Hey folks,

I have been battling with a problem where the car usually starts and runs, then when I drive down the block it dies with no throttle response. The car will idle somewhat, and runs rough up to about 2K revs, but no higher. When you press the gas very little happens, or the car stalls. The tach is stable, and after a minute or two the car runs fine. I have replaced the fuel injector relay and the radio supression relay, the fuel pressure regulator and RPM sensor. Today it would not start until I cranked it for a while. Finally clears out and runs well.

Now I have error code 3-1-2 in the fuel system OBD. Where do I go from here? The FAQ says a wire break between the EZK terminal #$ and FI#28. Would this cause the sympoms I have noted? Where are these two items, and what can I do to fix this thing and make it reliable again. It is very frustrating. Any and all suggestions are welcomed.

Thanks again for any advice.
