hello,
i´m from germany and i ave a problem with my 93 fd.
nobody can help me so i will try my luck here!

when my car is cold and i will start it,it runs very bad,it runs very unround and not on 3000rpm.
but only a short time until it warms up.
but when the car is cold and stands in the sun for some time it runs much better and also up to 3000rpm.the trunk engine is new so i think thats not the problem!
so who can help me?

THANKS NIKLAS

Where in Germany are you? (Sometimes I fly into Munich and to get to Heidenheim-auf-der-Brenz).
