When in the back of the taxi, Butch takes his boxing gloves off and then throws them out the window. When he throws them out you can hear them hit the ground perfectly as if they weren't in a moving car and just parked.
When Mia finds the bag of heroin in Vincent's coat, she states, "Hello." A second dubbed "hello" can clearly be heard under the first, possibly due to original dialogue not stricken after an ADR take was added.
[2:07:26] When Winston Wolf departs from Monster Joe's in his Acura, he takes a hard corner, but the sound indicates continuous acceleration in a straight line. While the acceleration is possible, it would sound different going around a corner.
Jules purports to quote the Bible several times in the film ("Ezekiel 25:17"). In reality only the final line of this recitation is correct for this Scripture reference, so each time it is a misquote. Tarantino stated that this was intentional to give insight into the character's psychology.
After shooting Vincent, Butch pushes the bloody door open with his fingertips (thus leaving bloody fingerprints). He then proceeds to wipe only one side of Vincent's gun with clean hands, despite never washing them.
[1:48:19] In the apartment miracle scene where Jules and Vincent are about to be shot at by the kid in coming out of the adjoining room, there are bullet holes already clearly visible in the wall behind them.
[00:04:41] when honey bunny pulls out the gun, she yells "Any of you fucking pricks move, and I'll execute every motherfucking last one of you".
When the same scene is repeated at 2:18:00 ,the dialogue slightly changes to "Any of you fucking pricks move, and I'll execute every one of you motherfuckers".
[57:12 - 58:18] When Mia overdoses and is taken to Lance's apartment, a dot is drawn on her chest to show Vincent where he will be stabbing her with the adrenaline shot. After she gets up, the dot is gone.

When Jody comes out of the room Lance has been in looking for the medical manual, she does not have any of her jewelry piercings in her face. A few moments later when they're about to give Mia the adrenaline shot, the jewelry has appeared on her face.
[2:10:01] When Jules and Vincent are in the Hawthorne Grill diner at the end of the movie, the ice in their water glasses changes. At one point, it's completely melted [2:11:38]. Seconds later, ice reappears in the glasses.
[50:23] After getting back from Jack Rabbit Slim's, Mia has Vincent's coat on. When she is about to light herself a cigarette, she isn't wearing it, but when she reaches for the lighter, she is wearing it again.
When Vince and Mia come through the door of Mia's house after going to Jack Rabbit Slims, it is quite clearly daylight, as if they have been out all night. The same when Vince is in the Bathroom, the light from the window suggests it is day. However, for the rest of the scene it is still night.
(at around 15 mins) Vincent's arms when he is talking to Mia on the walkway outside her house after the overdose (eg. Vincent's hands are palm-up and to the side, then the shot behind him shows them both in different positions).
When Butch jumps on Zed's chopper in front of Maynard's store, a two-barreled carburetor can be clearly seen protruding from behind the air cleaner cover on the motorcycle. When Butch pulls up in front of the motel to pick up Fabienne, the two-barreled carburetor is missing.
When Vincent and Mia are talking outside her house, Mia's arms change position between shots. When seen from the front she holds her arms or has them crossed, when seen from behind her arms are beside her body.
[58:00] After Mia regains consciousness from the adrenaline shot, her hand changes position from hovering near the syringe stuck in her chest to being on the floor in the next shot and then rising to hover near the syringe.
[54:16] At the end of Vincent's phone call, (when Lance exclaims "PRANK CALLER" twice), he has a cigarette in his right hand. Facing the window in the next cut, as the car rolls past and Lance throws his hands up, the cigarette is gone.
(at around 2h 07 mins) When they are at Monster Joe's used auto parts, The Wolf is walking to his car, and there are 4 vehicles parked on the left - a truck, a yellow VW bug, a 2nd truck, and another car. But when The Wolf gets in his car and jets off, the 2 vehicles behind the VW are replaced by 2 other vehicles parked further away.
After Jules shoots Brett, he clearly empties his clip as the gun retracts. However, later as the scene continues, after the guy from the back fails to shoot Jules and Vincent, Jule's gun is loaded again as he fires back.
In the "gold Watch" scene, Butch gets out of the cab, then it cuts to Butch paying Esmarelda Villalobos. When the view returns to the whole cab again, you can tell the cab is moved back from when they first arrived.
When Vincent enters Mia's home for the first time, a camera and a camera operator are clearly visible in a reflection on the windows in front of them. They have a black blanket or tarp covering them to make them harder to see.
[1:06:49] As Vega walks through the corridors to find Marcellus talking to Butch's trainer (after the deadly boxing fight), some equipment, and a crew member wearing a baseball hat, is visible through a door on the right.
During the Bonnie Situation scene where the guy comes out of the bathroom and fires and misses his entire load at Vincent and Jules, you can clearly see the two squibs on his chest under his sweatshirt, where he is going to be shot.
[1:26:18] When Butch opens the door of the Apt/Condo with a Brass Kwikset key, he turns the key clockwise, which in fact would actually lock the doorknob. Turning it counter clockwise unlocks a Kwikset entry lockset.
In the beginning diner scene when Yolanda and Ringo are about to rob the place, Yolanda yells "...and I'll execute every motherfucking last one of you". At the ending diner scene (which should be the exact same), she yells "...and I'll execute every one of you motherfuckers". This is to show different perceptions of the same event. The first being Yolanda's and Ringo's and the last being Jules'
At one point, Vincent says, "I don't watch TV." Later, he mentions something he once saw on the television show Cops. The phrase "I don't watch TV" generally means that the speaker does not make a habit of watching television. It generally does not mean that the speaker avoids television completely and has never seen a single episode of any show ever. Most people who "don't watch TV" will watch TV from time to time, depending on the situation at hand. Vincent seems to be no exception.
[1:09:18] In the taxi, Butch throws his boxing clothes out a fully-open window, and Esmarelda tosses a butt out her open window. The squealing tires, near-miss as she leaves the alley, and background indicate she's driving fast. But as Butch smokes the cigarette, its smoke drifts slowly through the car, indicating it isn't moving because no wind is coming through the open windows. However, the back projection is heavily stylized in black & white, so the director clearly did not intend this to be a realistic shot. Although the shot may have been intentionally unrealistic, when Butch throws his gloves out the window a "plop" can be clearly heard, indicating no vehicle movement.
Whenever the two shots from inside the apartment are shown, they are shown in different perspectives, so it might be that all goofs spotted in the two apartment scenes can be considered as being different characters in the movie perceiving things differently.
When Vincent Vega drives up to the house with Mia ODing and crashes, you can see tire tracks in the grass where the original car continued through out of shot so when the camera tracks around it shows only the placed car.
[1:48:19] In "The Bonnie Situation" when the man fires the revolver, the bullet holes show up before they are fired, and it's clear that some of the bullet holes have been made from the other side of the wall at angle.
(Deleted scene) When Mia interviews Vincent on the video camera, the perspective of the video camera (and Mia) keep moving, but the cutaways to Mia holding the camera are the same, being stationary with the same background.
The goof items below may give away important plot points.
[1:33:03] Errors when Marsellus and Butch are trapped inside Maynard's basement: 1) When he starts sprinkling water to wake them up, Butch is seen bent further down in the back shot. 2) Maynard then sprays them upwards, but in the next shot the water is coming downwards. 3) When Maynard finishes sprinkling, Butch turns to Marsellus, but in the next shot he is facing away. 4) When Maynard goes upstairs to open the door for Zed, Marsellus's shirt is untucked covering his crotch and Butch's blood stain on his shirt looks darker. In the next shot, Marsellus's shirt has changed as well as the blood stain on Butch's shirt, which looks lighter. After Zed walks in, the shirt and the stain change back.
[1:44:42] When Butch walks out of the shop and stands in front of Zed's chopper he is holding the keys in his left hand. However, when a close-up is shown of the key's they are clearly in his right hand.
[1:26:40] In the "gold watch" scene, when Butch grabs his watch he turns left out of his room into the kitchen. When he shoots Vega you can see that his room is on the right hand side, you can see the kangaroo where his watch was, but after he looks at Vega's body he takes a left into his room which is now the living room where he exits the apartment.
[1:51:10] In the scene where Vincent shoots Marvin, the bullet goes through his head causing blood to cover the rear window. From that range, the bullet would have gone through the window as well, which it did not.
