. The camera switches to a close-up of Peter. When it zooms out again, the trees on the right of Mr. Weed are missing.
Suggested correction: I watched this part of the episode twice and no trees are missing in the window behind Mr. Weed after the close-up on Peter. Actually, Mr. Weed's head is covering part of the window where you can't see the trees on the right when he's lying on the table, but when he gets up you can see all the trees.
One If By Clam, Two If By Sea - S3-E4
Other mistake: After the hurricane passes, Peter acts like he's been impaled by a wooden plank. He pulls it out as if it was attached to his right side. However, the way the metal on the clasp was bent, the only way the wooden plank could've been positioned that way is if the metal was over his shoulder.
The Thin White Line (1) - S3-E1
Continuity mistake: When Brian is saying that his family has it all wrong about his drugs, Lois is holding Stewie. In the very next shot of his family from the front, Stewie is standing on the ground, without any time for him to climb down. (00:15:10)
Audio problem: When the English mother at the airport says "These are all ours", she says it in a posh American accent, not an English one. (00:05:30)
Factual error: When Carol gives birth there is no umbilical cord. (00:06:30)

To Live and Die in Dixie - S3-E12
Other mistake: When Stewie is with his 'band' for the first time when he is tuning his guitar, the string he's tuning doesn't match the peg he's turning.
Continuity mistake: When the flag team first walks out to the field, they are all in a straight line. Next time they are in two seperate lines with Meg at the head. Also, the girl with the head brace moves to the front when she is seen in the back. There is not enough time for them to move into the lines. (00:06:50)
Continuity mistake: When Lois is talking to her father about Peter wanting to be friends with him, the two emblems on Carter's shirt disappear between shots. (00:07:55)
Family Guy Viewer Mail #1 - S3-E21
Continuity mistake: Just before the genie comes out of the bottle, Peter's hands move from holding the bottle and the opener away from each other, to opening the bottle with the opener, between shots.
Death Lives - S3-E6
Continuity mistake: In the scene where Peter gets a ride from Cleveland, there is no one behind the wheel of the car while Peter is walking up to the front door.
The Kiss Seen Around the World - S3-E8
Continuity mistake: Brian is looking at board games. Before he spots his favourite (in the wide shot), there is a game of Snakes & Ladders to the left of Chinese Checkers. In the close-up, S&L is gone, and CC has moved up closer to Brian. (00:00:50)
One If By Clam, Two If By Sea - S3-E4
Other mistake: When the cops burst into the house we see the action on a TV as shown by the Quahog News logo in bottom left. However on the TV in the living room the logo is missing. It should be there as well. (00:12:45)
Continuity mistake: As Stewie is about to eat his brisket (just before he throws it at Meg) he is cutting part of it off. Just as he cuts through the shot cuts and you can see the brisket is now back in one whole piece. You can also see the mashed potatoes change from white to green.
Continuity mistake: In the scene where the family are singing an African song, they all point their arms up to the ceiling yet in the next shot, Lois's arms are immediately cupped and pointed downwards - you don't see her moving her arms to that position.
