just been at the garage playing with the Escort and the 1.6 zetec. So I cleaned the Maf that it was originaly fitted to the engine and it came a little bit better, but still it was stopping after leaving it free. I noticed that the revs where a little bit low (600rpm) so from that idle screw I put it up to 1000rpm. Till now seems to be Ok, will find out more when it makes some miles. Thanks for the help.
