  1. Mk2 Engine, Exhaust and Induction
    Well for some time now I've been chasing what can only be described as hesitation/lack of then too much power. I've changed Boost solenoid, cleaned sensors, checked hoses etc. I was going to just replace all sensors then remember somebody on here say that they cleaned all earthing points. Today...
  2. Mk2 Engine, Exhaust and Induction
    Hi guys.... I've had this sense of hesitation on my MK2 ST so I decided to take it out on a FORSCAN data log and see what was going on. It was present before my engine rebuild and my group A + cold air feed was fitted, so I do not have any reason to believe it's the Group A filter. I realise...

    Hi all ST owners, I own a stock Focus 2.0 ecoboost ST MK3 and having intermittent performance issues. I have also previously owned the pre-facelift model and have not had any issues like this with it, so know what to expect from the car. It is not always possible to replicate the issue but it...

    Hey all. Searched topics but after a where to go and try next. Code has been coming up on and off for months. I have changed map sensor 3 times in last year. But came up again this morning as a pending code. No cold start idle just the usual running as if it had been running for a while. Cleared...

    So this weekend, I bought some electrical cleaner and a new set of torx bits to clean my maf sensor (error code and hesitant pulling away). I took the sensor out, nice and easy. The sensor housing/ block that you pull out looked brand new or at not very old at all. To my bemusement, there was...

    Guys, Thought I would put up my experience of boost issues and how I resolved them just in case it helps others. Via the search I found lots of topics which stated what the issues are and suggestions on what could be done to solve them, but very few had instances where someone had actually...

    Afternoon Gents, I seem to be having a couple of intermittant faults with my 2010 facelift. 1) When I get on to long roads i.e motorways, dual carriage way I am getting the traction control light coming on with a huge loss of power. After about 5 mins I get back all the power with full boost...

  15. Mk2 Servicing and Maintenance
    Hi all, MAF sensor has kicked the bucket again. DS unit plugged into the ECU suggests both the sensors are outputting the same reading, 0.05 constant. Just replaced the MAP sensor so this is my next step for fixing it. (Map was defo goosed anyway) Question - will the S60 T5 MAF work on an...
