    Service engine now, no power

    I need help all. My 65 plate ST runs perfect round town, but if I'm on the motorway and put it into 6th and accelerate I get a jolt and a message on my dash saying "service engine now" and the car turns off. I have to pull over and start it back up again. Has anyone else had this problem its driving me mad

    I had something similar recently, but not as extreme with the car shutting off. Would run perfectly up to about 13 lbs and then it would shutter and cut power with any more throttle input. Turned out to be cyl. 4 ignition coil. Dealer fixed it under warrantee.

    I suggest never putting it in 6th and giving it gas. I only accelerate in lower gears, even 5th is to high for most driving.

    No codes is odd. Even though there are no codes have you tried to clear codes system wide anyway if your tool allows for it?

    Because you say there's a jolt, does the car have traction control? If so, have you tried different modes to see if that makes any difference? Ford went through some similar odd symptoms when they first integrated AiM's electronic steering in to the PCM. Some unexpected and indirect system communication was going on that had to be figured out. You might want to consider picking up an inexpensive data logger like those on ebay to see if you can catch something the PCM isn't saving or your scanner isn't catching.

    Edit:

    "No mate nothing."

    I'm guessing you're not in the states? Are you by chance located in an area where Ford is still using the Hitachi MAF sensors that also have the analog and frequency sensing capability? If so, unplug it during a cold start and see what happens.
