RMVS Posted August 23, 2022 Share Posted August 23, 2022 Hello, Got an issue with a 2011 Fiesta MK7 1.2 Petrol. It was purchased after being in an accident. Front end has been repaired but engine has misfire. I have renewed: Spark plugs, leads, coil pack and still the misfire exists. I have pressure tested the cylinders Cylinder 1 is 165 Cylinder 2 is 160 Cylinder 3 is 200 Cylinder 4 is 150 The only thing I can think of next is the throttle body. Anyone have any further suggestions on what it could be? Also note the engine light was on when car arrived and it was the MAP Sensor which was replaced. 1 Quote Link to comment Share on other sites More sharing options...
unofix Posted August 23, 2022 Share Posted August 23, 2022 Have you monitored the engine using FORScan ? Do all cylinders misfire or is it only one ? Quote Link to comment Share on other sites More sharing options...
