Desaccelerates SolvedSolved

Volkswagen Jetta 2003  200000 miles
Hi... when driving my car on the street, the engine suddenly desaccelerates and revolutions go up to 4.0 and the engine feels absolutely strained. When I then press the accelerator, it won't go over 50 mph. It's been a week since this problem appeared for the first time, what can it be?

Many things might be causing your problem: a lack of tuning, uncalibrated TPS or some damaged sensor. You should check the spark plugs and their wiring, as well as the engine itself, which might be needing a service.

It was a throttle issue because when you put it down to drive it slips down the S without knowing. Sucks.

Won’t accelerate

Volkswagen Jetta 2012 Sedan, 2.5L SE 260000 miles
The car starts but idles rough. After driving it a few feet the accelerator will stop working. Shows engine codes for a cylinder 2 misfire and a MAF issue. Have tried changing spark plugs, coils, sensors and gaskets and nothing seems to resolve the issue.

Oil leak from the gearbox

Volkswagen Jetta 2015 Sedan 1.8 tsi 116000 miles
The car doesn't have a launch control feature; I tried pressing the brake and accelerator simultaneously a few times, and afterwards, it started leaking oil from the area where the transmission connects to the engine—though it doesn't leak when the car is turned off.

EPC light, PO2222

Volkswagen Jetta 2012  148777 miles
EPC cans on car shuts off after about 20 minutes of driving it. I haven’t driven the car in about two years now trying to pretty much sell it for scraps because I don’t know what to do with it can’t afford to get it worked on. Had somebody do a diagnostic with a Mitchell one program they came to the conclusion that was the alternator. I replaced the battery about six months ago in the car. Will turn over now, but still has a few lights on the dash in my throttlebody position center and pedal codes are popping up on my diagnostic code reader

Won't move when gas pedal is pressed but engine revs

Volkswagen Jetta 2005 2.5L new sedan automatic 6 speed 130000 miles
Car will not move but revs when in drive or in tiptronic shifting. The speedometer shows the gear display and what gear you are in right, but now each gear is highlighted in a solid red square. Was always just the letter or number. At first I would shut it off and let it sit a minute and restart it and it's good but now it's just stuck like that
