i drove my car around today, new spark plugs, lead, fuel filter n all, oil, coolant and cool.

i slowly reved it up but when it got to 2000rpm it started jerking hard. really hard.

only way i could avoid it, was to full on accelerate up. past 2000rpm then it would rev past 2000rpm normal.

i drove like this for 2mins, then poped bonnet and smoke was coming out, turbo side of engine.

what's causing these problems?

the smoke is coming up from the area circled in red

 

my na did smoke after i changed my oil. did you check your timing? if its off the motor will run eraticly and misfire alot. also you could have disconected somthing cuasing it to hesitate
