1975 Ljet 1.8l. The car starts and runs fine in cold weather. When it is warm, the engine cranks and cranks and will not start. Use a little starting fluid, it starts, but unless I keep my foot on the accelerator, it will stall until it warms up. Head temperature sensor???

Have to checked all the hoses that carry the vacuum ? Start with the small hoses, they crack and leakage is barely detectable. If there is a Y connecting hoses, make sure its not cracked. Then move to the AAR to Plenum hose, pull it and put a rubber stopper in the plenum ( Home Depot has these) Then move up to the hoses that go into the boot, they gotta seal real good. Lastl, check the gasket between the throttle body and the plenum. 914 rubber makes replacements now.

I installed a vacuum gauge into one of the lines that connect to the plenum. When everything is right, it reads a steady 18 at idle; when there is a vac leak it occilates.

If. none of these pan out; it could be the T! sensor connection or the sensor itself

Good luck with this... (IMG:style_emoticons/default/smile.gif)
