Hey everyone,
I own a 63 plate fiesta st2 running mountune mr230 package. I am having a big performance issue, when I am putting my foot down there are times when my car won’t go past 4.5k revs when I’m driving which then stops the car going any faster. I haven’t had an issue with this until I got it back from where I brought it after finding out there was a leak in one of my coolant pipes, they also had the head gasket skimmed to be on the safe side that it hadn’t warped but the car ran fine before they did the work on it. This has turned it to a big let down for me as I enjoyed the car before this started happening and now it has taken all of the fun out of it. I don’t rag my car often but when I do I can’t have as much fun in it anymore any suggestions would be muchly appreciated.
