Thanks for the ideas so far! I might help if I give you a little more background on the problem. When I first bought the car it was running very, very rich. The CO had already been adjusted (plug was removed) when I drove the car home day one. I have since then replaced the plug with the DMC Houston replacement. After installing most of the parts in the PJ Grady service kit, I adjusted the CO mixture to keep it from smoking. When cranking while not using starter fluid I don't smell unburned fuel and the fumes don't run me away (anymore). Once started the car runs very smooth at idle. If you slowly give it gas the car will rev all the way to redline (well it could if I tried). While the car has about 16 gallons an new gas in the system, I know there is some gas left in from were it was sitting. This old gas might explain why when you really get on the throttle fast the car will spit and sputter a little. For all I know that bit of old gas might be my starting problem. The idle micro switch seems to be adjusted and working properly (click, click, click). As far as the car having lots of power while driving, I really couldn't answer this. My car is an automatic and I have only rode in a few DeLoreans that were running properly (all manual). I have been adding fuel system cleaner as a fuel it up, but I haven't got it out enough to really get the new gas and cleaner worked through the system. I guess I will get it out this weekend and see how it does. Thanks Again!
