Was wondering if anybody else has had trouble with there ST170 hesitating at the top end of the rev range, started misfiring between 6000-7000rpm, took it back to fords and they tried to fob me off telling me it was the limiter kicking in, only since then its got worse and can do it as low as 3000rpm now.
Has this happened to any one else?

Fords have got it now but just keep telling me there are no fault codes on it, i actually had to get the mechanic to come out in it with me before they believed me that there was something wrong.

03 Plate, with 16,000 miles

 

tell them to check the inlet manifold runner control its a little piece of pastic which snaps off there is amodifed part for this now!! also check the right plugs r fitted there are 3 different plugs now for the zetec most dealers use std 2.0 plugs not st ones

 

not had any problems with the top end of the revs but have questions about standing starts in first gear. mine seems really slow in comparison with the rest of the gears.
are the st170's all like this? i have found that poorer performing cars beat me at the lights before i catch them up.
can anything be done to improve pick up in first?
