Hello, there I am again with a different problem… since I am now tomorrow or today in the workshop for engine bearing change I would like to fix another problem immediately. My Escort (96er/1.8L/85kw) jerks quite easily, but only at constant speed independent of speed and speed. In addition, the fuel consumption (feeling) is a bit high and my vmax is only about 190 km/h In idle and acceleration it runs round. Now I had two suspects in my head (L MM and Lambdas.) So today LMM is jammed (plug) and so driven –>see there, no more jerking. My questions are now: 1.) Is it now with high probability the LMM or can it be that the engine runs anyway “rounder” because the Essi (without LMM) then runs in this emergency program? 2.) Would the symptoms (vmax too low, high fuel consumption and o.g. jerking) fit to the defective or not properly working LMM? 3.) If it is the LMM then I have to take the new one from the 1.8L or can I use the new one from the 1.8L also take one of nem e.g. 1.4 L Escort? Achso recently had this vacuum hose which runs off at the back of the engine at a 90° angle because it was completely torn. Does the SG have to be re-learned now? I hope it’s not bad that I started several threads now, just wanted to keep it clear, since there are various problems or topics. Greetings
