Hey guys, so I’ve been having a big problem with my Ford Escort mk7 1.6 90Ps for two months now! So easy running in empty speed is always going up and down! Then being driving heavy power loss and when driving on the highway the power just goes down to felt 50%! In addition, sometimes the car jerks from 1 to 3 speed extremely doll as if you were constantly giving full throttle and then a full throttle. So far I have used new spark plugs and nd new spark plug cable as well as a new air filter car is running much better but the performance holes are still there as well as that when starting no power is there when the car is started for the first time. Ruckeln did not appear again until now but only tested it for two days. already in advance thanks for the help
