Hi, I am wondering if someone could help me with my problem. Just finished an engine overhaul on my 1.6 blacktop. Done this before on other cars so no I am capable, well, I reassembled the car yesterday and fired her up, she making an awfull noise (sounds like missfire) but after about 10 mins of driving the sounds stop, the shuddering under acceleration on lower revs stop and the car drives perfect (thats why I say temperature related)

Can anyone shed any light on this for me? also, if someone can provide info on the spark before top dead I would be greatfull as I believe it could be pinking more so than missfiring as my spark angle is 12 before tdc.

Cheers.

Dan
