I found that my car (Seat Leon Cupra 1P) jerk when I letting off the throttle. The car runs quite good under acceleration and there is in my opinion no issue. I tried different MAF sensor and solenoid because I also have a small missifire when car is iddling. Found that my timing chain should be changed because in VCDS is -5KW. There is a little smell from oil cup like gas. Compresion is good. 170/170/180/170. What could be wrong? It happens only when I let off the gas...
