anyone help,

i got my 2.1 zetec running on MS-I , its just a bit rough when first starting up idles rough even if you try reving it allittle, but after about 7-8 seconds if foot is off pedal it idles ok at about 1300 rpm, but i can hear engine missing slighty every now and then, i dont mean missing from exhaust you can hear the engine miss kind of jump every now and then .

im still scared to give the engine a good rev incase it runs lean

can someone please check the dataloque i also had msq if needed.

With no load on the engine you should be safe revving it up a bit, but obviously beware of full throttle out on the road until you are confident.

You may need to adjust the VE table by +/- 20 so try giving changing things a lot. At idle the worst it will usually do is stall.
