2.0 Fiesta.

The problems i am having is when the engine is cold it idles between 500 - 1000 rpm intil it warms up a little which is about 3 mins. I am using 5w 30w as its the S1 Zetec and i have been informed they have sticky vavle issues.

Secound one is in first gear @ about 2000 2500 revs it lags slightly.

and last but not least when i take my car up to about 5000 revs it seems not to have any more power. I have the fiesta si 1.6 gearbox on it.
