My car started jerking since last month but the jerking and stalling was minimal, I visited a mechanic and he adviced that I should change my plugs. I bought plugs and fuel filter but he replaced only the plugs and told me that my fuel filter is fine.
I left and the problem still continue and increasing day by day,it can stall when am overtaking which is dangerous.
I then bought a scanner and scanned it and it pulled this code p0457 (emission issue). I went to my mechanic but he couldn't understand where the fault is.I went thru Google and everything is pointing to canister valve bt other mechanics I visited told me that the valve is not the cause. I just left and don't want them to do their usual try try way.
pls does anyone know the solution about the code and if it is smtin I can do by myself bcus the car is now consuming too much fuel and i smtimes perceive fuel odor why driving.
The car is VW Golf Mk3 Auto.

Gazzuzz kindly report here

Your Scan result was nit really given you reason why your Car jerks and Stalls and stalling you mean going off while engine is running. The fault code is actually pointing to Evap Emmision problem. What I will advise you do is do a fuel pump pressure test, have your Throttle body serviced, the pump might nit have enough pressure to push fuel to the to the injectors there by causing the issues you are experiencing and as a result the throttle body ( aka Injector Mouth might have clogged up due to unburnt fuel in the cylinder. In all A Tune up will be a good option.

Emission issue should not cause your vehicle to stall. another thing I'm worried about is the capability of the scanner you used in scanning your vehicle.

Assuming you have used a good scanner, and did not get a code relating to one engine sensor or the other or any other electrical component, then I would suspect the problem is coming from your fuel pump mounting.

Does the car stall even when your tank is half filled? Ask your mechanic to check if your fuel pump is properly mounted in the tank.

Did you service your injectors recently? Smelling petrol while driving may be pointing to leaking injectors or some leak in the fuel lines. This will also explain the stalling with increased engine load

Similar problem, but i think i will go with d first reponder's suggestion.
Started noticing the problems in mine(hyundai accent) after a fuel pump change.

unfortunately am not in Lagos bt I wl ask my mechanic to check the fuel pump and the injector though mine use electric carburetor.It stalls even on full tank and smtimes when I remove my leg from the pedal it wl drag as if I applied the brake and smtimes it wl be moving at the same speed as if my leg is still on d pedal.

No,I didn't, am also trying to figure out if the throttle could also be another culprit.
Fuel pump, carburetor and throttle will be the area I wl ask my mechanic to concentrate.

Finally solved the problem,I changed fuel pump,filter, plugs, clean the carburetor and the throttle,check the coil and yet it still persisted and the told me to meet a good electrician.
I know one Yoruba guy who's a wizard in car electrical, he's the person that brought my nightmare to an end. I took the car to him and he test drive it and ask me to come today, he doesn't use scanner bt he went straight to the distributor and do some adjustment,that's all.

I would love meeting this your wizard and lets see the kinda of magic he performs again

Can't he tell/explain to you what exactly he did?
As far as professionalism & competence is concerned, he's adjudged a quack/"Kazeem" until he's able to theorize & explain what went wrong & how he went about solving it !!!!
Pronto!!!

Thank you,

Oga don't waste your resources on futile exercise,it doesn't work that way . Car jerking and stalling are just symptoms of performances issue that can be due to hundred of reason.Other people fix for that similar symptom might not share the same fix with your issues r cos there is underlying root cause this might different .This similar to the same condition of a patience that has headache which can be due to different reason (malaria,typhoid ,cancer etc) What u need to do is to find the root cause of why the car is jerking and stalling and resolve it and that is all .
Simply go for diagnosis .

thanks for your response sir.
they have diagnosed the car twice and the problem persist, thats why am calling out here. i have paid twice for diagnosis and changed some parts but still not solved sir.
