We recently changed the radiator on a 1988 RX7. Although we put everything in, the car will not idle. It will turn over and and start but immediate turns off. Does anybody know what we can look at or something we may have done wrong?

 

can you keep it running at all? try holding the afm flap open slightly. if it runs while holding the flap open slightly you may have accidentally disconnected a vacuum hose. otherwise I would check that all the coolant temp sensors wre plugged in and that you didn't accidentally unplug a coil.

 

Also, welcome to the forums!
