Hi all
Can you help? I recently had a corrosion hole in the valley cover which I had professionally welded. The following is a list of things I had done whilst the valley cover was off:
1. Had injectors serviced
2. Changed both TPS's and set to .98v
3. Changed both CO2 sensors
4. New plugs and leads
5. Had new fuel filter and had pump pressure checked

Since I have put it back together it idles really rough and cuts out when cold. It seems as soon as the thermostat opens all is good and it runs a dream. I have checked for vacum leaks and there is none. Both Lubemobile and Autbahn have had a crack at solving the issue via diagnostic checks but have failed miserably both times. Has anyone had the same problem as I would really appreciate some suggestions.

checked cap and rotor?
checked timing?
coolant temp sensor?

Timing is good but will look at cap, rotor and coolant sensor. Thanks

If you try ford they will fix it but be prepared to re-morgage

well consider your self lucky it's not ideling poor when cold mine ideled poor though when hot and cold but better cold worked out being a burnt valve in the heads

have you found out the issue?
im having the same problem with my nf 5 ltr
ford couldnt find the cause nor could 2 other mechanics
ford said i have a vaccum leak after they plugged a screw in tooa vaccum line that gose into the firewall next to the brake booster
