thank you all guys.

8) after months of trying to find out what was wrong with "christine" (my 86300zx) the z specialist has found the problem and fixed it. my ECU was not in good working order and the wires coming from it going to my fuel injectors has a short in them. So needless to say they had to replace them and rewire it. she is running like new and i hope to enjoy her for many more years to come! thanks for all of your suggestions and happy motoring!!
