Its been a while since I've even owned a D-jet car. My 911 does the same thing when the mixture or timing is set incorrectly. I'm also not sure what you mean by inlet air temp meter; perhaps Aux. air regulator, or air pressure meter? When you say you disconnected it: do you mean the hose or the electrical plug? A bad aux. air meter can cause such a problem when cold; but if it happens all the time I might suspect a leaking injector, or cold start valve. Please get back to me as I am very interested in this problem. good luck james Wayne at Pelican Parts wrote: > Hi there.
