I've got a '78 280Z that starts and runs perfect until the temp come up to normal then it stalls or hesitates when coming off a stop. Once I get it up to speed (2000 RPM or better) it seems to run OK. Any ideas??

This kinda reminds me of Click N Clack with Stump the Chumps. Come on Man! 3 weeks and no replies????

Click N Clack answered you question three weeks ago. Really! test the water temp sensor (they also suggested "burping the coolant").

My 77 has the same condition: runs great cold till I park for a short time, start it up and it hesitates for about a minute of driving then everything is fine. time to look at the coolent I think.
