99 2.0 Engine Cuts out and Rev drops on idle - findhosting
The car is vw gti 1999, T reg 2.0litre engine size

I put new engine in my car as previous engine had black soot coming.


With this engine I have change throtle body.


Problem with this car is its rev drops between 12 to 20 and goes to zero.

If i start car and give a gas it goes fine till 12. After twelve and before 20 rev always drop to zero and then rise again. But if i give more gas and rev goes fine after 20.


Same if i drive the car and if my gas pedal goes between 12 and 20 then it drops and cuts out like there is no power in it. I have to give more gas to either keep the rev after 20 to make it driveable.

anyone knows what problem is and how can i fix it. thanks
