Hey I'm new here I have a 75 targa that I purchased 8 months ago and have been fighting a cold start problem. It cranks then revs to 2500 or so then dies and repeats this for several cycles then stays running rough for a few mins then all is good. Every start after that is perfect till it cools down again. I hav replaced the cold start valve and fuel filter with no results. Can anyone help? Thanx , David.
